二、混合材料对水泥性能的影响(一) 一般物理性能的影响1,正則稠度混合材料比重一般在2.60～2.65间,而水泥則在3.1左右。細度一致时,單位重量白土顆粒比水泥数多,表面积大,需水量大。尤其是燒粘土磨细后,本身吸水性甚强,在熟料水泥中摻入35%,將增加5～10%的正則加水量(見表10),但对水泥泌水性却有了改善。2.凝結时間水泥全部水化仅需其本身重量的15～20%的加水量,而其余絕大部分水量是为了满足混
Second, the impact of mixed materials on the performance of the cement (a) the impact of general physical properties 1, the proportion of regular consistency of mixed materials generally 2.60 ~ 2.65, while the cement is about 3.1. The same degree of fineness, the unit weight of clay particles than the number of more surface area, water demand. In particular, the burned clay itself has a very strong water absorption. Incorporating 35% of the clinker cement increases the regular water addition of 5 to 10% (Table 10), but improves the bleeding of the cement. 2. Setting time All hydration of cement requires only 15% to 20% of its own weight of water, while most of the rest of the water is to meet the mixed
