Abstract
The invention discloses a reinforced cement grinding aid and cement thereof, belonging to the field of cement manufacturing. The cement grinding aid is prepared from the following raw materials in parts by weight: 4-8 parts of hydroxyethyl diethylene triamine, 4-10 parts of triethanolamine, 1-5 parts of calcium formate, 1-5 parts of UPR (unsaturated polyester resin), 4-10 parts of diethylene glycol amine, 4-10 parts of ligninsulfonate, 4-10 parts of sodium thiosulfate, 3-9 parts of sodium gluconate, 2-8 parts of molasses and 4-8 parts of glycerinum. The invention further discloses cement comprising the reinforced cement grinding aid. The reinforced cement grinding aid is low in doping quantity, has a good reinforcement effect, the performance and machine-hour output of cement can be increased, the production cost of the cement can be lowered, the cement produced by adopting the grinding aid has less clinker proportion, the production cost is low, the environment pollution can be decreased, and the mineral resources can be saved.
Description
Technical field
The present invention relates to a kind of enhanced cement grinding aid and cement thereof, belong to cement and manufacture field.
Background technology
Cement is indispensable a kind of construction material in human lives and social production, and its range is wide, and consumption is big,
Have " title of the grain of building industry ".But, cement production industry is polluted big, and energy resource consumption is big.In order to energy-saving and cost-reducing, most preferably
Approach is exactly interpolation cement grinding aid in grinding process, on the one hand, cement grinding aid produces when can improve the platform of cement mill
Amount, thus directly reduce grinding pow consumption；On the other hand, cement grinding aid can also excite the activity of industrial residue, reduces water
The usage amount of mud grog, thus save coal, the electric consumption caused because producing clinker, and reduce atmosphere pollution
Discharge, improves the utilization ratio of industrial residue so that it is resource efficiency improves, and while realizing " energy-conservation " effect, also reaches
Arrive the purpose of " reduction of discharging ".
The component that at present China's grinding aid product the most generally exists is single, with high costs, constant product quality is poor, right
The best popularization and application waiting defective effect grinding aid of process conditions adaptability, therefore need badly by experimental study, develop a class tool
Standby grinding-aid effect is excellent, with low cost, properties of product are stable, high the having concurrently of universality is improved cement physical properties, excited mixing material
Activity, the multi-functional composite grinding aids of raising blending amount of mixture material.
