Abstract

The purpose of this investigation is to determine whether hydrated lime of industrial grade can function as an alkali activator in a one-part system. Alkali-activated concrete has long been proven to benefit from calcium addition in tests. However, the findings of this investigation showed that the strength was not greatly increased when hydrated lime was used as the only activator. This was due to the fact that sodium-based activators improved system pH more than their calcium-based counterparts did. Ettringite and thaumasite crystal forms were also seen in the microstructure. Additionally, the polymerization process was surpassed by the pozzolanic reactions, producing medium strength.
