制备了CaO-Al_2 O_3-SiO_2系统的仿矿渣玻璃。在石膏和石灰的体系中，特别是在过量石膏体系中，测定了它们的放热速率。它们有一个放热速率恒定的周期。这些速率取决于玻璃的成分。讨论了各组分对玻璃放热速率的影响，玻璃的恒放热速率取决于玻璃的组成，特别是CaO和Al_2O_3的含量。该过程的时间由石灰添加量控制。在该阶段期间，固体Ca（OH）（2）被完全消耗。在这个硫酸盐过量的系统中，在Ca（OH）（2）消耗期间，反应方程式应写作：玻璃+石膏+石灰双右箭头C-S-H，C/S比为1.42，钙矾石。(c)2005爱思唯尔有限公司保留所有权利。
Slag-simulated glasses in the system of CaO-Al2O3-SiO2 were prepared. Their rates of heat liberation were measured in the system with gypsum and lime, especially in the excess gypsum system. They have a period with constant rate of heat liberation. These rates depend on the components of the glass. The effects of the components on the rate of heat liberation were discussed.The rates of constant heat liberation depend on the composition of glass especially the contents of CaO and Al2O3. The period of this process was controlled by the amount of lime addition. During this stage, the solid Ca(OH)(2) was completely consumed. In this sulfate-excess system, the reaction equation, during Ca(OH)(2) consumption, should be written as; glass + gypsum + lime double right arrow C-S-H with a C/S ratio of 1.42 and Ettringite.
