In this study, trying to applying in structure and slab and wall of technical of near-surface transit system, we would make precast concrete for constructing rapidly to diversify subject about lightweight concrete. for this purpose, we experimented lightweight aggregate centrally expected to be applied in this research and would like to suggest fundamental data for manufacturing products as a level of 30, 50MPa precast concrete.
