In order to study the influence of different fine aggregate systems on the performance of hydraulic concrete,three groups of hydraulic concrete mixtures were configured with river sand,machine-made sand and mixed sand under the medium sand particle gradation in Zone Ⅱ.,and the working performance,mechanical properties and durability properties were compared and studied.The results show that under the same conditions,the working performance,mechanical properties and durability of concrete are significantly different when different fine aggregate systems are used to configure hydraulic concrete mixtures.The comprehensive performance of hydraulic concrete with the configuration of"high-quality machine-made sand+ball milled machine-made sand"is the best,indicating that machine-made sand can completely replace river sand as a fine aggregate in the production of hydraulic concrete,and the performance of using high-quality machine-made sand to prepare concrete is better than that of river sand.
