Steel slag was used as asource material of geopolymar concrete, with 3 differentcontents 300, 400 and 500 kg/m3. For each slag content threedifferent steel fibers volume were used 0%, 1%and 2% with molarity 10%. Molarity 14% was used with different slag contents and steel fiber volume content 1%. Compressive strength, indirect tensile strength, flexural strength and young's moduluswere measured as hardened concrete properties. Using 500 kg/m3 slag with 2% steel fiber volume with molarity 10% shows 70% young's modulus higher than that without steel fiber content UR - http://172.23.153.220/th.pdf ER -
