Type: preprint
Abstract: This research work focuses on the experimental investigation of the thermal properties, strength, durability and microstructure analysis of optimized green concrete developed using pond ash and ground granulated blast-furnace slag (GGBS). The objective of the study is to understand the effect of partial replacement of fine aggregate and cement (OPC) using pond ash and GGBS respectively. An optimum mix ratio for the replacement of pond ash and GGBS was determined from the material characterization of 16 trail mixes. Then, the optimized concrete mix was tested for mechanical properties, durability and thermal characterization. Moreover, the microstructure analysis of the optimized mix was performed using Scanning Electron Microscope (SEM) to overview the chemical constituents, bonding of molecules at interfacial transition zone (ITZ), the effect of elevated temperature, etc. In addition, a detailed multilinear regression analysis was performed and a new equation was proposed to determine the compressive strength of concrete with GGBS and pond ash. The predictions obtained from the proposed analytical equation showed a good match with the test results.
