Abstract
In this paper, By choosing four kinds of grinding aids better one-component, The grinding aid of cement grinding aids is determined by orthogonal optimization. By adding different inorganic reinforcing components, Developed a cement grinding aids.The result turns out, compared with blank sample, the adulteration of grinding aid leads compression strength of 3d, 7d and 28d respectively are improved 17.9%, 17.8% and 16.8%，cement fineness to reduce by 63.1% and specific surface area to increase about 10.6%. Meanwhile, cement particles ranging 3-32 μm is improved 11.3%, which optimizes the grain composition of cement and increases strength of cement. The experimental research to provide technical support for the future development of cement technology.
