Abstract

The present work primarily investigates the unconfined compressive strength, the tensile load-diametral strain, the toughness characteristics and the shear strengths of bentonite-lime-phosphogypsum-treated sisal fibre composite. The unconfined compressive strengths and tensile strengths were obtained using the unconfined compressive test and indirect tensile test respectively. The results revealed that the unconfined compressive stress, the deviator stress and the tensile load at failure of bentonite-lime-phosphogypsum composite with untreated sisal fibres could be improved by the successive chemical treatment with sodium periodate, p-aminophenol and sodium hydroxide. The brittleness index and deformability index indicated a change from the brittle to ductile behavior of the bentonite-lime-phosphogypsum-untreated sisal fiber composite, with the chemical treatment.
