Abstract
A concrete block mixture includes Portland cement, a natural aggregate filler, water, and a quantity of particularly sized glass particles. The associated method of producing blocks from the mixture eliminates the need of curing the blocks in a heated humidity controlled environment in order for the blocks to attain the required water content for hydration of the cement.
