在“石灰烧粘土水泥生产工艺上的几个问题”一文中就已谈到,要控制好无熟料水泥的质量,必须在生产中经常进行物理性能的检验.如按标准的检验方法进行检验是需要整套试验设备(如锤击机、拉力机、压力机等)的,这在目前农村还不可能办到,因此,我们设计了一种既简单方便,又有一定程度准确性的简易测定法.但由于我们对这种简易方法进行研究的时间很短,所做的试验也不多,所以希望各地在 In the article “Several Issues on the Production Process of Lime-fired Clay Cement”, it has been mentioned that to control the quality of cement without clinker, it is necessary to conduct physical property tests in production. If the inspection is conducted according to the standard inspection method It is necessary to use a complete set of test equipment (such as percussion machines, tension machines, presses, etc.), which is not yet possible in rural areas. Therefore, we have designed a simple and convenient method with a certain degree of accuracy. However, due to the short time of our research on this simple method and the few tests done, we hope that
