Since
1882, when the first concrete block was molded from a mixture of cement,
gravel, sand, and water- concrete masonry has become the standard
building material. Today, other ingredients such as air-entraining
agents, coloring pigment, and water repellent are added to concrete
block mixture to further increase the versatile uses of concrete block.
In addition, concrete itself permits strength, durability, architectural
freedom and versatility.
