Crack-resistant anti-seepage concrete and preparation method thereof

Abstract

The invention relates to crack-resistant anti-seepage concrete and a preparation method thereof, and mainly solves the problem that the concrete is easy to crack and leak. The crack-resistant anti-seepage concrete comprises 280 to 290 parts of cement, 105 to 115 parts of fly ash, 790 to 800 parts of sand, 1050 to 1060 parts of crushed stone, 1 to 10 parts of a water reducing agent, 2 to 7 parts ofwhite sugar, 20 to 30 parts of a fiber expansion agent, 20 to 30 parts of a crack-resistant anti-seepage agent, 3 to 10 parts of a water repellent, 95 to 105 parts of coal gangue, 73 to 83 parts of metal silicon powder, 40 to 50 parts of iron powder, 65 to 75 parts of copper ore tailings, 10-20 parts of a reactant and 148 to 158 parts of water. The fly ash, the sand, the crushed stone and the copper mine tailings are selected as main raw materials, the production cost of the raw materials is reduced, the anti-wear and anti-erosion ability of the concrete is reduced, the durability of the concrete is improved, and the compactness of the concrete is improved. The crack-resistant anti-seepage concrete has better frost resistance and seepage resistance, and the unique crack-resistant anti-seepage agent is added to the concrete to greatly improve the crack resistance and seepage resistance of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a crack-resistant and anti-seepage concrete and a preparation method thereof. Background technique [0002] As one of the most important building materials at present, concrete is used in almost all modern buildings. However, due to the widespread shrinkage of concrete (especially large-volume concrete and high-strength concrete, etc.), the performance of concrete cracking, strength, anti-seepage, and corrosion resistance is reduced. , The heat of hydration of concrete is high, the shrinkage and deformation of concrete are large, and phenomena such as concrete cracking and leakage are common, and at the same time, the strength of concrete is greatly reduced. [0003] With the continuous development of concrete composition materials, people's performance requirements for concrete are not limited to compressive strength, but on the basis of strength, more attention is paid to the...

Problems solved by technology

[0004] In order to overcome the deficiencies of the background technology, the present invention provides a kind of anti-crack and anti-seepage concrete and its preparation method, which mainly solves the problems of easy cracking and leakage of concrete. The present invention selects fly ash, sand, crushed stone and copper mine tailings As the main raw material, the production cost of raw materials is reduced. By adding metal silicon powder, the anti-wear and anti-erosion ability of concrete is improved. By adding coal gangue, the durability of concrete is improved, and the compactness of concrete is also improved. Good frost resistance and impermeability, and the addition of a unique anti-crack and anti-seepage agent in the concrete greatly improves the anti-crack and anti-seepage ability of the concrete
