Ordinary Portland cement manufacturing can be affected to over 5 per cent of global CO 2 emissions a demand for cement continues to rise. The architecture sector led planners and architects to look for alternate cemented materials for potential use in concrete buildings. Such natural admixtures like metakaolin and kenaf fibres can be used to alter pozzolanic behaviour and mechanical properties in concrete. The chemicals used by the SCM in construction to replace cement such as metakaolin not only minimize carbon dioxide emissions, but also greatly increase workability and longevity. The metakaolin is replaced with cement in 5%,10%,15% and 20% by its weight. The Kenaf fibre is added in concrete about 0.5% and 1% by the volume fraction of cement.
