The mixture is poured into molds, compacted to eliminate air pockets, and smoothed out on top. After a few hours of setting, the blocks are removed and left to cure for several days—kept moist to ensure they harden properly. This hands-on process is perfect for small construction projects or regions lacking industrial equipment. | History In Pictures | Facebook
