No – fines concrete: It is a type of light weight concrete produced by omitting the fine aggregates from conventional concrete. This concrete has only cement, coarse aggregate and water. Due to absence of fine aggregates, concrete will have large voids, resulting in light weight. Even though there is reduction in strength, there is no capillary movement of water, resulting in low C20 concrete mix and Gen 3 concrete is commonly used for lightweight domestic applications and foundations, such as driveways and garage, shed & workshop bases. It can also be used to construct internal floor slabs so long as they contain no embedded metal.
