“…As a very widely used material in the construction industry, concrete consists mainly of cement, water, and aggregates; the latter makes up about 55%–80% of the concrete volume 1 . As researchers have always tried to enhance the concrete quality and enable its properties to comply with code regulations and principles, 2,3 the self‐compacting concrete (SCC) was invented in mid‐1980s to improve the vibration conditions, reduce the labor force, increase the quality, and optimize the flowability 4,5 . It has more powder material and less coarse aggregate (CA) volume than normal vibrated concrete (NVC) to ensure fallibility, passability, and inseparability 6 .…”
