In this study, a polymer composite is made using chemically treated jute fiber and waste floor tile powder as an alternative source for roof tile application. The wear qualities were examined at various ages, and the outcomes were optimized. In order to improve the wetting properties of the jute fiber, it was chemically treated. MINITAB software was used to develop Taguchi method parameters such as jute fiber percentage, waste tile powder percentage, and NaOH chemical treatment using the MINITAB software. It was determined that hardness was the most important characteristic in terms of wear properties after the specimens were subjected to ageing and abrasion wear testing and hardness tests were carried out as per normal protocols. As a result of the waste tile powder addition, the surface and core pore formation rates were reduced and the wear index rates were low. Jute fiber with 15%, 9% tile powder, and 5% NaOH treatment were found to have the lowest wear index of the other specimen compositions tested, according to the wear index. Specimen made with 5% jute fiber addition, 9% tile powder inclusion, and 10% NaOH treatment, on the other hand, had more hardness. Degradation of the fibers and delamination are side effects of the ageing process. The wear resistance of the surface was increased by the use of waste tile powder.

“…Research by Revuelta (2021) revealed that life span of ceramic roo ng tiles average 75 years, which highlight their durability and are easily recycled at the end of their service life. To continue in manufacturing ceramic products, and with the fact that clays as raw materials may become scarce in future (Gonzalez et al 1990;Kazmi et al 2016;Subashi De Silva and Malwatta 2018;Terrones-Saeta et al 2020) and considering that major countries like China, are already limiting their productions due to insu cient raw materials (Lingling et al 2005;Chen et al 2011;Terrones-Saeta et al 2020), there is an urgent need to source for cheap, locally available and sustainable materials that can meet the requirements of the raw materials as alternative to the depleting natural resources. With the innovation of waste to wealth technology, it has become imperative to evaluate any alternative material (may be wastes or unusable materials) with less energy usage and excellent properties to ensure better red products.…”

Quarry wastes from indurated shales with huge reserves across Abakaliki, Southeastern Nigeria were evaluated for use as raw materials in manufacturing of roofing tile. Firstly, the indurated shales were investigated by their mineralogical (X-ray diffraction, XRD), chemical (X-ray fluorescence) and physical (grain size distribution and Atterberg limits) characteristics. As technologies of building-related ceramic production involved firing to varying temperatures, ISQW samples were fired to determine their technological properties (linear shrinkage, weight loss, water absorption, bulk density and flexural strength). From the results, ISQWs composed predominately of fine particles (clayey-silt) with medium plasticity. The XRD revealed predominance of illite-chlorite-vermiculite with high contents of quartz and variable percentage of carbonate and feldspar. The oxides were dominated by SiO2 and Al2O3, low contents of ferromagnesian elements with considerable amounts of alkali (K2O and Na2O) which can act as fluxes and may have effect during sintering. The CaO concentrations are variable and relate to carbonate contents. Characterizations based on compositional ternary, clay workability chart and Winkler diagrams revealed their acceptable level for ceramic applications. The Winkler and McNally diagrams revealed heterogeneous behaviors as the samples fell within vertical corrugated bricks, perforated products and tiles production. The ISQWs fired at 1000oC revealed considerable weight loss, linear shrinkage and water absorption with unsatisfactory performance for flexural strength. Flexural strength increased as firing temperature increased due to the formation of dense phase. Beneficiation of ISQWs in order to achieve excellent properties and reduce sintering temperature for their usability in production of roofing tiles is recommended.

“…This fact is mainly due to the high production of materials as well as their low cost. More specifically, the consumption of ceramic materials in the building sector, among others, causes the scarcity of natural resources such as clay [ 3 , 4 , 5 ] as well as generates significant CO 2 emissions due to poorly optimized industrial processes [ 6 ]. Moreover, the construction sector accounts for the largest percentage of the global energy consumption [ 7 ].…”

Development of Geopolymers as Substitutes for Traditional Ceramics for Bricks with Chamotte and Biomass Bottom Ash

et al. 2021

The greater environmental awareness, new environmental regulations and the optimization of resources make possible the development of sustainable materials as substitutes for the traditional materials used in construction. In this work, geopolymers were developed as substitutes to traditional ceramics for brick manufacture, using as raw materials: chamotte, as a source of aluminosilicate, and biomass bottom ashes from the combustion of almond shell and alpeorujo (by-product produced in the extraction of olive oil composed of solid parts of the olive and vegetable fats), as the alkaline activator. For the feasibility study, samples were made of all possible combinations of both residues from 100% chamotte to 100% biomass bottom ash. The tests carried out on these sample families were the usual physical tests for ceramic materials, notably the compression strength test, as well as colorimetric tests. The freezing test was also carried out to study the in-service behavior of the different sample groups. The families with acceptable results were subjected to Fourier transform infrared (FTIR) analysis. The results of the previous tests showed that the geopolymer was indeed created for the final families and that acceptable mechanical and aging properties were obtained according to European standards. Therefore, the possibility of creating geopolymers with chamotte and biomass bottom ashes as substitutes for conventional ceramics was confirmed, developing an economical, sustainable material, without major changes in equipment and of similar quality to those traditionally used for bricks.
