Problems solved by technology

[0003] Concrete is widely used in the field of construction, so people tend to pay more attention to the strength of concrete. However, traditional concrete can meet the requirements in hardness, but it is not satisfactory in hardness. A certain amount of damage occurs, and after long-term use of traditional concrete, due to temperature changes and vibrations, tiny cracks are prone to appear inside it, which will have a certain impact on the strength of the building over time, increasing the risk factor

Abstract

The invention relates to the technical field of concrete manufacturing, and discloses anti-cracking concrete with high toughness. The anti-cracking concrete is prepared from : 10 to 20 parts by weight of methyl allyl polyoxyethylene ether, polypropylene fibers and basalt fibers. The weight of the concrete is effectively reduced, the loss of water is effectively prevented, and the cracking resistance of the concrete is improved. Meanwhile, carbon fibers are added into the concrete, so that a good connecting effect is achieved, the porosity of the concrete can be effectively reduced; fine stones, zeolite and barite are added, so that a good filling effect can be achieved, harmful holes in the concrete can be reduced, the compactness of the concrete is improved, and the concrete has certain toughness; with the addition of the rubber liquid, the viscosity among the material particles in the concrete is increased so as to effectively enhance the integrity of the concrete, effectively enhance the strength of the concrete, reduce the occurrence of the concrete cracking condition, and further achieve the effects of good toughness and cracking resistance of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a crack-resistant concrete with good toughness and a production method. Background technique [0002] Concrete refers to the collective name of engineering composite materials that combine aggregates into a whole by cementitious materials. It is widely used in civil engineering. However, there are certain problems in today's concrete. The main problems are as follows: [0003] Concrete is widely used in the field of construction, so people tend to pay more attention to the strength of concrete. However, traditional concrete can meet the requirements in hardness, but it is not satisfactory in hardness. A certain amount of damage occurs, and after long-term use of traditional concrete, due to temperature changes and vibrations, tiny cracks are prone to appear inside it, which will have a certain impact on the strength of the building over time, increasing the risk fact...
