Abstract
The present invention relates to a kind of enhancement mode anti-crack concrete, including corundum, sodium bentonite, coarse aggregate, fine aggregate, rubber grain, polystyrene foam particles, breeze and Talcum, its feed components by weight, 80 100 parts of described corundum, sodium bentonite 30 35 parts, coarse aggregate 45 51 parts, fine aggregate 37 47 parts, rubber grain 10 20 parts, polystyrene foam particles 10 15 parts, breeze 30 40 parts and 20 25 parts of Talcum.The corundum used in concrete of the present invention advantageously reduces drying shrinkage, improve cracking resistance, significantly reduce concrete shrinkage and cracking sensitivity, by controlling concrete component mass ratio each other, can effectively adjust concrete shrinkage change, improve its cracking resistance.
Description
Technical field
The present invention relates to the cement-base composite material of building material field, specifically one and improve cement slurry hole
The enhancement mode anti-crack concrete of structure and homogeneity.
Background technology
Engineering cracks has become the focal issue in construction, and wherein the crack problem of mass concrete is particularly subject to close
Note.The factor affecting cracking of reinforced concrete is divided into internal factor and external factor.For larger-size flat board thicker large volume
Concrete (general thickness more than 1m, size at about 100m, hereinafter referred to as large-area backplane concrete) for, affect its cracking resistance
The self performance that key factor is concrete of property and foundation restriction power.Large-area backplane xoncrete structure is thicker due to thickness,
Being easily formed internal-external temperature difference during hydration reaction, produce temperature stress, especially it is relatively big by ground and internal reinforced binding,
Easily form bigger shrinkage stress and ftracture, the crack resistance of concrete is required the highest.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of enhancement mode anti-crack concrete, and it is special
Levy and be: include corundum, sodium bentonite, coarse aggregate, fine aggregate, rubber grain, polystyrene foam particles, breeze and cunning
Stone, its feed components is by weight, described corundum 80-100 part, sodium bentonite 30-35 part, coarse aggregate 45-51 part, thin
Aggregate 37-47 part, rubber grain 10-20 part, polystyrene foam particles 10-15 part, breeze 30-40 part and Talcum 20-25 part.
As preferably, described enhancement mode anti-crack concrete, it is characterized in that: its feed components by weight, comprises gold
Emery 80 parts, sodium bentonite 30 parts, coarse aggregate 45 parts, fine aggregate 37 parts, rubber grain 10 parts, polystyrene foam particles 10
Part, breeze 30 parts and 20 parts of Talcum.
As preferably, described enhancement mode anti-crack concrete, it is characterized in that being prepared by following method:
(1) good various raw materials are configured by weight ratio；
(2) the various raw materials configured are added in stirred reactor one by one, be evacuated to 0.2MPa, at rotating speed be
Stir 2h under conditions of 60rpm, can be prepared by enhancement mode anti-crack concrete.
The corundum used in concrete of the present invention advantageously reduces drying shrinkage, improves cracking resistance, significantly reduces mixed
Solidifying soil drying shrinkage and cracking sensitivity, by controlling concrete component mass ratio each other, can effectively adjust concrete dry
Contracting change, improves its cracking resistance.

Granule 10-20 part, polystyrene foam particles 10-15 part, breeze 30-40 part and Talcum 20-25 part.
As preferably, described enhancement mode anti-crack concrete, it is characterized in that: its feed components by weight, comprises gold
Emery 80 parts, sodium bentonite 30 parts, coarse aggregate 45 parts, fine aggregate 37 parts, rubber grain 10 parts, polystyrene foam particles 10
Part, breeze 30 parts and 20 parts of Talcum.
As preferably, described enhancement mode anti-crack concrete, it is characterized in that being prepared by following method:
(1) good various raw materials are configured by weight ratio；
(2) the various raw materials configured are added in stirred reactor one by one, be evacuated to 0.2MPa, at rotating speed be
Stir 2h under conditions of 60rpm, can be prepared by enhancement mode anti-crack concrete.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and
Modification, these improve and modification also should be regarded as protection scope of the present invention.
