A high-strength anti-seepage concrete

Abstract

A composition used for high-strength impermeable concrete. The composition contains sand, stone, cement, water reducer, water and reinforced impermeable sand. The reinforced impermeable sand includes aeolian sand and binder covering the surface of the aeolian sand. The reinforced impermeable sand can fill the gap between the sand and the stone, and well combine various components in the composition, and suppress the seepage phenomenon of the molded concrete, thereby greatly improving the strength and impermeability of the concrete.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength anti-seepage concrete. Background technique [0002] Concrete is one of the most important civil engineering materials in the contemporary era. It has the characteristics of abundant raw materials, low price and simple production process; it also has the characteristics of high compressive strength, good durability and wide range of strength grades, so it is widely used in various civil Engineering. [0003] Ordinary concrete is a kind of artificial stone made by mixing cement, sand, stone, admixture and water and hardening. Sand and stone play a skeleton role in concrete and inhibit the shrinkage of cement. Cement and water form cement slurry, which wraps on the surface of sand and stone and fills the gap between sand and stone. The cement slurry acts as a lubricant before hardening, so that the concrete mixture has good working performance. After hardening, t...

Problems solved by technology

[0004] However, in recent years, with the development of the construction industry, the requirements for building materials are also constantly increasing, especially the requirements for concrete, which is the most widely used building material, are becoming more and more stringent. Ordinary concrete can no longer meet the requirements of modern Building strength and anti-seepage requirements

Although there are many new concretes appearing continuously, their concrete strength and anti-seepage effect are still relatively low, and the concrete strength and anti-seepage effect need to be further improved and enhanced.
