炉渣混凝土垫层楼地面以其材料来源广、造价低、自重轻、作法简便、隔音效果明显,在民用建筑中广泛采用。但如果材料选择不妥、施工操作不当就容易出现裂纹、空鼓、起皮、起砂等问题。新疆军区某部近几年来建设的五万多平方米各类营房,普遍采用炉渣混凝土垫层楼地面,极少发现上述弊病,交付使用后基本无变化,并且越磨越光、越磨越亮,使用单位反映很好。其作法是: 1.材料选用。①水泥采用325号普通硅酸盐水泥。②炉渣粒径不大于炉渣混凝土垫层厚度的1/2,3mm以下的粉末不能超过30％,并不得有碎砖、
The slag concrete cushion floor is widely used in civil buildings due to its wide source of materials, low cost, light weight, easy operation and sound insulation. However, if the materials are not properly selected and improperly constructed, problems such as cracks, emptying, peeling, and sanding can easily occur. A 50,000-square-meter square barracks built by a department of the Xinjiang Military Command in recent years has generally used slag-concrete floor coverings. The above-mentioned shortcomings are rarely found, and there are basically no changes after delivery, and the more they wear out, the more they wear brighter. The use of units reflects well. Its practice is: 1. Material selection. 1 Cement uses No. 325 ordinary Portland cement. 2 The particle size of the slag shall not be greater than 1/2 of the thickness of the slag concrete cushion, and the powder below 3mm shall not exceed 30%, and no broken bricks shall be allowed.
