lated Blast furnace Slag (GGBS) is processed from Granulated slag If slag is properly processed then it develops hydraulic property and it can effectively be used as a pozzolanic materi al However, if slag is slowly air cooled then it is hydraulically inert and such crystallized slag cannot be used as pozzolanic material Though the use of GGBS in the form of Portland paper is to demonstrate the effects of unprocessed blast furnace slag (RS) on the compressive, splitting tensile and flexural strengths of foam concrete over The Mechanical Properties of Foamed Concrete containing Un
