改性硅酸盐复合水泥早期力学性能的初探及机理分析

Early age mechanical properties of modified composite cement and its mechanism

通过设计正交试验探索掺磷铝酸盐水泥的改性硅酸盐复合水泥的力学性能,从石膏、磷铝酸盐水泥熟料、外加剂等因素调控,以改性后的硅酸盐复合水泥水化浆体的早期抗压强度为主要指标确定最佳方案,并与未改性的硅酸盐水泥强度作对比,并通过数据分析及XRD、SEM、孔结构分析等现代测试手段,解释改性硅酸盐复合水泥早期力学性能得以改善的机理。

To explain the mechanism of improving early strength of modified composite Portland cement, changing the content of gypsum, phosphoaluminate cement, and some additives, with orthogonal experience, and XRD, SEM, pore structure analysis etc., the preliminary result had been obtained.
