Perlite is a pozzolan due to its glassy structure and high SiO2 and Al2O3 contents1). It is interesting to use perlite in blended cement, specially for mitigating alkali silica reaction (ASR). The previous studies showed that as a cement replacement expanded perlite powder (EPP) could be used as a cement replacement in small quantities due to its high water absorption capacity. The previous studies showed that when perlite powder incorporated into mortar bars, perlite powder has potential to suppress expansion induced by ASR2). In those programs, the mineral was added to mortar as mass replacement of the OPC. However, further investigation is needed to determine the adequate replacement ratio to suppress ASR in pessimum condition. This paper discusses the effect of EPP to mitigate ASR.
