Construction method for reducing internal cracking of mass concrete
The invention discloses a construction method for reducing internal cracking of mass concrete, which aims at internal cracking caused by temperature difference, and comprises the following steps: primary pouring: adding a retarder into concrete, and pouring a first layer of concrete; secondary pouring is conducted, specifically, pouring of a second layer of concrete is conducted without adding the retarder and the coagulant into the concrete; finally, the concrete is initially set to form the concrete bottom plate. The method has the beneficial effects that the retarder and the coagulant are added into the interlayers, so that the adjacent layers are simultaneously coagulated, the adjacent layers synchronously release heat to reduce the temperature difference of adjacent parts, the temperature difference in the mass concrete is reduced by the method, and the performance of the mass concrete is improved.
本发明公开了一种针对内部因温度差造成开裂的降低大体积混凝土内部开裂的施工方法，包括如下步骤：一次浇筑：在混凝土中加入缓凝剂，进行第一层混凝土的浇筑；二次浇筑：在混凝土中不加入缓凝剂和促凝剂，进行第二层混凝土的浇筑；最终混凝土初凝形成混凝土底板。本发明的有益效果：通过隔层加入缓凝剂和促凝剂的方法，以达到相邻层同时凝结，达到相邻层同步放热以减少临近部位的温度差，以此方法降低大体积混凝土内部温差，从而提高大体积混凝土的性能。
