2用于夏秋季节施工和大面积滑模施工。调节掺量，可有效地控制砼的凝结时间，掺量可调范围大，塌落度损失小。 - According to many years experience of dealing with client quality complains , the author introduced in brief its principle and content , and laid emphsis on the common quality complains of cement enterprise , such as concrete strength is lack , the concrete setting time is unnormal , the concrete slump constant is a little small and the loss is high , compatibility between cement and admixture is bad , cement color changes , concrete surface rise sand and cement agglomerate
作者结合自己多年处理顾客质量投诉的经验，简单介绍了处理顾客质量投诉的调查原则和内容；重点对水泥厂最常见的质量投诉内容包括混凝土强度不足，凝结时间异常；混凝土坍落度偏小，经时损失大；水泥与外加剂相容性不好；水泥颜色变化、混凝土地面起砂及水泥结块等等投诉，分别进行了现象描述，原因分析和调查方法介绍。 - The relation between addition content of calcined kaolin , aluminium powders and aluminum sulfate in concrete and compressive strength , slump constant , 30min slump and permeability altitude were studied , and according to the experiment results , the component percent contents of crack - resistant and water - repellent admixture in cement were determined as following : calcined kaolin 6 % , aluminum sulfate 4 % and aluminium powders 0 . 005 %
通过对煅烧高岭土、铝粉、硫酸铝在混凝土中掺量对其抗压强度、初始武汉理工大学硕士学位论文坍落度、 3omin坍落度保留值及透水高度的影响，确定了配制抗裂防水外加剂的各组成成分以其占水泥质量的百分比分别为:锻烧高岭土6 % ，硫酸铝4 % ，铝粉为0 . 005 % 。
