石灰绿页岩水泥是一种经济有效的新品种水泥,它是由煅烧的和不煅烧的绿页岩、石灰和石膏按一定的比例一同磨细而成.制造这种水泥不但生产过程简单,所需设备不多,成本较低,而且质量很好,原料未经热处理制得的水泥标号为150-200号,原料经热处理制得的水泥标号介于300-400号之间.此外,这种水泥还具有在潮湿环境中后期强度增长率较大和适于一般蒸汽养护的优点.所以利用绿页岩生产石灰绿页岩水泥,在目前实有莫大的意义. 1、原料的选择及其性能
Lime-green shale cement is a new kind of economical and effective cement. It is made from calcined and non-calcined green shale, lime and gypsum in a certain proportion and ground together. This cement is not only simple in production process, but also The required equipment is not much, the cost is low, and the quality is very good. The cement with the raw material without heat treatment is numbered 150-200, and the cement code of the raw material after heat treatment is between 300-400. In addition, this This type of cement also has the advantage of greater late growth rate of strength in the humid environment and is suitable for general steam curing. Therefore, the use of green shale to produce lime-green shale cement is of great significance at present. 1. Selection and performance of raw materials
