新型水下混凝土抗分散剂的性能研究

根据水下混凝土施工的需求研制出一种新型JS水下混凝土抗分散剂。系统研究了其对混凝土需水性、强度和抗分散性等性能的影响。结果表明 ,JS水下混凝土抗分散剂具有良好的水下抗分散性能 ,各项性能均能满足水下工程施工的需要。论述了JS水下混凝土抗分散剂的作用机理主要表现在桥架作用 ,表面活性作用和桥键作用3个方面。

New JS dispersion resistance agent for under water concrete is developed as per the requirement of concrete construction under water. Its properties influencing on concrete, such as water requirement, strength and dispersion resistance, are systematically studied. The results show that it has good dispersion resistance under water, every property can meet the requirement of under water engineering construction. The paper states its action mechanism mainly expresses in bridge action, surface activated action and bonding action.
