Abstract Many standardised durability testing methods have been developed for Portland cement-based concretes, but require validation to determine whether they are also applicable alkali-activated materials. To address this question, RILEM TC 247-DTA ‘Durability Testing of Alkali-Activated Materials’ carried out round robin carbonation and chloride penetration test methods, applied five different concretes based on fly ash, blast furnace slag or metakaolin. The appeared overall demonstrate...
Abstract The aim of RILEM TC 247-DTA ‘Durability Testing Alkali-Activated Materials’ is to identify and validate methodologies for testing the durability alkali-activated concretes. To underpin work this committee, five concrete mixes were developed based on blast furnace slag, fly ash, flash-calcined metakaolin. concretes designed with different intended performance levels, aiming assess capability test methods discriminate between basis. A total fifteen laboratories worldwide participated...
Abstract The RILEM technical committee TC 247-DTA ‘Durability Testing of Alkali-Activated Materials’ conducted a round robin testing programme to determine the validity various durability methods, originally developed for Portland cement based-concretes, assessment alkali-activated concretes. outcomes tests evaluating sulfate resistance, alkali-silica reaction (ASR) and freeze–thaw resistance are presented in this contribution. Five different concretes, based on ground granulated blast...
