Strength, electrical resistivity and sulfate attack resistance of blended mortars produced with agriculture waste ashes
Source abstract
Abstract
The performance of blended mortar mixtures produced with partial replacement of cement with agriculture waste ashes of rice husk, sugarcane bagasse, corncob, and waste wood were evaluated in this investigation. Cement was replaced at 5, 10, and 15 wt% with each of agriculture waste ashes for manufacturing of blended mortars. Fresh mixture properties, compressive strength, electrical resistivity, and sulfate resistance of the mixtures were evaluated at 7, 28, 56, and 90 days of curing ages and compared with that of control mixture. Test results showed a significant improvement in the later age compressive strength, electrical resistivity and sulfate resistance of blended mortar mixtures. Considerable increase in the initial and final setting times of the blended mortar mixtures was noted. Increasing demand for the superplasticizer dosage to achieve the target flow level was recorded with increase in percent replacement of cement with the agriculture waste ashes. Blended mortar mixtures produced with rice husk ash as partial replacement of cement showed superior performance among the four types of mixtures. A replacement level of 10 wt% of cement with the agriculture waste ashes was observed to be the optimum to achieve enhanced strength and durability of the blended mortar mixtures.
