Problems solved by technology

[0003] However, on the one hand, the existing impermeable concrete requires high production technology, on the other hand, its waterproof and impermeable ability is limited, it cannot last long, and it will cause corrosion to the steel bars inside the concrete structure. Therefore, it is necessary to develop new and efficient impermeable concrete.

Abstract

The invention discloses high-anti-permeability concrete. The high-anti-permeability concrete mainly comprises the following components in parts by weight: 100 parts of cement, 50-100 parts of water, 85-115 parts of sand, 200-280 parts of broken stones, 0.5-0.8 part of silicon dioxide particle, 0.5-1.5 parts of ultrafine mineral slags, 2-5 parts of ultrafine quartz sand, 2-6 parts of high-property water reducing agents, 2-5 parts of Sodium dodecylbenzenesulphonate, and 0.5-1.5 parts of hydrophilic colloids. According to the way, the high-anti-permeability concrete is efficient and lasting in anti-permeability and waterproofness, the corrosion of reinforcing steel bars inside a concrete structure is avoided, and the anti-aging performance is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high impermeability concrete. Background technique [0002] Concrete is the most widely used and used building material in civil engineering. Ordinary concrete refers to cement as cementitious material, sand and stone as aggregate, which is mixed with water, poured, formed, coagulated and solidified into "artificial stone" with certain strength, namely cement concrete, which is currently the most widely used concrete in engineering. Variety. However, due to the characteristics of its own structure, ordinary concrete materials often leak during use, especially for those underground and edema structural projects, which seriously restricts the application of concrete materials. Therefore, impermeable concrete was developed. Impermeable concrete improves the pore structure by increasing the density of concrete, thereby reducing the penetration channel and improving th...
