METHOD FOR PRODUCING HIGH STRENGTH CEMENT-BASED HARDENED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a high strength cement-based hardened body using granular silica fume, in which kneading time can be reduced.SOLUTION: Provided is a method for producing a high strength cement-based hardened body of producing a high strength cement-based hardened body by kneading a cement composition including powdery silica fume obtained by pulverizing granular silica fume. Preferably, the kneading time of the cement composition including the powdery silica fume obtained by pulverizing is 70% or lower of the cement composition including the granular silica fume before the pulverization.
