20.500.12556/DiRROS-16968 RILEM TC 247-DTA round robin test mix design and reproducibility of compressive strength of alkaliactivated concretes The aim of RILEM TC 247-DTA Durability Testing of Alkali-Activated Materials is to identify and validate methodologies for testing the durability of alkali-activated concretes. To underpin the durability testing work of this committee, five alkali-activated concrete mixes were developed based on blast furnace slag, fly ash, and flash-calcined metakaolin. The concretes were designed with different intended performance levels, aiming to assess the capability of test methods to discriminate between concretes on this basis. A total of fifteen laboratories worldwide participated in this round robin test programme, where all concretes were produced with the same mix designs, from single-source aluminosilicate precursors and locally available aggregates. This paper reports the mix designs tested, and the compressive strength results obtained, including critical insight into reasons for the observed variability in strength within and between laboratories. alkali-activated materials (AAM) mechanical properties test method Rilem TC durability alkalijsko aktivirani materiali mehanske lastnosti preskusne metode trajnost true false true E. & F.
