A kind of anti-seepage concrete and preparation method thereof

Abstract

The invention relates to impermeable concrete and a preparation method thereof. The impermeable concrete comprises a cement mortar layer at a bottom layer and a waterproof layer at an upper layer, wherein a waterproof base layer is firstly paved and then the waterproof layer is paved within 1-2h after the cement mortar layer is poured. The impermeable concrete has the beneficial effects that (1) the impermeable concrete comprises the cement mortar layer and the waterproof layer, so that the concrete has good waterproof effect, cohesiveness and miscibility and high strength and is suitable for use in a low-temperature environment through controlling a water cement ratio, controlling the stirring temperature and adding an assistant and other conditions; (2) a waterproof reinforcing layer is further crack-resistant and impermeable, so that the anti-permeability effect is better and the service life is prolonged; and (3) the preparation material of concrete is easily available and low in cost.

Description

technical field [0001] The invention relates to an anti-seepage concrete and a preparation method thereof, belonging to the technical field of building material preparation. Background technique [0002] With the rapid development of cities, construction projects, bridge projects, water conservancy projects, etc. have increased. Most of the construction projects include concrete projects with anti-seepage requirements, and there are certain requirements for anti-seepage effects. However, there is a lot of water and humidity in the ground or water bodies, so waterproofing is very important. And once a leak occurs, it will cost a lot of money to repair it, and it will not achieve a good effect. Therefore, when choosing concrete at the beginning, you should choose concrete with good anti-seepage effect. The impermeability of concrete directly affects the resistance of concrete. Freeze and corrosion resistance. Building impervious concrete is developed on the basis of ordinary...

AI Technical Summary

Problems solved by technology

Therefore, the impermeability of concrete is affected by many factors, and each factor needs to be within a reasonable range to obtain concrete with good impermeability. Too much or too little may have adverse effects. For example, although pozzolan cement is resistant It has good permeability, but its frost resistance and heat resistance are poor, and its shrinkage size changes greatly, so it is not suitable for rigid waterproofing of roofs.
