Rice Husk Ash Pozzolanicity Assessment by Resistivity Method

Assessment of pozzolanic reactivity is commonly based on a direct and indirect method which mostly used the electrical conductivity method. However,these methodsare limited by long-duration requirements or need to be done in laboratory. By modifying sandbox test measure resistivity Rice Husk Ash (RHA) as pozzolan, this investigation tries offer simpler that can situ. The RHA was heated oven with several temperatures varying from 100C 600C tested for its mixing it laboratory-gradelime. value then compared Luxan using same materials. results showed similar trend Hence new classification proposed linewith assessment.
