Abstract

Concrete is the most extensively used composite construction material in the world, which is made primarily from cement, water, fine aggregate and coarse aggregate. The present investigation is to find suitable alternative materials for fine aggregates and cement due to their scarcity and depletion of natural resources. Robo sand and sugarcane bagasse ash are such alternatives which are by-products from industries and these are ecofriendly. With the usage of these alternative products an attempt has been made to replace cement with 12% sugarcane bagasse ash and fine aggregate with artificial robo sand in required proportions (0%, 50%, 100%). Strength parameters such as compressive strength, split tensile strength, flexural Strength, In-plane shear strength by mode II fracture tests are conducted at the age of 28 days. The durability tests are also conducted by immersing specimens for 28 days in 5% concentrated Hydro
Chloric Acid, Sulfuric Acid and Sodium Sulphate solutions. The results are analysed and reported.
