Definitions
- the present invention relates to a concrete composition compacted rolled fiber reinforced and a method of making continuous pavements and industrial areas without joints, from said composition.
- Rolled compacted concrete compositions differ conventional concrete poured or spoiled by the fact that, for similar mechanical properties, they require a cement dosage reduced as well as reduced water content. This more water content low allows sufficient lift to implement the material with road vehicles in order to compact it using vibrating compactor and tire compactor and then put it back without delay under circulation.
- the consistency of poured concrete requires using traditional formwork machine techniques sliding or vibrating rule and does not allow recirculation only after a sufficient setting time which is generally at least 7 days.
- the metallic fibers used in industrial paving are most often drawn fibers comprising generally wires of 1 mm in diameter.
- the different fibers differ from each other by the type of active anchor in the concrete matrix.
- This company also manufactures a fiber sold under the brand name "Twincone” which has a cone undeformable at each of its ends.
- This type of anchoring is much more rigid than the anchoring obtained by hooks or undulations, hence its name of fibers with so-called total anchoring.
- concrete comprises, on the one hand, 5 to 10% of the weight of cement in ultra-fine fillers such as silica fumes, which makes it possible to fill the interstitial voids of the concrete.
- BAC continuous reinforced concrete process
- Continuous reinforced concrete which is the benchmark for continuous concrete without joints, presents a fine and close cracking.
- the cracks With compacted concrete reinforced with corrugated fibers, the cracks are spaced but wide.
- “Twincone” fibers When “Twincone” fibers are used, the sum of crack openings is 30% less than that observed in the case of wavy fibers.
- the behavior of anchored fiber-reinforced concrete total approximates that of a continuous reinforced concrete, this fiber allowing a more efficient anchoring than that of corrugated fiber.
- the trials were shown that the evolution of cracks in reinforced compacted rolled concrete "Twincone" fiber is equivalent to that of reinforced concrete cracks continued.
- Figure 1 of the accompanying drawings illustrates the results of a comparative pull-out test of a "Twincone" A fiber with total anchoring and a fiber with deformable anchoring B, the two fibers having an identical diameter of 1 mm.
- the use of fully anchored fibers is necessary for the realization of continuous pavements without joints, these allowing to better limit the opening of cracks.
- patent application FR 2 684 397 defines a composition of concrete for the realization of pavements without joints, having a specific composition which includes anchored fibers non-deformable such as those described in patent applications European EP 130 191 and EP 098 825.
- the purpose of the present invention and to provide a composition of rolled compacted concrete reinforced with fibers making it possible to limit the presence of cracks while ensuring control of the opening of the cracks.
- the hydraulic binder consists a combination, in varying proportions, of clinker, slag ground, fly ash, gypsum (phosphogypsum or anhydrite) and ultrafine (silica fumes, pozzolans).
- the fibers that have been selected in the present invention, to be inserted into a concrete composition rolled compacted led to better results in terms of cracking limitation and control.
- the use of fibers such as defined above, having curved end portions, substantially cylindrical over the entire length, in a composition of compacted rolled concrete surprisingly, provides a fair balance between limiting the number of cracks and limiting the opening of the cracks present.
- Fibers with full or very rigid anchoring have strong anchoring resistance up to a crack opening of 1 mm. However, if the crack opens further, there is a rupture of the fibers and a very rapid drop in the sewing effect of the edges of the rift.
- the fiber according to the invention provides a strong anchoring effect, practically equivalent to that fully anchored fiber.
- the performance of the anchor is kept at much larger crack openings ranging up to 3 to 4 millimeters.
- the composition according to the invention has a ductility plate much safer than the breaking effect observed beyond 1 mm with a fully anchored fiber, for example in the case of localized subsidence of the roadway platform and a crack opening which could exceed 2 mm.
- the threads constituting the fibers have a diameter between 0.65 and 0.85 mm and a length ratio total / diameter between 65 and 85.
- the fibers have a total length / diameter ratio of around 80.
- each curved end part is formed of a rectilinear part connected to the central part by said inclined part comprising at least two elbows.
- the fibers used in the present invention are fibers of 0.75 mm in diameter, with a total length of 60 mm and with a tensile strength of at least 1100 N / mm 2 .
- This fiber also has the advantage, with an equal dosage by weight in concrete, of a number of fibers double that of the number of fibers with a diameter of 1 mm traditionally used. Due to a hardening pushed further to the wire drawing, the thinner wire moreover has a higher elastic limit which makes it more efficient than a wire of 1 mm in diameter.
- the cracking observed in concretes obtained from the composition according to the invention remained limited to values between 0.3 and 1 mm.
- the aggregates of concrete forming the irregular surface of the walls of the crack remain embedded between them and held in position, the effect being ensured by the fibers anchored in the matrix of the concrete on either side of the crack.
- This mutual locking of aggregates between them and fibers which ensures a "seam" of the edges of the crack means that the crack thus controlled does not significantly weaken the overall structure of the roadway.
- the crack is not active, in this sense that it does not evolve under the constraints of heavy traffic during the service life of the roadway. By the way, the edges of the crack remaining mechanically embedded by the intergranular contacts between the constituents of concrete, the fibers are consequently less stressed in fatigue, which ensures good durability of the pavement.
- the aggregates used comprise from 70 to 100% of crushed materials, having sharp angles and a shape close to the square, and a particle size between 0 and 14 mm so as to avoid the phenomena of segregation, that is to say of separation of large elements.
- the concrete composition preferably also comprises a plasticizing aid which facilitates compaction by intergranular lubrication and makes it possible to obtain a density close to 2400 kg / m 3 of concrete with favorable consequences, such as higher strength and the possibility of reducing dosing with hydraulic binder
- the optimal water content is determined by the test Modified Proctor and varies between 4 and 6% of the dry constituents of concrete.
- the composition comprises a content of hydraulic binder close to 250 to 300 kg per cubic meter of concrete, one water content of 4 to 6% of the weight of the dry constituents of the concrete, i.e. approximately 100 to 150 liters of water per cubic meter of concrete, a dosage of metal fibers between 25 and 50 kg, preferably between 30 and 40 kg, per cubic meter of concrete.
- the composition includes 280 kg of hydraulic binder and 110 liters of water per meter concrete cube.
- the adjuvant content is at least equal 0.3% of the weight of the hydraulic binder. It is possible to obtain an effect inter-granular lubrication using a low dosage of plasticizer, for example 0.3 to 0.5% of the weight of hydraulic binder. Through against, the setting effect of concrete, insofar as the same product is used for the plasticizing and retarding effect, cannot be obtained with higher dosages by plasticizer, for example minimum 0.7% of the weight of hydraulic binder if you want to keep the workability of fresh concrete for about 20 hours, for example for a recovery the next day on the concrete of the day before.
- the concrete composition according to the invention can be used for the creation or reinforcement of road structures or industrial areas with heavy rolling loads, such as than those produced by frequent passing of trucks, vehicles heavy or large aircraft for example.
- composition according to the invention allows a layer of concrete with continuously variable flexural strength on a wide crack opening range, for example from 0 to 4 mm, and without breaking the fibers. According to a particularity, the variation of resistance over said range is less than 20% lower than its nominal value.
- the material according to the invention is used through a heavy table finisher, which is a material generally used for the implementation of bituminous materials, or through a grader.
- the concrete is then densified by a compactor weighing several tonnes with one or two rollers vibrant. This compaction can then be followed by a kneading effect brought by the action of a tire compactor applying for example a load of 3 to 5 tonnes per wheel.
- the fiber-reinforced compacted concrete can then be directly covered with a bituminous wearing course, the cure for concrete can be made by an emulsion of gravel bitumen.
- a pavement consisting of a concrete base layer according to the invention, then covered with a bituminous wearing course has the advantage a separation of functions, the cement concrete ensuring a long service life of the structure under heavy traffic, and the bituminous mix making it possible to obtain a carpet having high specific qualities, for example a drainage mix which absorbs rainwater and / or a acoustic coating which limits rolling noise.
- the concrete layer can also be covered with a highly proportioned concrete cement, consisting of a mixture of three components, namely cement, fillerized sand (containing a large proportion of elements fine), and a sand containing few fines, the fillerized sand comprising at least minus 10 to 20% of fine elements less than 0.080 mm.
- a highly proportioned concrete cement consisting of a mixture of three components, namely cement, fillerized sand (containing a large proportion of elements fine), and a sand containing few fines, the fillerized sand comprising at least minus 10 to 20% of fine elements less than 0.080 mm.
- compacted rolled concrete reinforced with fibers according to the invention can be used in pavement reinforcement. Simultaneously with a reinforcement, this process can also solve the problem of rutting of bituminous pavements by adding a thin layer of 5 to 18 cm, covered with a thin or very thin bituminous mix.
- the composition according to the invention comprises metallic fibers constituted by wires 10 provided with curved end portions 12.
- the wires are substantially cylindrical over their entire length L and comprise a central portion 11 substantially rectilinear extending from each side by an inclined intermediate portion 13 which is extended by said end portion 12.
- Each portion 12 is formed of a rectilinear portion connected to the central portion 11 by said inclined intermediate portion 13 comprising at least two elbows.
- the wires have a diameter d of between 0.38 and 1.05 mm, a total length L of between 19 and 80 mm, and a minimum tensile strength of 900 N / mm 2 .
- the two end portions 12 of a wire can have a different or similar shape.
- the length l, l ′ of the rectilinear parts of the end parts 12 can be different or similar and is between 1.5 and 4 mm.
- the inclined portion 13 of each end part forms with the rectilinear central part 11 an obtuse angle ⁇ or ⁇ ′ equal to or less than 160 °.
- the two angles ⁇ , ⁇ 'thus defined can be identical or different.
- One of the intermediate portions of an end portion is not necessarily in the plane formed by the other intermediate portion and the central portion 11. Furthermore, each end portion is not necessarily in the plane constituted by its intermediate part and the central part.
- the transverse offsets h, h 'between the central part 11 and each end part can be identical or different and are at least 0.75 mm.
- the composition according to the invention comprises fibers sold under the brand "Dramix 80/60".
- the "Dramix 80/60" fiber is a fiber which is characterized by a total length L of 60 mm for a diameter d of 0.75 mm, ie a ratio ⁇ of 80, and a tensile strength of at least 1100 N / mm 2 .
- the two angles ⁇ ⁇ ' are substantially identical and the intermediate portions, the end portions and the central portion 11 are substantially in the same plane.
- compositions 1, 2 and 4 differ from each other only by the nature of the fibers that they contain.
- Composition 1 comprises “Twincone” fibers of the fully anchored type
- composition 2 comprises “Dramix FL 45/50” fibers of flattened hook ends type
- composition 4 according to the invention comprises “Dramix 80 fibers”. 60 ".
- the fibers are dosed at 30 kg / m 3
- Composition 3 includes "Dramix FL 45/50" fibers like composition 2 but these are dosed at 35 kg / m 3 .
- the formulation of the concrete compositions has been defined so as to meet a criterion of compressive strength of the order of 50 to 60 MPa, while respecting the size range in force for concretes compacted with a roller (NF P 98 -128).
- the compressive strength measured on cylinders of dimension 16x32 cm, in accordance with the standard in force, is given in table III. The tests were carried out on three concrete cylinders for each composition 1 to 4.
- Curves 1 to 4 correspond respectively to compositions 1 to 4 defined above. The appearance of the crack takes place under a load level of around 25 kN for different compositions.
- composition 1 comprising Twincone fibers show a pressure drop after the onset of crack up to about 0.2 mm opening, then the fibers allow a resumption of effort. From a millimeter of flexural crack, corresponding to the maximum load-bearing capacity, the fibers begin to break, which results in successive charge jumps and a very rapid decrease in the bearing capacity of the prism.
- the prism of composition 4 according to the invention has a slight pressure drop at the appearance of the crack and then a recovery effort.
- the maximum bearing capacity is obtained for an opening crack between 1 and 1.5 mm. Bearing capacity decreases then very gradually.
- composition 2 comprising "Dramix FL fibers 45/50 "dosed at 30 kg, the prism displays a very low pressure drop significant (of the order of 50%) after the appearance of the crack. Beyond a certain crack opening of the order of 1.8 mm, jumps of loads are visible on the curve. These jumps reflect breaks in fibers as in the case of composition 1.
- composition 3 comprising "Dramix FL fibers 45/50 "dosed at 35 kg, the results are similar to those obtained with composition 2, only the increase in the dosage of fibers allows a higher load capacity.
- the capacity to recover from stress after cracking is substantially the same order of magnitude for compositions 1, 3 and 4.
- the fibers have substantially the same potential for cracking for openings restricted to 1 mm. Beyond that, the intrinsic behavior of the fibers, leading to rupture or tearing, modifies the behavior of a cracked section.
- the fiber at total anchorage shows the strongest resistance of the anchorage up to a crack opening of 1 mm. However, if the crack opens more, we are witnessing a break in the fibers and a very rapid decline the sewing effect of the edges of the crack. Up to an opening of 1 mm crack, the fiber according to the invention shows resistance slightly weaker anchoring, of the order of 7%, than that obtained with a fully anchored fiber. However, the performance of the anchor is kept at much larger crack openings ranging from 3 to 4 mm, which is not the case when using fibers fully anchored or other fibers.
