Concrete blocks are made by hand using a mix of cement, sand, gravel, and water. The mixture is poured into molds, compacted to remove air pockets, and leveled off. After setting for a few hours, the blocks are removed from the molds and left to cure for several days. During curing, they are kept moist to gain strength. This manual method is ideal for small-scale construction and areas without access to machinery. #history #reels #bodybuilder #viral #trending | Inside History
