Tang Kaijing and others studied basalt mechanism sand, river sand, and quartz mechanism sand, and found that different rock types of mechanism sand have a significant impact on the workability of C50 concrete.
Differences in morphology and gradation are the reasons for the decrease in workability.
Donza et al.
conducted a comparative study on the workability of limestone, granite, dolomite mechanism sand, and natural sand concrete, and found that the chemical mineral composition, rock type, bulk density, and internal structure of the mechanism sand parent rock are the main factors affecting the performance of mechanism sand.
