RILEM TC 247-DTA round robin test: mix design and reproducibility of compressive strength of alkali-activated 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. ; The participation of J. L. Provis and S. A. Bernal (at U. Sheffield), S. Nanukuttan and D. Bondar (at Queen’s University) in this research was sponsored by the Engineering and Physical Sciences Research Council (EPSRC; UK) under Grant Number EP/M003272/1. Participation of V. Ducman was financially supported by the Slovenian Research Agency Programme Group P2-0273. The work and research of K. Dombrowski-Daube in RILEM TC-247 DTA was supported by ZIM - Central Innovation Program, German Federal Ministry of Economic Affairs and Energy (BMWi) by order of the German Bundestag. The contribution of the team at TU Delft led by G. Ye was supported by the Materials innovation institute M2i/Netherlands Organisation for Scientific Research (STW/M2i Project 13361). The contributions of K. Arbi were also supported by Delta Concrete Consult BV. ; Peer reviewed
