Effect of saw dust, rice husk, and groundnut shell on properties of mubi vimtim clay in Adamawa State Nigeria. Issue 5 (August 2020) - Nathan, C
Abstract: Three agricultural wastes namely saw dust, rice husk, and groundnut shell were used as additives to Mubi Vimtim clay to evaluate its properties. The aim of the research work is to compare the properties of Mubi Vimtim clay when additives are added and when additives are not added. PW430 X-Ray was used to determine the chemical properties of the clay with additives and without additives. The results gave the highest % of oxides of Al2 O3, SiO2, SO3, K2 O, CaO, V2 O5 to be ( 19.67% with sample B, 67.7% with sample A, 0.40% with sample C, 4.98% with sample A, 1.33% with sample A, 0.04 % with sample A and with sample B, 0.05% with sample C and with sample D) respectively. The highest porosity was found to be 17.50% with 30% sample D addition. Bulk density was highest with 2.87g/cm 3 with clay sample A. The highest refractoriness of the clay was found to be 430°C with sample A and lowest with 950°C at 30% sample D addition. The highest thermal shock resistance was found to be 13 cycle at 10–30% sample D addition. The highest breaking load was found to be 380N with sample A. The highest compression strength was found to be 86 Mpa with sample A. The results obtained show the variation of the properties of Mubi Vimtim clay when saw dust, rice husk, and groundnut shell were added.
