摘　　要：水下灌注混凝土与普通灌注不同,因在水下不具备振捣条件,而靠混凝土自身压力产生流动进行密实,施工较普通混凝土困难。所以要求混凝土必须具有良好的和易性,即富有粘性,较大的流动性和一定的保水能力。做好混凝土配合比工作,通过试验合理选用水泥用量,用水量,砂率,骨料的最大粒径与级配,确保其具有较好的和易性和流动性。The underwater concreting and general perfusion different, because in the water does not have the vibration conditions, the pressure generated by the flow of the concrete itself dense than ordinary concrete construction difficulties. So they requested that the concrete must have good workability, is rich viscosity, greater mobility and a certain water--retention capacity. Make concrete mix to work through trial and reasonable amount of cement used, water, sand ratio, the maximum aggregate size and gradation, ensure that it has good workability and mobility.
