Description 862-865
A current challenge for the concrete industry is to add admixtures to produce concrete with improved strength. With this
view, the present study explores compressive strength (fck) and flexural strength (fcr) for M40 grade of concrete with partial
replacement Portland Pozzolana Cement (PPC) with metakaolin (Mk) in the range of 4% to 24 % by the weight of cement
by adding ViscoFlux-2230+ as a superplasticizer to make the concrete workable. It was observed that up to 16% addition of
metakaolin increased compressive and flexural strength by 27% and 15.78% respectively compared to ordinary concrete at
28 days. Similarly, for 7 days compressive and flexural strength was increased nearly by 20% and 13% respectively and for
90 days, it was observed to be nearly 15% and 16% respectively. A relationship between the compressive strength (fck) and
flexural strength (fcr) of Mk concrete is developed. The early age compressive strength development was greater practically
in all Mk concrete. Indirectly increasing the rate of metakaolin can lower the regularized CO2 emission and resource
consumption. From the results, concrete may be recognized as sustainable concrete.
