PURPOSE:To obtain a light-weight concrete structure by a method in which light-weight aggregate is packed into a formwork and high-strength cement mortar is poured into the formwork. CONSTITUTION:A light-weight coarse aggregate 4 of a grain size of 20-50mm is packed into formworks 1 and 2, and high-strength cement mortar 8 is poured into the spaces among the aggregates 4. A light-weight concrete structure can thus be obtained.
