The strength and microstructure of alkili-activated slag cement concrete (ASC-concrete) have been examined. A series of factors (activator concentration, curing times, ratio of activator/slag) were used to observed the development of strength in ASC-concrete. XRD, SEM and porosity analysis were used to observed the reaction products and microstructure of the ASC-concrete. At 28 days of reaction, the ASC-concrete prepared from activator/slag ratio of 0.5 activated with 3 M and 5 M NaOH and cured at room temperature, develop compressive mechanical strength of 20.4 MPa and 22.5 MPa, each other. The main reaction products in ASC-concrete were low-ordered calcium silicate hydrate produced from alkali-activated blast furnace slag. The higher strength in ASC-concrete was attributed to a more compact and continuous gelatinous matrix due to restructuring of reaction product.
