一、选好原材料水泥地面所使用的原材料是保证工程质量的前提,因此,施工前必须严格选材。使用普通硅酸盐水泥,强度等级不应低于 M32.5,刚出窑的、过期或受潮结块的水泥不得使用。宜用中粗砂,含泥量不大于3%。用于面层的豆石和碎石粒径不应大于15mm,也不应大于面层厚度的2/3,含泥量不大于2%。
First, the selection of raw materials The raw materials used on the cement floor is to ensure the quality of the project premise, therefore, must be strictly selected before construction. Use ordinary Portland cement, the strength level should not be less than M32.5, just out of the kiln, expired or damp agglomeration of cement shall not be used. Should be used in coarse sand, clay content of not more than 3%. For the surface of the beans and gravel diameter should not be greater than 15mm, nor greater than 2/3 the thickness of the surface layer, mud content of not more than 2%.
