Abstract

The invention discloses an anti-cracking concrete. The anti-cracking concrete comprises the following raw materials in parts by weight: 55-68 parts of cement, 70-100 parts of quartz sand, 20-40 partsof pottery sand, 0.5-1.1 parts of composite fibers, 3-8 parts of cordierite, 0.9-2.7 parts of light calcined magnesia, 7-15 parts of silica fume, 1.8-2.8 parts of zeolite, 4-8 parts of agstone, 1-3 parts of lead-zinc tailings composite powder, 0.2-1.3 parts of steel slag powder, 1.2-3.5 parts of rice husks, 0.5-2 parts of alumina hollow balls, 0.5-2 parts of calcite in powder, 0.1-0.28 part of epoxy resin latex, 1-1.8 parts of a waterproofing agent, 20-28 parts of water, 0.6-2.6 parts of a water-reducing agent and 0.1-0.32 part of sludge. The anti-cracking concrete is high in strength, good intoughness, anti-cracking and long in service life.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a crack-resistant concrete. Background technique [0002] Concrete is the largest construction material today, and high-performance concrete represents the development direction of concrete technology. In recent years, with the vigorous development of the domestic construction industry, the requirements for the strength and crack resistance of the concrete consumed in the construction process have been continuously improved. Cracks, the appearance and expansion of cracks will reduce the performance, shorten the life, and limit its application. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an anti-cracking concrete, which has high strength, good toughness, anti-cracking and long service life. [0004] A kind of anti-cracking concrete proposed by the present invention, its raw material c...
