Effect of Contrast Cement on the Performance Test of GBFS Powder
摘要 采用不同的对比水泥对矿渣粉的活性指数、流动度比和凝结时间比等物理性能进行了测定,研究了对比水泥的抗压强度、比表面积、碱含量以及混合材的种类和掺量对矿渣粉性能检测结果的影响规律,并探讨了粒化高炉矿渣粉对比水泥技术指标的适宜范围。结果表明,对比水泥的混合材掺量、碱含量、比表面积、凝结时间和抗压强度对矿渣粉的活性指数、流动度比以及凝结时间比等指标检测结果影响显著;本试验研究建议将GB/T 18046-2008标准中对比水泥的比表面积修改为“350~400m2 /kg”,同时增加3d抗压强度为“25~35MPa”,更符合矿渣粉物理性能检测的需要。
