Abstract

An anti-crack concrete is prepared from the following raw materials in parts by weight: 3-6 parts of basalt fibers, 4-9 parts of a light-silicon fiber anti-crack reinforcing agent, 100-120 parts of cement, 1-3 parts of cellulose fibers, 120-190 parts of pebbles, 2-6 parts of calcium carbonate, 3-6 parts of polyurethane particles, 2-4 parts of bauxite clinker, 3-7 parts of water glass, 0.5-2 parts of a naphthalene-based efficient water reducer, 3-6 parts of silicon dioxide, 2-5 parts of zirconia, 0.5-3 parts of Grace fibers and 50-80 parts of coal ash. The anti-crack concrete has the benefits that the anti-crack effect is very good, as the fibers are added, the strength of the concrete is enhanced, and a certain heat preservation effect is achieved.

Description

technical field [0001] The invention relates to a crack-resistant concrete. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the use of cement as the cementitious material and sand and stone as the aggregate. It has been widely used in industrial and civil construction, water conservancy, urban construction, agriculture and forestry, transportation and seaport and other projects. However, the existing concrete is prone to cracking, which affects the use effect of the concrete. At the same time, the strength and impermeability of the concrete are insufficient. People are working hard to develop a high-performance concrete. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an anti-crack concrete, which has a good anti-cr...
