Present invention also offers the preparation method of above-mentioned composite cement grinding aid, it is characterised in that claim in proportion
Take each component, mix, stir.
Present invention also offers the application in cement production process of the above-mentioned composite cement grinding aid.Its feature
Be directly by composite cement grinding aid in the way of spraying, be uniformly sprayed into cement mill, composite cement
Using quality is the 0.04~0.08% of cement quality to be ground.
The raw material of the present invention also can be used directly glycerine, lignin and molasses commercially available, and weight portion is slightly adjusted
Whole.
Beneficial effect:
1. this grinding aid is remarkably improved cement grinding efficiency, and cement granules grating is optimized.Help with not filling
The cement of grinding agent is compared, and under the conditions of equal grinding, 3~32 μm grain volume fractions add more than 4.6%;
Specific surface area adds 14m2/ more than kg.
2. this grinding aid reduces consumptive use of water normal consistence, improves early stage and the later strength of cement, and stable
Property and setting time uninfluenced, with reference to compared with sample, cement 3d compression strength improves more than 16.1%,
28d compression strength improves more than 19.2%.
3., there is not lamination in this grinding aid steady quality, at ambient temperature long-term storage.
Detailed description of the invention
Cement component to be ground used in embodiment, in mass ratio meter are as follows: grog 80%, flyash 10%, slag
5%, gypsum 5%.Take in the standard test ball mill that 5kg cement to be ground is placed in Φ 500mm × 500mm, will claim
