Physical and Mechanical Characterization of Artificial Stone with Marble Calcite Waste and Epoxy Resin

Abstract

The incorporation of calcite marble waste in epoxy resin for the production of artificial stone can represent a technical-economical method and environmentally viable, reducing the amount of discarded residue in the environment, and adding economic value to marble waste and enabling the generation of jobs. The production of natural stone in Brazil recorded an exorbitant amount of waste generated in marble processing. Only 75% of marble taken from the deposits it becomes the finished product the rest is discarded. This study aimed to evaluate the mechanical and physical properties of produced artificial marble based in calcite marble waste and epoxy resin. The vacuum vibro compression was used for production as artificial marble and the specimens were cut according to standart NBR 15845. The results indicated that the artificial stones exhibit physical and mechanical results within the expected range for these kinds of materials. Artificial marble with a maximum flexural strength of 31,8 MPa, maximum compressive strength of 85,2 MPa, water absorption below 0.05% and a satisfactory adhesion between load and resin were obtained for the materials produced with 80% wt marble particles and 20% wt epoxy resin, enabling the development of an alternative material for civil construction applications.

Transforming Marble Waste into High-Performance, Water-Resistant, and Thermally Insulative Hybrid Polymer Composites for Environmental Sustainability

“…Researchers have attempted to use marble waste particulates in paver blocks [ 19 ], soil stabilization [ 11 , 20 ], cement-based adhesive mortar [ 21 ], and as a replacement of conventional natural aggregates in concrete [ 4 , 8 , 22 , 23 , 24 , 25 ]. Attempts have also been made to use marble waste for manufacturing cementitious roofing tiles [ 26 ], preparing polymer concrete with unsaturated pre-accelerated polyester resin [ 27 ], a cement-based composite material with expanded perlite and tragacanth (plant resin) [ 28 ], composite bricks [ 2 , 6 , 29 ], artificial stones, unsaturated polyester resin, and epoxy resin as binders [ 30 , 31 ].…”

Sustainable approach towards utilizing Makrana marble waste for making water resistant green composite materials

“…Some pores were also observed which can be attributed to the air bubbles trapped in matrix during the high viscous mixing of resin. Air voids/pores results in inefficient adhesion and also act as stress concentration points and thus are the reason for lesser strength of composite materials [33].…”

Compósitos Poliméricos Incorporados Com Resíduo Da Marmoaria: Resistência Às Chamas/Polymeric Composites Incorporated With Marble Residue: Flame Resistance

“…propriedades de PA e AA possuem sensibilidade com a adição de carga dentro da matriz, no qual, muita das vezes, estabelecem uma relação de complemento, devido a influência de uma propriedade sobre a outra de acordo com a adição de teor de carga. Silva et al (2018), em seus resultados, comentam sobre a qualidade alta de impermeabilidade do resíduo de mármore e granito, devido a baixa absorção de água e porosidade.…”
