Study on the Strength and Microcosmic Characteristics of C50 High-Performance Concrete (HPC) Containing Manufactured Sands
In this paper, C50 high-performance concrete (HPC) containing manufactured sand was prepared.First, three different gradations of aggregates and three different types of admixtures with significant differences in specific surface area, porosity, and water ratios were used to prepare nine groups of concrete mixtures.Second, the effect of the aggrega
