在国内建筑工程中使用减水剂的实践说明,减水剂的使用效果,常随所用水泥的矿物组成不同而有差异。把握住不同种类减水剂对不同组成水泥的适应性,是施工单位的现实要求。在我国研制和应用减水剂的时间不长,推广面还不很广,经验未免不足。而我国水泥组成的差异较大。首先大部分水泥中掺有混合材料;第二是生产水泥用熟料的矿物组成含量有较大变化;第三是生产熟料的窑型
The practice of using water-reducing agents in domestic construction projects shows that the effect of water-reducing agents often varies depending on the mineral composition of the cement used. Grasping the adaptability of different types of water-reducing agents to different compositions of cement is a practical requirement of construction units. The development and application of water-reducing agents in our country is not long, the promotion is not very wide, and the experience is not enough. However, the composition of cement in China is quite different. First of all, most of the cement is mixed with mixed materials; the second is that there is a big change in the mineral composition of the clinker used to produce cement; and the third is the kiln type that produces clinker.
