- the ratio of water to Portland cement is from 0.35 to 0.5.
- the aggregate components have the following particle size distribution: up to 0.16 cm - up to 5%,
- a method of manufacturing a ballast coating on a pipeline comprising mixing the starting components, namely, sulfate-resistant Portland cement, barite ore, plasticizing additives based on polycarboxylate ether and water.
- the starting components namely, sulfate-resistant Portland cement, barite ore, plasticizing additives based on polycarboxylate ether and water.
- plasticizing additives based on polycarboxylate ether and water For mixing, take the components in the following amount (wt.%):
- a polycarboxylate ether plasticizing agent from 0.1 wt.% to 0.25 wt.%
- the water for the concrete mixture is pretreated by passing it through a magnetic field in which a voltage of between 120,000 A / m and 140,000 A / m is maintained at a speed of
- the technical problem solved by the proposed invention is the creation of a method of manufacturing a protective weighting concrete coating of a pipeline with a high predetermined density, having after hardening and aging a high strength compression, which in turn allows to obtain a technical result, namely to reduce the outer diameter of the pipes with a protective ballast coating for underwater, underground and surface laying.
- the claimed technical result is achieved by the claimed method of manufacturing a protective weighting concrete coating of the pipeline, which includes mixing cement, aggregate, plasticizing additives and water.
- the resulting mixture is pumped into the annular space formed by the outer surface of the pipeline and fixed formwork installed on it with a gap.
- the resulting coating is left to harden.
- Portland cement is fed for mixing based on its content in the mixture from 8.8 mass% to 20.0 mass%
- water is introduced based on the ratio of water to cement equal to 0.31 to 0.63.
- a plasticizing additive for mixing serves plasticizer with antifoam.
- the amount of plasticizing additive used in the mixture is from 1 kg / m to 3 kg / m.
- the aggregate to be mixed must contain a grain size not exceeding 10 mm.
- the aggregate is selected from barite or iron ore, or gabrodiabase, or granite.
- the mixing of the components together or separately is carried out based on the calculation of a mixture having a yield index, measured by the cone blur of 55 cm to 75 cm, and an air content of 1% to 4% of the volume of the mixture.
- the best indicator of the density of the protective weighting concrete coating supplied to the mixing aggregate has the following particle size distribution: up to 0.16 mm - up to 8%, from 0.16 mm to 1.25 mm - up to 35%, from 1.25 mm to 2.5 mm - up to 37%, from 2.5 mm to 10.0 mm - the rest.
- plasticizer of the mixture to use lignosulfonates, melaminesulfonates and naphthalenesulfonates individually or their mixture in any combination should be up to 1% by dry matter of the mass of cement.
- the plasticizing additive of the antifoam was not more than 50% of the applied plasticizer.
- the amount of plasticizer is selected so that the material obtained is flowable on the one hand, namely, the cone spread should be from 55 cm to 75 cm, and on the other hand, the content air should be in the range from 1% to 4% of the volume.
- the plasticizing additive supplied to the mixing consisting of a plasticizer and antifoam in an amount of from 1.0 kg / m to 3.0 kg / m of the mixture, at the same time allows to obtain a plastic concrete mass that will fill the entire space between the pipes and the same time after hardening, the concrete coating will have a high density.
- the content of antifoam should not exceed 50%.
- An increase in the content of antifoam leads to a sharp decrease in the fluidity of the concrete mixture and the appearance of voids in the concrete coating, which reduces the compressive strength of the concrete coating.
- Low antifoam content of less than 1% leads to an increase in air content in concrete mixture and as a result, the density of the concrete coating decreases.
- the ratio of water to cement selected in the range from 0.31 to 0.63, is necessary to achieve the required mobility and strength of the concrete material.
- the use of water in a smaller amount leads to a decrease in the mobility of concrete and the appearance of air voids after solidification, and an increase in water leads to delamination and loss of compressive strength of the concrete coating.
- the initial components of the mixture are prepared.
- the process of preparing the components of the concrete mixture includes grinding an inert aggregate, such as barite ore, to a size not exceeding 10 mm.
- the use of larger fractions of aggregate leads to a decrease in the density of the resulting coating.
- barite ore is heated to 5 ° C (maximum), especially watching the melting of sticky (frozen) pieces of rock to prevent separation of the ballast mixture during transportation. Then measure the moisture content of barite ore.
- Barite ore is sieved through a borate to isolate coarse impurities. Then, barite ore and Portland cement in the amount of its content in the mixture from 8.8% to 20.0% are fed through a conveyor system to the scales, where the components are weighed according to the specified composition.
- the particle size distribution of the aggregate is shown in Table 1, the choice of ratios is due to the ballast coating with a given density.
- the plasticizing additive is a mixture of plasticizer and antifoam. Moreover, the amount of antifoam in the plasticizing additive should be no more than 50%. As antifoam, you can use tributyl phosphate or silicone anhydrous self-dispersing antifoam brand Penta-4604. As a plasticizer can be any known plasticizers, for example lignosulfonates, melaminesulfonates and naphthalenesulfonates. These plasticizers can be used individually or in any combination, which does not affect the receipt of the claimed technical result. The amount of plasticizer should be no more than 1% by dry matter of the mass of cement.
- the resulting concrete mixture is pumped by the concrete pump into the space between the conductive pipe and the fixed formwork installed on it.
- the assembled pipe structure is located on a stand installed at a certain angle.
- the solution is injected through special removable plugs at the end of the pipe.
- the poured structure is located obliquely (one end is lower than the other) and the fill is made from the end located below.
- Concrete mixture is pumped by a concrete pump until the structure is completely filled - until the mixture exits the nozzle of the structure cover located above. After completion of the procedure for filling the structure, it is on the stand for a soaking time of at least 5 MPa, and then it is stored until the transport strength is at least 22 MPa.
- steel spiral formwork can be made with locks outside and inside the structure and can be painted or coated with various polymeric materials, which allows to obtain various product characteristics.
- reinforcement (steel or polymer) in the form of rods or mesh connected by welding or connected, and also to strengthen the strength of concrete, it is possible to use fiber (steel or polymer).
- the claimed method allows with high accuracy to provide the specified density of the protective concrete weighting coating of the pipeline in the range from 2600 to 3400 kg / m 3 .
- the determination of the average density of the mixtures was carried out in accordance with GOST 12730.1-78.
- the compressive strength of concrete was determined in accordance with GOST 10180-90.
- the fractional row is crushed (prepared) for each component separately.
- the small and large fractions of the aggregate consist of the same component and in the ratios shown in Table 1.
- Table 1 shows the particle size distribution of the aggregates. The presence of a fine fraction of aggregate allows you to create conditions that reduce the delamination of the protective weighting concrete material during the pouring process.
- Table 2 shows examples of different compositions of the protective weighting coating of the pipeline using components of different densities and gives the compressive strength of the obtained ballast material for each composition, as well as data on the coating obtained in accordance with the prototype.
