摘要
研究了白云石的煅烧温度、保温时间以及掺量等对水泥物理性能和膨胀行为的影响规律。研究发现，合理控制白云石的煅烧温度、保温时间，选择合适的掺量，可以使水泥浆体产生适度的膨胀，起到补偿收缩、防止开裂、增加强度、提高抗渗性能等作用。
In this paper, the effects of calcination temperature, holding time and content of dolomite on the strength and expansion rate of cement mixed with calcined dolomite are investigated. The results show that having reasonable control of calcination temperature, holding time and content of dolomite, we can make the hardened cement paste have suitable expansion, and play a role of compensate shrinkage of the paste, reinforcement and improving impermeability.
