Abstract
Recently, increasing various constructions, we can choose various cement for each concrete constructions, suited their performance. We studied properties and time interval for placing on consolidated fresh concrete with fresh concrete with ordinary portland cement, moderate-heat portland cement, portland blast-furnace slag cement, portland fly ash-cement, and eco-cement. And we prepared influence of the durability of placing joint. The results suggested, ordinary portland cement had high compressive strength and eco-cement had less bleeding water. Additionally, the results showed the time interval of placing influenced the termination time of bleeding with various cements.
