The Influence of Steel Slag on Phosphorous Slag Cement
In this paper, the influence of steel slag and its pretreatment method on properties of phosphorus slag cement has been studied. The hydration process and microstructure were studied by X-ray diffraction (XRD) and scanning electronic microscopy (SEM). Results show that, the problem of long setting time of high content phosphorous slag cement can be effectively solved by adding steel slag and pretreated steel slag. About 6% content of steel slag could promote the early hydration of phosphorus slag cement and reduced the initial setting time 2 hours. Grinding phosphorous slag and steel slag with different water content, the initial set time of phosphorus slag cement for 6 hours has reduced to 2.5 hours without changing the strength. Ageing the mixed grinding power of phosphorous slag and steel slag and keeping 2.5 hours of the initial set time, the early cement strength can increase 3 MPa.
