Feasibility Study of the Incorporation of Micronized Ceramic Waste in Structural Concrete

Abstract

Reducing waste disposal from the rock industry and reducing sand consumption in the civil
construction sector is important for sustainable development. One strategy to minimize these
problems is to use waste as partial substitutes in the production of structural concrete. Thus, this
study aims to analyze the physical and mechanical properties of structural concrete modified by the
addition of micronized ceramic waste of marble and quartzite and evaluate the feasibility of using
these materials in civil construction. The dosage and molding of the specimens in the dimensions of
10 cm x 20 cm was carried out, with partial replacement in the 20 % content for both residues,
individually. Physical and chemical characterizations were carried out for the materials used, and
then the physical and mechanical performance of the concretes was evaluated through tests of
absorption, simple compression strength, and tensile strength by diametrical compression. The
incorporation of these residues provided an increase in absorption and again in tensile strength.                                          Concrete modified with marble residue showed loss of compressive strength and concrete modified
with quartzite residue gained compressive strength. Therefore, the use of micronized marble and
quartzite waste, as a partial substitute for the conventional fine aggregate, is a viable alternative for
inserting material in a new production cycle.
