Kaolin beneficiation mining is one of the sectors in a supply chain of ceramic industries, supplying qualified raw materials for manufacturing high-quality ceramic products. However, substantially by-products are generated from the mining process. The abundance fraction of sand-wastes is generated by approximately 40% of kaolin material input, amounting to 172,200 tons/ year. The burden of the manufacturer is attempting to find out the way to solve this problem. The effort of this research is to utilize waste by-products (sand-wastes) from kaolin mining. The eco-friendly Non fired wall tiles are developed with the combination of sand-wastes, laterite soil, river sand, and Portland cement Type I. They have been compared with the Thai Industrial Standard (TIS 2508-2555). Results of the experiment show that the proposed wall tile can achieve the physical properties of TIS 2508-2555. Scanning Electron Microscope (SEM) has been studied to analyze the surface morphology of specimens. This can be summarized that 25% of sand-wastes can be utilized in wall tiles. In addition, energy-saving for non-firing products is achieved. Furthermore, energy-saving is also calculated and compared with fired wall tile which has similar properties.

Sediment soil is the wastes from water supply treatment process. It leads the high burden of disposal cost to the metropolitan waterworks authority. Utilizing of sediment soil has been studied. Likewise, this research aims to utilize the sediment soil, wastes of water supply treatment process for producing non-fired wall tiles. In the experiment, four types of raw materials have been employed consisting of sediment soil, laterite soil, Portland cement type 1 and fluvial sand. Constructed formulas have been divided into two groups. Substitution of sediment soil for laterite soil is the first group, and substitution for fluvial sand is the second group. After mixing the raw materials of all formulas, forming specimens by uni-axial pressing at 100 bars with dimension 100x50x8 mm. have been carried out. Then, they have been sprayed and aged for 7, 28, and 60 days at room temperature. After that, testing the specimens’ properties has been performed based on TIS 2508-2555 standard. The formula contains 10% of sediment soil wastes offering the highest bending strength 7.51 Mpa, and 6.87% water absorption at 60-day aging. The experimental results show that adding the sediment soil to the basic composition has an effect on the bending strength and water absorption. The water absorption property can pass standard TIS 2508-2555, and bending strength nearly passes the standard. Energy saving cost has been compared with fired wall tiles at 850°C. It can save cost by $13 USD/cycle/day In addition, imaging analysis using Scanning Electron Microscopy has been employed for analysing the microstructure of specimens at different curing age for 7, 28, and 60 days.

This research is aim at developing marble-looking fired clay tile by utilizing waste glass cullet (CGC) mixed up with local plastic clay, sediment soil, and laterite clay. Boric oxide is also used as sintering aid. The experimental formulation is divided into 3 groups (A, B, and C) with 27 formulas. Test samples are moulded at 100 bar by Uni-axial pressing in dimension 50 x 100 x 7 mm and fried at temperature 850 °C. The initial results show that all formulas can develop marble texture and achieve Thai Industrial Standard TIS 2508-2555. Reducing firing temperature to 800 °C is the further investigation. However, formulas consisting 90% glass cullet are not selected, due to difficulty of molding workpieces. The final results of firing 800o C show that formula A6 containing 15% Plastic clay, 85% glass cullet, 2% boric oxide has the highest bending strength and lowest water absorption (<1%). Its properties are similar to formula C6 containing 15% laterite soil 85% glass cullet, 2% boric oxide. They can pass Thai Industrial Standard TIS 2508-2555 Floor Tiles BIb. Analyzing microstructure the fired specimens of these formulas by Scanning Electron Microscope has found glassy phases and dense matrix structures. Furthermore, Nepheline, Quartz, Cristobalite, Wollastonite, Devitrite, and Albite are identified by X-Ray Diffractometer. It can be summarized that marble texture surface fired clay tile can be developed by utilizing waste glass and low cost local materials.
