摘要
研究了磷渣对水泥浆体孔结构和抗压强度的影响。结果表明,与纯水泥浆体的孔结构相比,磷渣的掺入使浆体早期的孔隙率增大,大孔所占的比例增加,但降低了浆体后期的孔隙率和孔径尺寸。浆体早期的抗压强度随磷渣掺量的增加而减少,90d时,其强度超过了纯水泥浆体。
Effects of phosphorus slag on strength and pore structure of cement paste were studied, The results showed that, with the phosphorus slag mixed in cement, the early porosity of cement pastes was increased, while late porosity was decreased, and pore size distribution was also changed, The compressive strengths at 3, 7 and 28 days decrease with the increase of phosphorus slag replacement, but at 90 days, all the compressive strengths exceeded that of pure cement paste.
