Abstract
The invention relates to a high-efficiency energy-saving concrete which comprises the following raw materials in parts by weight: 100-120 parts of cement, 22-40 parts of pitchstone sand, 18-26 parts of aluminum sulfate, 15-18 parts of high efficiency water reducing agent, 30-40 parts of ore powder, 8-12 parts of calcium sulfate and 20-22 parts of talcum. The limiting strain capacity of the concrete can be enhanced, thereby greatly enhancing the crack resistance of the concrete, lowering the cement consumption, saving the energy consumption and lowering the production cost.
Description
Technical field
The present invention relates to the cement-base composite material of building material field, specifically one and improve cement slurry hole
Structure and the energy-efficient concrete of 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 energy-efficient concrete, its feature
It is: including cement, pitchstone ore in sand form, aluminum sulfate, high efficiency water reducing agent, breeze, calcium sulfate and Talcum, its feed components is by weight
Meter, described cement 100-120 part, pitchstone ore in sand form 22-40 part, aluminum sulfate 18-26 part, high efficiency water reducing agent 15-18 part, breeze
30-40 part, calcium sulfate 8-12 part and Talcum 20-22 part.
As preferably, described energy-efficient concrete, it is characterized in that: its feed components by weight, comprises cement
100 parts, 22 parts of pitchstone ore in sand form, 18 parts of aluminum sulfate, high efficiency water reducing agent 15 parts, breeze 30 parts, 8 parts of calcium sulfate and 20 parts of Talcum.
As preferably, described energy-efficient concrete, it is characterized in that: the solid content of described high efficiency water reducing agent mother solution is
30%。
As preferably, described energy-efficient 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, be 60rpm at rotating speed
Under conditions of stir 2h, can be prepared by energy-efficient concrete.
The present invention can improve the ability of concrete limiting strain, thus is greatly improved concrete capacity against cracking, reduces water
Mud consumption, energy efficient, reduces production cost.
