Evaluation of the potential use of granite waste in products of the red ceramic industry in the state of Amazonas

Abstract

The increase in the exploitation of raw materials in the civil construction sector has led to an increase in damage to the environment, mainly due to the improper disposal of granitic waste. However, this fact has caused damage to the environment. Therefore, this research aims to analyze the influence of the introduction of granite waste in a clay matrix aiming its use in the red ceramic industry. For this, the clay from the ceramic pole in the city of Iranduba -AM and granite waste from a company located in the municipality of Presidente Figueiredo -AM were collected. Formulations were made containing three levels of waste (0, 10 and 20% mass) and three firing temperatures (1173, 1273 and 1373K). The materials were characterized by X-ray fluorescence spectroscopy, X-ray diffraction, scanning electron microscopy and the following technological properties were determined: water absorption; linear retraction; apparent porosity; specific mass; and 3-point flexural rupture module. The results showed that the glassy phases generated provide a better densification of the formulations with 20% of waste, sintered at 1373K, as they presented favorable mechanical properties for the manufacture of red ceramic products, providing a correct destination of the waste and providing alternatives for the social, economic context and environmental impact of the Amazon region.

Experimental study of the production of resin granite and marble using their solid waste

“…Given the importance of finding a better destination for granite and marble waste, other research can also be found, such as applications in red ceramics [11], in materials and concrete structure [12,13], in lightweight aggregates for concrete [14], among others.…”

Eco-Efficient Artificial Stones Produced Using Quartzite Quarry Waste and Vegetable Resin

“…The waste generated in the production of ornamental stones has a great capacity to be used as a by-product for the development of new materials, and thus several studies have been carried out with the aim of attesting to the technical feasibility of using this waste. There are studies that use the fine waste from processing to produce ceramics [5][6][7], cement, mortar and plaster [8], glass [9], coarse waste as an aggregate for civil construction [10], and artificial stones, among others.…”
