水泥砂浆地面起砂是建筑工程质量“通病”之一,也是大家比较关注的问题。山东省军区后勤部自1981年开始研究用元砂细石混凝上楼地面解决水泥砂浆地面起砂的做法,经多年实践应用,效果良好。这种做法不起砂,不空鼓,可磨性好,抗压强度高,比砂浆地面提高一倍,每平方厘米可达到200公斤,造价还可降低10%左右。现将无砂细石混凝 The sanding of cement mortar on the ground is one of the “quality problems” in construction projects and is also a matter of concern to everyone. Since 1981, the Logistics Department of the Shandong Military District began to study the practice of using sand and fine aggregates to settling floors to solve the sanding of cement mortar. After many years of practical application, the results have been good. This practice can not sand, not hollowing, good grindability, high compressive strength, double the mortar floor, can reach 200 kilograms per square centimeter, the cost can be reduced by about 10%. There will be no sandstone coagulation
