METHOD FOR CONTROLLING ULTRA-HIGH STRENGTH CONCRETE FOR MAXIMIZED STRENGTH
专利汇可以提供METHOD FOR CONTROLLING ULTRA-HIGH STRENGTH CONCRETE FOR MAXIMIZED STRENGTH专利检索，专利查询，专利分析的服务。并且The present invention relates to a method capable of maximizing the strength of an ultra-high strength concrete hardened body through the same mixing design using the same mixing materials. The method for controlling ultra-high strength concrete for maximized strength according the present invention is characterized by: designing mixing to have a slump flow at a level of 850±50mm in the mixing of ultra-high strength concrete; designing mixing to have an air content of 1.0-2.0% in the mixing of ultra-high strength concrete; first introducing coarse aggregate and silica fumes in the mixing of ultra-high strength concrete, introducing another mixing ingredient after dry mixing for 20 to 40 seconds, and then mixing; introducing water at the very end of the mixing of ultra-high strength concrete, stopping of mixing for 200 to 400 seconds and undergoing a process in which the concrete is left standing after 150 to 200 seconds of mixing, and then mixing the concrete again for 150 to 200 seconds; and pouring ultra-high strength concrete for self-leveling; or performing wet curing for 14 to 28 days after the pouring of ultra-high strength concrete and then air-dry curing. The present invention as characterized above can be effectively applied to cases in which ultra-high strength concrete of 200 MPa or greater is designed for mixing.，下面是METHOD FOR CONTROLLING ULTRA-HIGH STRENGTH CONCRETE FOR MAXIMIZED STRENGTH专利的具体信息内容。
