Behaviour of Concrete with Partial Replacement of Cement by Groundnut Shell Ash
•
1 like•259 views
Use of groundnut shell ash as the partial replacement for cement in concrete production. 7days and 28 days compressive strength and density are calculated. The percentage replacement of OPC contrasts to the control 0% replacement about 15%. The results commonly show a decrease in density and compressive strength as the percentage replacement with GSA increases signifying less hydration with cement. Based on a general analysis of the results as well as the logical assessment to the acceptable standard, a percentage replacement of 10% is proposed for sustainable construction, especially in mass concrete construction.

Abstract: The increases in the production of Portland cement many causes greater concern because of high carbon content. This research focuses on
complete elimination of Portland cement for production of concrete. Geo-polymer concrete utilizes an alternate material including fly ash as binding
material in place of cement. This fly ash reacts with alkaline solution (e.g. NaOH) and Sodium silicate (Na2SiO3) to form a gel which binds the fine
and coarse aggregates. fly ash as a base source material and silica fume as replacements of fly ash by 5%, 10%, 15%, 20%. Concrete cubes of 150 X
150 X 150 mm were prepared and cured under steam curing for 24 hours. Concrete cylinders of size 150 X 150 X 300mm and Concrete beams of size
of 100 X100 X500 mm were also steam cured at 60°C. The silica fume was varied in proportion and results were compared with ordinary Geo-
polymer concrete. And the respective strength gets achieved.
