Abstract: "Cementitious-waste-free-type Completely recyclable concrete(CCRC)," a kind of concrete that permits complete recycling with including some kinds of byproducts from other industries, is defined as "concrete whose binders, additives and aggregates are all made of cement, materials of cement and some byproducts, and all of these materials can be used as raw materials of cement after hardening with no need for ingredient adjustment ." In this paper, the effectiveness of decreasing a large amount of waste by CCRC using byproducts as aggregates, such as blast-furnace slag sand, silica sand, copper slag sand, calcined fly ash aggregate, etc., the typical mixture proportions of CCRC with no need for ingredient adjustment, the mechanical properties and durability of CCRC, and the verification of no need for ingredient adjustment when recycling CCRC as cement materials will be exhibited. When CCRC is used generally, a closed loop material flow of cement itself will be formulated, and it is found to form a circulating system totally different from the material flow of conventional concrete.
