Construction process of misfire fine aggregate concrete ground polishing
The invention provides a construction process of a misfire fine aggregate concrete polished floor, which is characterized in that coarse aggregate in surface layer fine aggregate concrete is in continuous grading with the grain size of 8-12mm, the fine aggregate is II-area medium sand, surface layer pouring is implemented before initial setting of base layer concrete is completed, a base layer and the surface layer are subjected to continuous pouring construction, and polishing treatment is performed after the surface layer concrete reaches a certain strength. Compared with a traditional misfire terrazzo floor construction technology, the method has the advantages that the separation strip mounting procedure is omitted, follow-up construction can be carried out without waiting for certain strength of base concrete solidification and separation strip mortar curing solidification, extra interface treatment does not need to be carried out on the base surface, the construction time is greatly shortened, and the construction period is shortened by about 45%; the surface layer is poured before initial setting of base layer concrete, the surface layer is made of continuous grading concrete and is evenly vibrated through a flat plate vibrator, construction cold joints between the surface layer and the base layer and shrinkage, hollowing and cracks of the surface layer are avoided, and the overall strength of the ground is improved by about 15%.
本发明提供一种不发火细石混凝土磨光地面施工工艺，面层细石混凝土中粗骨料粒径为8mm～12mm连续级配，细骨料为Ⅱ区中砂，在基层混凝土完成初凝前实施面层的浇筑，基层和面层连续浇筑施工，面层混凝土达到一定强度后进行磨光处理。本发明的优势在于：取消了分隔条安装工序，与传统不发火水磨石地面施工工艺相比无需等待基层混凝土凝固和分隔条砂浆养护凝固有一定强度才展开后续施工，不用对基层表面进行额外界面处理，大大缩减了施工时间，工期缩短约45％；在基层混凝土初凝前浇筑面层，且面层采用连续级配混凝土，用平板振捣器均匀振捣，避免了面层与基层之间的施工冷缝和面层的收缩、空鼓、裂缝，提高了地面整体强度约15％。
