Bond strength and abrasion resistance of alkali activated concretes (AAC) were examined experimentally by CCD method. AASC were designed and produced considering the SC, SM, CT and ECT as the CCD’s independent parameters. Compressive strength, split tensile strength, ultrasonic pulse velocity (UPV), abrasion and bond behavior of AAC were defined. Effects of each independent parameter on the dependent parameters were statistically analyzed. The optimum values of the parameters studied were defined as CT of 66 °C, ECT of 14.76 h, SC of 5.72% and SM of 1.0 for the defined multi-objective optimization problem.
