Concrete made with normal-weight fine and coarse aggregates generally weights about 144 lb / ft3. Boulders and cobbles are generally not used in their as-mined size but are crushed to make various sizes of coarse aggregate and manufactured sand and mineral filler. Gravels and naturally occurring sand are produced by the action of water and ...

According to ASTM C 330 [8], concrete constructed from structural-grade light-weight aggregates must have a split tensile strength of at least 2 MPa. Kokal [46] said that the tensile failure of the split samples did not exhibit interfacial bond failure. The SEM microstructural studies verified this.
