摘要：

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