Optimization of Calcined Termite-Mound Material (CTM) Mortar and Concrete using Response Surfaces Methodology

This study is aimed at the optimization of calcined termite mound material incorporated in mortar and concrete using Response Surfaces Methodology (RSM). The substituting cement varied from 5 to 15% interval 5% concrete. Sikament NN was added 1.0 3.0 1.0. Test conducted on were: consistency setting times. For concrete, specimens were cast tested failure for all mixes curing periods 3, 7, 28, 60 90 days. Modelling carried out Design-Expert software version 11.0 with CTM (5%, 10% 15%) (1.0%, 2.0% 3.0%) levels taking as input variables. output responses consistency, times, compressive strength test after 90days curing. Comparison made performance blended controls terms times strengths. Results analysis variance (ANOVA) indicate that both are influential variable developed models RSM statistically significant factor levels. optimum mix obtained by addition 2.09 % replacement 0.871 desirability. In 2.05 desirability optimum.
