地面硬化剂施工方案及保护措施Construction concept for floor hardener1）、硬化地面对新浇混凝土的要求Requirement for the concrete floor金属耐磨地坪是在新浇混凝土初凝后开始施工，按顺序进行，因此新浇混凝土的施工质量直接影响着金刚砂耐磨地坪面层的质量。金属耐磨地坪对新浇混凝土的要求为：Start metallic floor after concrete primary congealment, the concrete grouting quality will be directly affect the quality of emery wearability floor, so the requirement for the concrete grouting is:1. 为防止地坪空鼓，基底表层应清理洁净，去除浮浆、油渍；基底需用水湿润。To prevent hollow floor, clean off the float slurry and greases on the base layer, wet the base layer.2. 基层混凝土标号应不小于 C20。The concrete class of the base layer shall not be less than C20。3. 应控制好混凝土的水灰比，金属地坪的混凝土水灰以不大于 0.5为宜。Control the concrete water cement ratio, the ratio of concrete floor shall not be bigger than 0.5 as well.4. 新浇混凝土选用商品砼时其坍落度应控制在 12-14cm 之间。The slump of the ready-mixed concrete shall be controlled between 12cm and 14cm 5. 新浇混凝土骨料的含泥量应控制在 1%以内，最大骨料粒径控制在 3cm 以内。The mud rate in the concrete aggregate shall be controlled within 1%, the maximum diameter of stones shall be less than 3cm.6. 新浇混凝土宜用平板振动器或用钢制辊筒捣实，在无法用辊筒压实的部位，可先用木蟹拍实，再用长靠尺刮平找平，新浇混凝土捣实后应及时对其面层水平进行控制，对偏差部位加以调整，新浇混凝土面层平整度应控制在 4mm 以内。It is better to use flat type vibrator or steel roller for concrete surface leveling. Use wood plate to compact the concrete where can not be rolled, level the surface with long wood strips. The concrete surface level error shall be controlled within 4mm. 7. 混凝土面多余的泌水应及时除去，施工时可以用皮管吸去多余泌水，亦可用海绵吸取、转移多余泌水。.Get rid o...
