Recently a full factorial design is an experiment allows the investigator to study the effect of each factor on the response variable, as well as the effects of interactions between factors on the response variable. The objective of this study is to identify the significant factors and interactions involved in maximizing compressive strength of geopolymer mortar when brick waste activated is used as cement. In this respect, experimental factors at two levels, which are alkaline activator type (Na2SiO3+ NaOH), curing temperature (40°C - 60°C) and cure duration (7-28 days), are selected as possible applicants affecting the compressive strength.According to the full factorial analysis, at the 60 °C curing temperature level when brick waste activated is added to mortar, the compressive strength will be good enough after 28 days. The physic - mechanical analysis shows an excellent agreement between the measured and the estimated values for both the compressive strength and only slight deviations were noticed for high curing temperature. The use of appropriate values of matrix strength and consideration of the improvement in mechanical behavior allow a good agreement between the experimental values and the estimated values .The results demonstrate that brick waste after activation can be used in construction industry.
