本文采用高性能矿渣复合接合料及HIP－AIOO缓凝高效减水剂，水胶比0．26，配制出坍落度在200mm以上，3小时基本无坍落度损失，满足C80级泵送要求的混凝土，现场实际泵送施工很顺利，其3天强度超过60MPa，28天达97．7MPa。本文还提供了水泥与外加剂适应性的检测方法，研究了高强混凝土可泵性评价指标，确定了以倒坍落度简测定流下时间和扩展度为主，坍落度为参考的可泵性评定方法。 This article uses high-performance slag compound binder and HIP-AIOO retarding superplasticizer, water glue ratio of 0.26, prepared slump above 200mm, basically no slump loss for 3 hours, to meet the C80 pumping requirements Concrete, the site actually pumping construction is very smooth, its strength over 3 days more than 60MPa, 28 days up to 97.7MPa. This paper also provides the testing methods for the adaptability of cement and admixtures, studies the pumpability evaluation index of high-strength concrete, and determines the pumpability based on the determination of down-slump simplification and the downflow time and expansion degree. Evaluation method.
