在石灰境粘土水泥的生产中,水泥安定性的好坏是衡量生产工艺和水泥质量的重要标志之一。由于石灰烧粘土水泥硬化缓慢,有的凝结时间也比较长,成型的试验在养护箱养护24小时后,还没有足够的强度,甚至有的终凝还没有到,因此要经过养护7天,有一定的强度后,才能进行蒸煮试验。如果能把检验的时间缩短,提早测知水泥安定性,对石灰烧粘土水泥的生产,有着极为重要的意义。我们本着缩短养护时间这个方向,进行了用蒸汽养护试饼的研究试验工作,以便能更快地测出石灰烧
In the production of clay cement in lime, the stability of the cement is one of the important indicators to measure the quality of the production process and cement. Due to the slow hardening of lime-fired clay cement, some of the coagulation time is relatively long. After 24 hours of maintenance, the molding test has not yet had enough strength, and even some final coagulation has not yet arrived. Therefore, after 7 days of conservation, there are Only after a certain intensity can cooking test be conducted. If we can shorten the inspection time, we can know the stability of cement in advance and have a very important significance for the production of lime-fired clay cement. In the direction of shortening conservation time, we conducted research and trials on the maintenance of test cakes with steam so that lime burns can be measured more quickly.
