Abstract

The invention provides an anti-cracking concrete. The anti-cracking concrete is prepared from the following raw materials in parts by weight: 7-12 parts of industrial aluminum sulfate, 5-9 parts of high-strength steel-wire-like fibers, 60-80 parts of dinas, 3-8 parts of siderite, 90-150 parts of cement, 5-9 parts of diatom ooze, 7-10 parts of calcium carbonate, 8-15 parts of blast furnace slag, 3-6 parts of sodium carbonate, 0.5-2 parts of sodium hexametaphosphate, 2-4 parts of aluminum hydroxide, 2-6 parts of coal ash, 6-10 parts of dicalcium silicate and 9-14 parts of lithium slag. The anti-cracking concrete has the beneficial effects of excellent anti-cracking capability, and meanwhile, low water consumption and reduction of resource waste; and besides, the anti-cracking concrete is good in fluidity and low in deformation.

Description

technical field [0001] The invention relates to an anti-crack concrete. Background technique [0002] Concrete is an essential and important material in building construction, but because concrete is a brittle material, it is easy to produce cracks, especially in the construction of tunnels and bridges. Therefore, higher requirements are put forward for the impermeability, crack resistance and long-term life of concrete, and the development of a concrete with high working strength, waterproof and crack resistance has become an urgent problem to be solved. 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 good anti-crack ability, and at the same time uses less water to reduce waste of resources; and has good fluidity and small deformation. [0004] In order to solve the deficiencies of the prior art, the technical solution adopted by the...
