文摘

Slag reactivity in cementitious materials depends on achieving powder finesse. One hour of high energy milling is sufficient to use slag as substitute to cement. Conventional milling has negative impact on mechanical performance of cement paste. High energy milled slag improves mechanical performance of cement paste.
