Mix Design and Strength Evaluation of Ambient Cured Permeable Alkali-Activated Concrete
A significant development in the research on the permeable concrete and applications has been noticed in the past decade. On the other hand, a parallel track of research for the sustainable concrete is gaining momentum. It may be an innovative concept of combining the alkali-based binder matrix and a composite with acceptable degree of permeability as a modern construction material for the verities of applications and by limiting the usage of the conventional binders, namely ordinary Portland cement (OPC). However, the development and preparation of a concrete composite demand an accurate mix design for the desirable properties and characteristics. Therefore, the present study has been carried out to obtain the optimum proportions of the alkali-activated permeable concrete (AAPC) constituents with a focus on the preliminary strength properties alongside. The AAPC has been developed by the activation of the industrial waste materials, namely fly ash, silica fumes, and grounded granulated blast furnace slag with the chemical constituents such as sodium silicate and sodium hydroxide in a liquid form. The standard guidelines have been followed in developing AAPC though. The preliminary strength tests have been performed on the specimens. The comparative analysis showed significant improvement in the strength properties of AAPC.
