Analysis of Partial Substitution of Cement with Marble and Granite Powders in Concrete Production

Abstract

The civil construction industry is characterized as the main consumer of natural resources. However, it has great potential in terms of using industrial residues and by-products in the produc-tion of construction materials. Within this context, this study seeks to examine the use of processed marble and granite residues (MGR) generated by the ornamental stone industry as a partial substitute for cement in concrete. To accomplish this, MGR replacements of 5, 7.5, and 10% in relation to cement mass were tested. In terms of the mechanical properties of compressive strength and tensile strength in the produced concrete, the samples with replacement of 5 and 7.5% obtained results that outperformed the reference concrete. On the other hand, the concrete absorption test for the 10% replace-ment yielded greater results than the pilot sample. In general, this study demonstrates the technical viability of partially substituting cement with MGR in concrete production.
