轻烧白云石对硅酸盐水泥性能的影响研究

将一定煅烧制度下所得的轻烧白云石掺入硅酸盐水泥，研究了轻烧白云石对水泥物理、力学性能的影响，同时采用XRD，DTA对水泥的水化性能进行了研究。将掺入轻烧白云石水泥的力学性能与掺入活性氧化镁、石灰石以及白云石水泥的力学性能进行了对比后发现，轻烧白云石的掺入使得水泥能够获得比掺活性氧化镁和石灰石粉更好的力学性能，也显示了优于掺入白云石后水泥的力学性能。

Effect of Light-burnt Dolomite on Performance of Portland Cement

The light-burnt dolomite was obtained according to controlling the calcining system and mixed into Portland cement, result in a cementitious material. The basic physical performance and mechanics performance of the cementitious material has been studied, and the hydrated performance of Portland cement was investigated by X-ray diffraction and DTA methods. At the same time, light-burnt dolomite was compared with active magnesia, limestone and dolomite as the admixture of cement. The results indicated that the strength of cementitious material including light-burnt dolomite was better than the strength of cementitious material including active magnesia and limestone, and superior to the strength of cement adding dolomite.
