摘　　要：通过试验,研究了制浆造纸白泥用作白色硅酸盐水泥混合材的工作性能和力学性能,并分析了其对水泥水化产物及微观结构的影响。结果表明,制浆造纸白泥白度高(94.55),比表面积大,其主要矿物相为碳酸钙;适量掺入白水泥中可显著提高其白度。The working properties and mechanical properties of white Portland cement that using lime mud from paper mill as admixture were discussed, and the hydration products and mierostrueture of cement were also studied. The results showed that the calcium carbonate was the main mineral phase of lime mud from paper mill. The higher white degree （94.55） and specific surface area of the lime mud could significantly improve the whiteness of the white cement.
