Feasibility of Manufacturing Paver Blocks Using Waste Materials

Abstract

The issue of increasing demand for building materials has provided a need for sustainable materials to be manufactured with proper waste usage. In this paper, an experimental investigation was carried out on a paver block to study characteristics of Ground granulated blast furnace (G.G.B.S.), Iron fillings & glass fibers. Ground granulated blast furnace (GGBS), Iron fillings, fly ash & glass fibers were used and the effect of their addition on paver block, behavior was studied. Results has given the addition of G.G.B.S., iron & glass fibers increased the compressive strength, flexural strength & water absorption as compared to conventional paper block. For the development of the paver block, G.G.B.S., Iron fillings, Glassfibre is used as a partial replacement of cement & fine aggregate (FA) & coarse aggregate (CA) respectively. The develop product was tested according to the Indian Standards (IS) & the effect of addition of GGBS, iron & glass fiber was tested. The combination of Iron fillings (4%) + Cement (21%) + F.A. (25%) + C.A. (50%) has given the compressive strength of 62.10 MPa & flexural strength 6.2 MPa. Water absorption is 4% which is also within the limit. Hence, the study concluded that the use of above waste materials, as an alternative raw materials for the production of paver block was feasible.
