Non-destructive testing and micro-structural analysis of self-compacting concrete using different mineral powder additions in ternary blends (opens in new tab)

This paper investigates the behaviour of ternary blended self-compacting concrete (SCC) in terms of its strength via non-destructive tests and micro-structural analysis. As admixtures, metakaolin (MK) and high calcium fly ash (HCFA) were employed, with waste marble powder (WMP) serving as filler material. A total of 9 SCC mixes, including a control mix, were tested. Different proportions of MK (5% to 20%) were used as partial replacements for cement. A fixed proportion of 15% of HCFA and 20% ...
