Concrete product and production process thereof

Abstract

The invention discloses a concrete product and a production process thereof, and relates to the technical field of concrete product production. The concrete product is composed of the following raw materials by weight: 100-200 parts of cement, 30-80 parts of fly ash, 50-150 parts of straw particles, 20-50 parts of regenerated gravel, 10-20 parts of a tackifier, 5-10 parts of a foaming agent, and 1-5 parts of silicone amide, wherein the foaming agent is hydrogen peroxide, and the average particle size of the straw particles is 1-5 mm. The production process comprises the steps of mold release agent smearing, concrete pouring, surface treatment, steam curing and the like. A certain amount of the straw particles and regenerated gravel are added into traditional concrete materials so that the effect of waste utilization can be achieved, the environmental protection property of the product is improved, and environment pollution is reduced. The added foaming agent can enable a large number of bubbles to be formed in the product, and the product has the characteristics of high strength, light weight, heat insulation, heat preservation and the like.

Description

technical field [0001] The invention belongs to the technical field of concrete production, and in particular relates to a concrete product and a production process thereof. Background technique [0002] Concrete products are increasingly widely used in engineering structures due to their good quality controllability and rapid preparation in large quantities. Existing concrete slabs have also developed various types according to market demand, such as concrete slabs with patterns on the surface. [0003] At present, in the production process of a concrete slab with a pattern on one side, after pouring the concrete slurry, it is necessary to use a vibrator to vibrate it, and then use a smoothing mechanism to smooth it. The knurled roller forms concrete products with patterns on the upper surface of the concrete, but because the concrete itself has a certain viscosity, especially in the cold northern regions, the temperature of the concrete slurry is low, and the surface of t...

Problems solved by technology

[0003] At present, in the production process of a concrete slab with a pattern on one side, after pouring the concrete slurry, it is necessary to use a vibrator to vibrate it, and then use it The troweling mechanism performs smoothing. After smoothing, a roller with knurls printed on the surface is used to form a concrete product with a pattern on the upper surface of the concrete. However, because the concrete itself has a certain viscosity, especially in the cold north In areas where the temperature of the concrete slurry is low, the surface of the roller is more likely to adhere to the concrete slurry, resulting in a significant decline in the quality of the rolled pattern. The usual practice is to set a scraper on one side of the roller, but the effect is limited. For high-precision It is not applicable for pattern printing
