Recommendation of RILEM TC 258-AAA: RILEM AAR-10: determination of binder combinations for non-reactive mix design using concrete prisms–38 °C test method

This RILEM AAR-10 concrete prism test (CPT) is a performance method for testing aggregate combinations together with various binder (i.e. composite cements or pure Portland + Supplementary Cementitious Materials; SCMs). The covers the measurement of expansion produced by alkali-aggregate reaction prisms stored at 38 °C in humid environment which accelerates alkali-silica (ASR). principle this founded on AAR-3 method. However, dimension increased to reduce alkali leaching during exposure prisms. has two different applications, i.e., (1) assessment how SCM content may ASR susceptibility an combination: enabling use specific reactive product critical combination(s) (minimum requirements) producing non-reactive concrete. (2) available can be reduced SCMs: determination required general composition regional worst-case combination (within that region). also used threshold mix CEM I / Ordinary cement.
