Abstract

The invention discloses efficient anti-cracking concrete. The efficient anti-cracking concrete is prepared from the following raw materials in parts by weight: 6-13 parts of manganese ore slag, 60-80 parts of cements, 3-8 parts of oxidized paraffin soap, 4-7 parts of bentonite, 2-6 parts of zinc sulfate, 3-5 parts of zirconium oxide, 7-9 parts of sodium fluosilicate, 30-60 parts of sand, 1-3 parts of Grace fibers, 7-9 parts of anhydrite, 4-10 parts of active excitants, 3-6 parts of curing agents, and 5-11 parts of tetra calcium aluminoferrite. The efficient anti-cracking concrete has the beneficial effects that the concrete has a good anti-cracking effect, and is high in caking property, high in durability and anti-permeability.

Description

A kind of efficient anti-crack concrete

Technical field

The present invention relates to a kind of efficient anti-crack concrete.

Background technology

Concrete is requisite important materials in building operation, but because of concrete be kind of a hard brittle material, be easy to produce crack, especially when building tunnel, bridge harm larger.Therefore requirements at the higher level are proposed to concrete anti-permeability performance, resistance to cleavage and long term life, develop that a kind of working strength is high, the concrete of water-proofing anticracking becomes people's urgent problem.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provide a kind of efficient anti-crack concrete, have the effect of good freedom from cracking, cohesiveness is good, has good weather resistance, impermeability simultaneously.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of efficient anti-crack concrete, is made up of the raw material of following parts by weight:

Manganese mud 6-13 part, cement 60-80 part, oxidized paraffin wax soap 3-8 part, wilkinite 4-7 part, zinc sulfate 2-6 part, zirconium white 3-5 part, Sodium Silicofluoride 7-9 part, sand 30-60 part, Grace fiber 1-3 part, anhydrite 7-9 part, activity excitant 4-10 part, curing agent 3-6 part, tetracalcium aluminoferrite 5-11 part.

The invention has the beneficial effects as follows, efficient anti-crack concrete of the present invention, has the effect of good freedom from cracking, and cohesiveness is good, has good weather resistance, impermeability simultaneously.
