缩短水泥砂浆和砼的硬化过程,具有很大的益处。为了掌握这个新方法,我们曾按法国人研究后的资料(1),进行研究。这个方法采用结晶的“胚”作为掺料,这种掺料是将初期硬化了的水泥石磨细而得到的。在研究掺料的过程中,制备如下的样品:用标准稠度的水泥浆,在湿润的条件下,温变为20℃时,经过第一昼夜的硬化,此后,把这些硬化了的水泥浆打成小块,并在35℃的温度下,于空气中保养经历5昼 Shorten the hardening process of cement mortar and concrete, with great benefits. In order to grasp this new method, we conducted the research according to the French study (1). This method uses crystallized “embryos” as the spice, which is obtained by grinding the initially hardened cement stone. During the study of the spice, samples were prepared which were hardened with a standard consistency grout under wet conditions for a first day and night when the temperature was changed to 20 ° C. Thereafter, the hardened grout was rated as Small, and at 35 ℃ temperature, in the air for 5 days of maintenance
