- the lightweight dry concrete premix is packed in unit portions.
- the invention further relates to a process for preparing doped concrete by embedding glass fiber reinforced ground thermoset plastic waste in hydraulic concrete mortar prepared with cement, where in the process said lightweight dry concrete premix is mixed with graded gravel, sand, water and optionally other dry additives commonly used in the preparation of concrete mortar, then the final consistency of the concrete mortar is adjusted with continuous agitating and the resultant concrete mortar is poured and allowed to set.
- the concrete mortar prepared by any of the above processes is placed with pouring, self-spreading technology or with framework technology, in step-by-step or continuous process or by preparing discrete elements.
- the invention further relates to a concrete product prepared by any of the above processes, containing the following components expressed in % by volume of the concrete:
- the average particle size of the glass fiber reinforced ground thermoset plastic waste is 300 ⁇ or more.
- the , average particle size of the glass fiber reinforced ground thermoset plastic waste is between 500 ⁇ and 3 mm.
- glass fiber reinforced thermoset waste glass fiber reinforced thermoset SMC and/or BMC and/or FRP waste comprising more than 10 % by volume glass fiber is used.
- the other additives are materials advantageously influencing the preparation process or the features of the end product.
- they are colorants, materials influencing the setting rate, antimolding agents, freezing point lowering agents and the like.
- the concrete product is a concrete building element or a discrete element, which is preferably a pre-product, a cover element or a mobil element.
- the cement is preferably Portland cement.
- Building elements prepared from this high-strength concrete can advantageously be used in building construction and civil engineering and also for preparing discrete elements, for example structures. Moreover large amounts of high-strength concrete products are consumed by road and railway construction. Concrete can be prepared in small amounts or in large scale, further it can be job-mixed or machine-made and produced by an automated process. Concrete transporting is technically solved, concrete placing technologies are available.
- the present invention relates to the preparation of concrete doped with glass fiber reinforced thermoset waste which is prepared by combining hydraulic concrete with glass fiber reinforced ground thermoset plastic waste.
- the process according to the invention is disclosed below in detail.
- glass fiber reinforced thermoset plastic is prepared for grinding, foreign materials, such as metals are separated, then it is ground expediently in multiple steps, that is, coarse grinding and fine grinding is carried out.
- the average particle size of the ground material is adjusted to one order of magnitude larger than the average particle size of the cement to be incorporated. In view of the fact that the average particle size of the Portland cement is about 30 ⁇ , grinding of the plastic waste is continued until its particles reach a size equal to or larger than 300 ⁇ .
- the concrete mortar taking up the ground plastic is prepared and homogenized, where the components of the concrete mortar are: Portland cement, filtered purified water, river gravel and sand.
- the ground component prepared in the first step is added to the concrete mortar obtained above. Finally, the other additives are added, then a final homogenization is carried out and the required consistence is adjusted, then the concrete is poured and allowed to set.
- composition of the concrete prepared according to the foregoing is preferably as follows: 1 1 to 16 % by volume cement, 1 to 16 % by volume ground thermoset plastic, 0 to 2 % by volume other additives, 3 to 10 % by volume purified filtered water and the rest are gravel and sand in ratio 1 :1.
- a premix is prepared from all of the dry components, i.e. from cement powder, dry gravel, dry sand, ground thermoset plastic, expediently by machinery, in an automatic mixing plant with proportionate dosing control, and the wet components are added with continuous agitating, during or after transporting to the place of concreting.
- the invention can be implemented by dry premixing the ground thermoset, the cement powder and optionally the other additives in suitable ratio to obtain lightweight dry concrete premix, which is then portioned out and packed in the form of unit portions, i.e. pre-packed.
- the concrete mortar can be placed by pouring, self- spreading or cradling technology, in step-by-step or continuous process or by preparing discrete elements, for example pre-products, cover elements or mobil elements.
- thermoset plastics otherwise harmful to the environment. Having embedded into concrete commonly used in building industry they do not exert harmful effect on the environment. On the effect of pressure and heat used in the preparation of thermoset the structure of the glass fiber surface decomposes. Activation of the surface is also promoted by the chemical milieu inside the resin. During grinding this surface considerably increases. Glass fibers take part in the hydraulic bonding with relative large activated surface. This explains the outstanding mechanical properties of the doped concrete prepared by the process according to the present invention.
- Reinforced concrete basement subbase is prepared via large scale continuous concrete production.
- the concrete is transported to the place of use in transit mixer with pear-shaped drum, incorporated using mechanical pump on 25°C, then compacted with vibrator rod and the surface is spaded using a finishing disc.
- concrete subbase having structural thickness 55 cm (without blanket insulation) is formed.
- composition of concrete is as follows:
- thermoset glass fiber content : at least 17%) 7 % by volume
- the above composition is cast in place. According to our experience the glass fiber reinforced ground thermoset used is fully covered by the spaded finish of concrete. The embedded glass fibers take a substantial part in the hydraulic bond. The hardened surface is event, crack-free and can be coated without a leveling course. Hygroscopicity of the final concrete subbase was not experienced. Mechanical properties of standard cast-in-place cubes were examined in mechanical test laboratory, where all the received data surpassed the data measured for the references (see Table after the Examples).
- Public road bed is prepared by continuous spreading in standard breadth and average depth of 50 cm. The conditions of preparation and pouring were identical with those described in Example 1.
- composition of concrete is as follows:
- thermoset containing mixed glass fiber
- one half is from 24 to 30 mm and the other half is kule gravel with sizes up to 63 mm 50 % by volume of the rest and
- the concrete bed prepared this way takes up the glass fiber reinforced plastic waste otherwise qualified as harmful to the environment. After hardening the concrete has a closed surface, the embedded ground plastic is not released. Owing to its physical properties, i.e. good waterproofhess, no dissolution was experienced.
- the glass fiber takes an active part in hydraulic bond and shows characteristics of pure silicate.
- the mechanical strength of the concrete prepared according to this process is better than those of the concrete bed materials of control compositions (see in the Table).
- Fencepost elements are prepared from pre-packed dry lightweight concrete premix.
- the size of the post at base is 20 x 20 cm and at cap is 10 x 10 cm, its length is 3 m.
- the fence element is equipped with four reinforcing iron accessories of 10 cm having extending galvanized lugs for fixing wire mesh.
- the concrete is mixed in place and a gauge is used for pouring.
- the concrete may be agitated manually or mobil concrete mixer can be used.
- the proposed composition is as follows:
- thermoset thermoset
- Colored outdoor going elements, flags are prepared in size 40 x 40 x 8 cm using gauges, by the home-made process outlined above.
- the proposed composition is as follows: ⁇ pre-packed lightweight dry concrete premix containing
- thermoset thermoset, and sand 45 % by volume
- the table below shows the characteristic data of the samples prepared from the concrete products of the present invention, which were determined by the standard methods described above, as compared to data determined under similar conditions, of concrete products comprising glass fiber reinforced plastic waste representing the closest prior art.
- a great advantage of the present invention is that it contributes to the removal of plastic waste by using it in concrete prepared for the building industry, thereby decreasing harmful effect of said waste on the environment.
- a further unexpected effect of the present invention is that the characteristics of the concrete products, such as tensile strength, bending strength, impact strength, abrasive hardness, compressive strength and resistance to shear and extreme conditions, like fire- resistance and frost-resistance, and crack resistance are highly improved.
