Reutilizing Sediment Soil Wastes from Water Supply Treatment Process as Replacement Materials of Non-Fired Wall Tiles

Abstract

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.

Eco-Friendly Innovation of Non-Fired Ceramic Tiles from Rice Husk Ash and Recycled Glass Cullet

“…The control formula consisted of river sand (RS), ordinary Portland cement (OPC) type I, and laterite soil (LS) (containing 15% RS, 22.5% OPC, and 62.5% LS) was derived from Wangrakdiskul and Neamlut [15]. The experiment was conducted from the control formula by mixing rice husk ash Composite Materials and Material Engineering V (RHA), green glass cullet (GGC), and local kaolin clay (LKC) that divided into three groups; A (0% RHA), B (5% RHA), and C (10% RHA), as illustrated in Table 3.…”

“…Wangrakdiskul and Neamlut also concluded that used 5% sediment soil as replacement fluvial sand of non-fired tiles. The bending strength was 7.63 MPa at 60 days of curing that can pass water absorption of Thai Industrial Standard (TIS 2508-2555) [15].…”

“…For improving the modulus of rupture of non-fired tiles, the present work has used the control formula from previous work [15] but utilizing other waste materials. This paper aimed to investigate the new eco-friendly product for reducing energy consumption and utilizing wastes of rice husk ash from the biomass power plant and green glass cullet from recycling factory which mixed local kaolin clay from Prachinburi province for producing non-fired ceramic tiles as compared to control formula.…”

Enhancement Bending Strength of Non Fired Wall Tiles by Recovering Sand-Wastes By-Products from Kaolin Beneficiation Process

“…Investigation for using sediment soil from water supply process was studied by Wangrakdiskul& Neamlut (2018). Valorizing 10% of sediment soil wastes has resulted 7.51 MPa of bending strength, and 6.87% water absorption curing period for 60-day aging [11].…”

Clay Tiles Production Using Palm Ash, Spent Bleaching Earth, and Palm Fiber as Substitute Materials

“…The crystalline phase of raw materials was investigated. The CT qualities were examined according to the Thai industrial standard (TIS 2398 and 2508) [13,14] with the properties of water absorption, bulk density, acid corrosion and transverse breaking strength (TBS).…”
