Abstract
The invention relates to high-temperature resistant anti-permeability concrete. The high-temperature resistant anti-permeability concrete comprises following raw materials by weight: 400-450 parts of Portland cement, 700-800 parts of basalt broken stone, 350-400 parts of medium sand, 120-180 parts of water, 90-120 parts of expanded glass microbeads, 60-80 parts of alkali-resistant glass fibre, 40-60 parts of redispersible latex powder, 5-15 parts of cellulose ether and 10-15 parts of a polycarboxylic acid efficient water reducer. The high-temperature resistant anti-permeability concrete adopting the formula has advantages of high-temperature resistance, high anti-permeability performance, high compressive strength, high rupture strength, good anti-cracking performance, excellent thermal insulation performance, and the like.
Description
Technical field
