The cement is famed worldwide, because of its unique properties, but its use significantly increases the carbon emissions. In the present scenario to fulfil the need of sustainable construction, the scarcity of river sand has been replaced with M-sand and there is a need for such alternative construction material. The present study aims to investigate the influence of sugarcane bagasse ash (SCBA) and foundry sand (FS) as a partial replacement for cement and fine aggregate. SCBA is a waste obtained from sugarcane industries which has the properties like corrosion resistance, chloride resistance due to presence of high silica. FS is a by-product from the production of both ferrous and non-ferrous metal casting industries. The study focuses on manufacture of M30 grade paver blocks for non-traffic condition as per IS 15658:2006. The study was carried out using 12 mm crushed stone, SCBA in the proportions of 0, 5, 10 and 15% by weight of cement and FS at constant proportion of 40% by weight of fine aggregate. Experimental tests like compressive strength test, flexural strength test were conducted on the paver blocks to measure the quality. The test results indicate that at 5% SCBA replacement provides optimum values with water absorption of 4.7%, flexural strength of 6.53 MPa and compressive strength of 46.25 MPa. Thereby, use of above alternatives can significantly reduce the problems with disposal of wastes and are economically feasible. These pavers can also be used for medium-traffic category since the strengths were high and found to be almost 40 MPa.
