    Searching for alternative materials to Portland cement mixtures has become a strong stream tailoring engineering research and practices today. In this respect, alkali-activated binders (AABs) with glass powder and slag (GP/S) were considered in this work. Indeed, our goal was to provide a comprehensive investigation of GP/S mixtures with varying glass powder content. Thus, five pastes’ PPC, PS, PG20, PG40, PG60, and five mortars MPC, MS, MG20, MG40, and MG60 were made. Mortars were tested for mechanical strengths, water sorptivity, and 10 % magnesium sulfate attack. Pastes were investigated by FTIR. The results showed higher mechanical strength of activated formulae, with 20% GP as optimum; elevated AABs sorptivity, CSH, and (C,N)ASH were the main hydration products, cracking/dissolution is the main mechanism of AABs under magnesium sulfate.
