Highlights Calcium oxychloride is mitigated using alternative SCMs in cementitious paste. Rice husk ash is an effective material to mitigate calcium oxychloride. Inert mineral fillers are not effective to mitigate calcium oxychloride. TGA, LT-DSC, and modified R 3 test aid in predicting calcium oxychloride mitigation.
Abstract Supplementary cementitious materials (SCMs) are known to reduce calcium oxychloride (CAOXY) contents in cementitious pastes. However, when availability or cost precludes the use of traditional SCMs, such as fly ash, mitigation could be provided through alternative materials. Fly ash (FA), rice husk ash (RHA), bottom ash (BA), limestone filler (LS), nepheline syenite filler (NS), sandstone filler (SS), and silica flour (SFL) were evaluated for CAOXY mitigation in cementitious paste using low-temperature differential scanning calorimetry, reactivity testing, thermogravimetric analysis, and compressive strength testing. The order of CAOXY mitigation from least to most effective is SS, LS, SFL, NS, BA, FA, and RHA.
