Analysis of the Feasibility of the Use Waste from the Foundry Process in Green Sands in the Manufacturing of Soil-Cement Blocks

Abstract

The production of building blocks with the use of industrial waste has proven to be an important way to mitigate the environmental liabilities that have been obtained by industrialization. In the present study, green cast sand residue was used for the production of pressed soil blocks, replacing part of the soil . Soil-cement blocks with partial replacement of the soil by green sand of function were produced in the percentages of 5, 10, 15 and 20. The mechanical and water absorption tests were performed in blocks and three-block prisms, with satisfactory results showing the possibility of the incorporation of the residue in the block production. Thus, it can be concluded that it is a viable alternative for both the waste -producing industry and the civil construction sector, for employment in small and medium-sized buildings.
