摘要
负温高效防冻剂或负温高效防冻泵送剂是负温高性能混凝土在寒冷气候下强度发展的关键 ,也是防止混凝土受冻害的技术关键 ,其掺量随混凝土设计强度等级的不同而变化。试验表明 ,C50级负温高性能混凝土的抗冻临界强度值在10.0～17.
High performance antifreeze compound or high performance antifreeze compound for pumping concrete is determinant factor of strength development of high performance concrete in cold climate as well as key technology for concrete freezing avoidance.Compound quantity added depends on designed concrete degree.Experiment shows that antifreeze critical strength of C50 high performance concrete is 10.0～17.0 MPa.
