砂对聚羧酸掺量、砼用水量、强度的影响

摘要

This paper through the test systematical y under-stand the ef ects of the sand mud content, fineness modulus of raw materials on performance of concrete mixture, water cont-ent, strength and polycarboxylic acid dosage, provides the bas-is to guide the actual production and timely adjust the mix.%本文通过试验系统了解原材料砂含泥量、细度模数对混凝土拌合物性能、用水量、强度及聚羧酸掺量的影响，为指导实际生产及时调整配合比提供依据。
