Abstract

In recent years, there has been great concern about introducing new supplementary cementitious materials (SCM) in place of Portland cement (PC) in concrete. This study aims to investigate the behavior of sugarcane bagasse ash (SCBA), metakaolin (MK) and millet husk ash (MHA) as SCM with various proportions in concrete. The SCBA, MK and MHA are available in abundant quantities and considered as waste products. On the other hand, cement production emits a lot of toxic gases in the atmosphere which causes environmental pollution and greenhouse gases. Thus, SCBA, MK and MHA might be utilized as cementitious material in concrete for sustainable development. The effect of SCBA, MK and MHA as SCM on the fresh, mechanical properties and embodied carbon of concrete was evaluated experimentally. A total of 228 concrete specimens were prepared with targeted strength of 25MPa at 0.52 water-cement ratio and cured at 28 days. It is found that the compressive strength and split tensile strength were enhanced by 17% and 14.28% respectively at SCBA4MK4MHA4 (88% PC, 4% SCBA, 4% MK and 4% MHA) as ternary cementitious material (TCM) in concrete after 28 days. Moreover, the permeability and density of concrete are being reduced while utilizing of SCBA, MK and MHA separately as SCM and combined as TCM increases in concrete at 28 days respectively. Moreover, the workability of fresh concrete was decreased with the increase of the percentage of SCBA, MK and MHA separately as SCM and together as TCM in concrete. In addition to that, the use of SCBA, MK and MHA individually as SCM and combined as TCM in concrete can reduce the total carbon footprint while reducing the overall cost of concrete manufacturing.
