Preparation method of anti-seepage and anti-corrosion concrete

Abstract

The invention provides a preparation method of anti-seepage and anti-corrosion concrete. The anti-seepage and anti-corrosion concrete is prepared from the following components in parts by weight: 60-200 parts of broken stone, 50-150 parts of fine sand, 20-60 parts of calcium chloride, 120-240 parts of Portland cement, 10-20 parts of magnesium silicate, 12-20 parts of active calcium silicate, 4-15parts of aluminum tripolyphosphate, 6-12 parts of strontium oxide, 4-10 parts of white mud powder, 3-5 parts of sodium phosphate, 3-12 parts of polyvinyl alcohol, 4-10 parts of epoxy resin and 2-12 parts of potassium tripolyphosphate. By adding polyvinyl alcohol, epoxy resin, potassium tripolyphosphate and butyl methacrylate, the concrete has strong anti-seepage and anti-corrosion functions, steelbars in the concrete can be effectively prevented from being corroded, the service life of the concrete is prolonged, and by adding lace fibers and carbon fibers, the anti-cracking performance of theconcrete can be improved.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a method for preparing anti-seepage and anti-corrosion concrete. Background technique [0002] Concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. It is a traditional construction project. Materials are widely used in the field of construction. For concrete, corrosion resistance, acid and alkali resistance, compressive strength and splitting tensile strength are an important indicator for judging the quality. In addition, the corrosion resistance, acid and alkali resistance of concrete is also an evaluation An important factor in concrete.

AI Technical Summary

Problems solved by technology

[0003] Concrete drainage pipes laid underground for a long time are generally used well, and the cost of the pipe itself is very low. However, due to the heavy weight of the pipe, it is difficult to transport and install, and the requirements for the foundation are relatively high (concrete foundation is often used), so the overall cost is not high. Low, and when there are corrosive media inside or outside, corrosion damage will occur, resulting in a decrease in structural strength, failing to meet the requirements of the service life, resulting in waste of energy and resources. The ground subsidence accidents caused by affecting the foundation have gradually increased, which has caused huge economic losses. Therefore, the durability, corrosion resistance and anti-seepage performance of concrete have been paid more and more attention by the engineering and scientific circles.
