摘　　要：分析砂石吸水性、含泥量对混凝土坍落度经时损失的影响,采用预湿骨料技术控制混凝土拌合物的质量,减少了混凝土坍落度经时损失,降低了混凝土退灰率,节约了生产成本,保证了混凝土强度及结构实体的强度。Influence of the water absorption of sandstone and silt content on the concrete slump loss was analyzed,and the prewetting aggregate technology was used to control the quality of the concrete mixture,which reduced the slump loss,lowered the return rate,saved the production cost,and ensured the strength of concrete and the structure of entity.

关 键 词：预湿骨料 坍落度 经济效益
