Experimental study on effect of mineral composition of clinker on properties of Portland cement.

This paper mainly studies the influence of clinker mineral composition on the performance (flow variability and expansion performance, hole structure, etc.) of silicate cement. The experimental results show that the shear stress of silicate cement slurry body consisting of different minerals is different with the rheography curve of shear rate, and the linear relationship between the two belongs to Bingham rhesino equation, the expansion rate is also quite different, the expansion rate of D mineral composition is the largest, and the distribution of the aperture of different minerals composition is different, the size of the gap and the degree of hydracy are different.
