ABSTRACT
The present study deals with developing a technique to replace the conventional solid concrete slab with hollow terracotta block slab. The objectives include development of an eco-friendly concrete slab with partial replacement of cement with fly ash and natural sand with quarry dust. The first task identified in this study deals with placing of terracotta hollow blocks below the neutral axis of the solid slab concrete portion towards reducing the volume of concrete (about 50 %), since the volume of concrete below the neutral axis isineffective, contributing nothing to the bending strength of the slab. The second task deals with the partial replacement of cement with fly ash, quarry dust and 6 mm chips above the neutral axis of the concrete slab. This paper presents the feasibility of the usage of by product materials like fly ash, quarry dust and 6 mm chips andto study the economic viability of the material and found that the cost has been lowered. From the above methodology it is possible to reduce the CO2 emission in atmosphere towards eco friendly construction technique. The use of fly ash in concrete contributes the reduction of greenhouse emissions with negative impacts on the economy. Tests were conducted on cubes and beams to study the strength of concrete for various combinations of fly ash and quarry dust.
