Concrete without cement is possible with the use of fly ash as an alternate for cement. It matches both the chemical and physical properties of cement. Thus it has the ability to replace cement completely. The word "concrete" defines as the bonding between aggregates, cement and water. Concrete is the most common material used for construction [hellip;]
