摘要
分析了水泥基材料收缩的特点,研究了钙矾石系膨胀剂与轻烧MgO膨胀剂的膨胀特点及二者之间的区别,探讨了膨胀剂补偿收缩作用及膨胀剂的适应性。
The expansive characteristics of ettringite and magnesia calcined at low temperature are investigated on the basis of the analysis of swelling nature of cement-based materials. The shrinkage compensating effect and the adaptability of these two expansive agents are discussed.
