采用MgO和KH2PO4制备磷酸镁水泥,研究使用钢铁渣粉改性磷酸镁水泥的凝结时间和强度,发现随钢铁渣粉掺量增大,磷酸镁水泥的凝结时间逐渐延长;掺量在20%以内的钢铁渣粉对强度有增益效果,超过20%则强度下降.%The test use MgO and KH2PO4 making of magnesium phosphate cement, and use the steel slag powder on cement modification research. The setting time and strength of modified MPC are studied. The study found that with the increase of dosage of steel slag powder, magnesium phosphate cement setting time extended gradually; Content within 20% steel slag powder has gain the effect to the strength, strength of more than 20% decline.
