Strength Properties of Concrete with Rice Husk Ash and Quarry Dust for Sustainable Construction Applications
The economic and environmental difficulties related with the utilization of traditional construction material for construction projects, such as use of cement and river sand have risen in parallel with the human population growth. As a result, researchers are focussing alternate construction materials that are cost effective and sustainable. The aim of current investigation is to develop a cost effective and sustainable concrete composite using rice husk ash and quarry dust. The conventional concrete with a characteristic strength of 30 MPa, was developed with cement and river sand. Initially, rice husk ash was proposed as a substitute for cement in varying percentages of 10 to 30%. Quarry dust was then utilized as a substitute for sand in mixes comprising rice husk ash with percentages ranging from 10 to 30% to develop non-conventional concrete. The slump of concrete and the strength characteristics such as compressive, split tensile and flexural strength were measured at 7 and 28 days, respectively. The strength characteristics of the specimens decreased with increasing percentage replacements of quarry dust in comparison with conventional concrete. Based on the experimental findings, the concrete having 10% rice husk ash and 20% quarry dust having superior strength properties. Hence rice husk ash and quarry dust could be employed as partial substitutes for cement and river sand, respectively, in the development of sustainable construction materials.
