Abstract
CO2 emission has increased annual average of 2.5% during the past decade by fossil fuels combustion and cement production, even though the international community efforts to reduce CO2 emission. The alternative material of cement has been attracting attention in construction projects. Especially, the alkali activated slag(hereafter, AAS) concrete is able to use for a structural vertical member because of compressive strength, over 40MPa. However, the research about time-dependent deformation such as creep which is important to strength member is inadequate. Therefore, is this study, experiments were performed with respect to time-dependent deformation including the drying shrinkage and creep deformation of AAS concrete. The AAS concrete that is set equal to ordinary portland cement(hereafter, OPC) concrete was measured time-dependent deformation. The creep deformed ratio of AAS concrete was more than OPC concrete by approximately 4.3% and the dry shrinkage deformation of AAS concrete was
