Abstract
The invention relates to the field of concrete production, in particular to a concrete grinding aid. The concrete grinding aid is prepared from, by mass, 10-18 parts of propylene glycol, 10-15 parts of triisopropanolamine, 3-5 parts of unsaturated polyester resin, 2-8 parts of calcium formate, 3-5 parts of carboxymethylcellulose, 10-30 parts of maleic anhydride, 2-6 parts of nanosilicon dioxide, 2.4-5.6 parts of sodium hexametaphosphate, 2-6 parts of APEG, 1.8-4.8 parts of water retention cellulose and 50-60 parts of water. On the condition that the state of a mill is not changed, the yield of the mill can be improved by 10-30%, meanwhile, the excessive grinding phenomenon can be effectively reduced, and the concrete grain composition is optimized; the dispersity of materials in the mill can be improved, and the concrete fine particle electrostatic adsorption and ball wrapping and mill burning phenomena can be effectively eliminated.
Description
Technical field
The present invention relates to concrete production field, especially a kind of concrete grinding aid.
Background technology
Concrete grinding aid is a kind of chemical addition agent improving cement grinding effect and performance, can significantly carry
High concrete yield, each age concrete intensity, improve its mobility.Concrete grinding aid can significantly drop
The Electrostatic Absorption bag ball phenomenon formed in low grinding process, it is possible to reduce ultra-fine formed in grinding process
The coalescence trend again of grain.Concrete grinding aid also can significantly improve concrete flowability, improves grinding of grinding machine
Mill effect and the grinding efficiency of powder concentrator, thus reduce grinding energy.Use the concrete tool that grinding aid produces
There is relatively low compacting coalescence trend, thus the handling of beneficially concrete, and the wall built-up that can reduce concrete is existing
As.As a kind of chemical addition agent, grinding aid can improve concrete particle and is distributed and excites aquation power, from
And improve early age strength of concrete and later strength.
Domestic most employing technical pure polymerization organic salt and inorganic salt are the main component of grinding aid, relatively costly,
Technical-economic index is not suitable with practical condition, and product adaptation face is narrower, especially for the thing that temperature is higher
Material does not also have suitable product.Identical product even for different manufacturers is applied to different manufacturers, also
There is the situation that difference on effect is bigger.Existing product cannot give full play to this product and improve grinding material adhesion effect
Really, and fail by multiple effective grinding aid components matching together, thus play optimal grinding effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome deficiency of the prior art, it is provided that a kind of good water-retaining property,
The concrete grinding aid of cement specific surface area and outward appearance can be improved.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows:
A kind of concrete grinding aid, its mass parts composition is as follows: propylene glycol 10-18 part, triisopropanolamine 10-15
