高效减水剂是混凝土的常用添加剂之一,对于改善混凝土性能具有显著作用,尤其是对坍落度的影响非常明显,需要在实际的工程中对高效减水剂的运用进行合理把控,确保混凝土质量可靠。本文主要以混凝土坍落度经时损失概述作为出发点,分析了高效减水剂对新拌混凝土坍落度损失的因素,并探讨了控制措施,以期为提高混凝土工程施工中质量保证提供一些参考和意见。 Superplasticizer is one of the common additives for concrete, which has a significant effect on improving the performance of concrete, especially on slump. It is necessary to properly control the application of superplasticizer in practical engineering Concrete quality and reliable. Based on the summary of the slump loss of concrete during the passage of time, this paper analyzes the factors that affect the slump loss of fresh concrete by the superplasticizer, and discusses the control measures in order to provide some references for improving the quality assurance in concrete construction opinion.
