MANUFACTURING PROCESS OF HIGH STRENGTH CONCRETE USED GYPSUM WASTES(CASO4 2H2O)

摘要

A manufacturing method of high-strength concrete product using gypsum dihydrate is provided to have excellent strength compared with conventional general cement product, to cut down industrial waste and to decrease production cost. A manufacturing method of high-strength concrete product using gypsum dihydrate comprises steps of: agitating refined gypsum dihydrate 50 weight%, portland cement 40 weight% and silica fume 10 weight%; mixing mixed main raw material 98 weight%, cement dispersing agent 0,5 weight% and concrete water reducing agent 1,5 weight% and manufacturing slurry; injecting the slurry into a mold frame and pressing product to 5,000ton~10,000ton; curing concrete product for 28 days; and inspecting quality of high-strength concrete product and shipping excellent product.
