BINDER FOR CONCRETE HAVING ULTRA HIGH STRENGTH AND A METHOD FOR MANUFACTURING CONCRETE USING THE BINDER

摘要

A binder for concrete having an ultra high strength is provided to increases economically an intensity of the concrete by using and charging the proper amount of the filler to an interval of interfaces. A binder for concrete having an ultra high strength comprises cement of 50~90 weight%, a silica fume of 5~20 weight% and a filler of 5~30 weight%. The SiO2 component is 90% or greater in the filler. An average diameter of particles of the filler is 25mum or less.
