Description
Technical field
The invention belongs to silicate material technical fields, more particularly to a kind of modified concrete and preparation method thereof.
Background technique
Concrete, referred to as " concrete (t ó ng) "：Refer to the cementing integral engineered composite material of aggregate by cementitious material
General designation.One word of concrete usually said, which refers to, makees cementitious material, sand, masonry aggregate with cement；With water (additive can be contained and mixed
Close material) cooperate by a certain percentage, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in building work
Journey.
The inorganic coagulation materials such as cement, lime, gypsum and water, which mix and stir, makes concrete mix have plasticity；And then pass through
Chemically and physically chemical action condensation is hardened and degree of generation.It is, in general, that drinking water can all meet wanting for concrete mixing water
It asks.Excessive acid, alkali, salt and organic matter all can generate harmful influence to concrete in water.Aggregate not only has filling effect, and
And the properties such as the bulk density to concrete, intensity and deformation have a major impact.For the certain properties for improving concrete, can be added additional
Agent.There is apparent techno-economic effect due to mixing additive, it has become the indispensable component of concrete.
The performance of concrete, saves cement after workability or hardening to improve concrete mix, stirs in concrete
When can also mix levigate mineral material.It is divided into active and inactive two class.The property and quantity of admixture, influence concrete
Intensity, deformation, the heat of hydration, impermeability and color etc..
Summary of the invention
The purpose of the present invention is to provide a kind of modified concrete and preparation method thereof, by aggregate, cement, flyash,
Reasonably combined and preparation method the optimization of additive, water and silicon powder, solving existing concrete, there are tensile strength and splitting
The low problem of intensity.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
