Compared to ordinary Portland cement (OPC) concrete, alkali activated compounds refer to inorganic materials that cement is not the main constituent in their mixes. In fact, alkali activated concretes have two main parts in their binder structure: source material and alkaline activator liquid. In this study, the binder consists of blast furnace slag as a source material and sodium silicate solution (wt. ratio: SiO2/Na2O = 2.33) and 6 M potassium hydroxide which are incorporated as alkaline activator liquids. Since there are several parameters that affect the properties of these concretes, 9 alkali activated concrete mix designs are utilized to investigate the influence of source material amount, solid part of alkaline activator, solid part of sodium silicate solution and the ratio of water to binder. Furthermore, one mix design for OPC concrete is performed to compare with alkali activated slag (AAS) concrete characteristics. |
