Thermo Physical Characteristics of Vitrified Tile Polishing Waste for Use in Traditional Ceramics-an Initiative of Cgcri, Naroda Centre

Abstract

This paper reports the thermo physical characteristics of Vitrified tile polishing waste materials. As such growing production of vitrified tiles in the country generate large volume of this waste obtained during processing, polishing and cutting of the vitrified tiles to the tune of nearly 10-15 tonnes per day from each plant. The characteristic features of these materials are being studied and investigated to develop suitable technology for finding its gainful use especially in the traditional ceramics. It is known that ceramic as such building materials industry could be a large raw materials consumer and being heterogeneous and thus could utilize this vast quantity as the raw materials. However, the main problem would be it's firing nature as it showed thermal deformation after a particular temperature. Interestingly, the production process of most of the traditional ceramics follows a similar pattern starting from the raw materials processing up to a level of firing. Hence, to suggest suitable utility in the traditional ceramics as raw materials, it was the prime requisite that these waste must be thoroughly studied w. r. t various thermo physical characteristics to make use in this sectors. Hence, the present paper interestingly gone up to various study such as raw materials nature, particle size distribution, chemistry, XRD and DTA study for understanding typical physico chemical properties, and finally thermal properties to make it suitable for use in traditional ceramic industries. The higher fineness of the waste materials indicates its usefulness without extra grinding. The chemistry of typical sludge shows contamination from abrasive particles, sorrel cement bonding materials etc. originated from the polishing wheel and needs special precaution while suggesting use in the ceramic sectors. The firing characteristics of the sludge materials produces a foamy and spongy shapes and this could be the main guiding parameters in selecting the end use of the waste materials w. r. t temperature. The present study only shows various characteristic features of this waste and focuses its important properties to be used as a raw material in large quantity in the ceramic industries.

The Effect of Raw Materials on Some Physical Properties of Osun State Ceramic Tiles

“…Thirty number blends that comprise less than three materials were neglected since ceramic is described as a triaxial blend product [1,8,9,13,21,24]. Twenty-six other blends which have less than 50% clay proportion were also ignored since clay is the predominant material in ceramic tile production [1,2,6,7,15,[24][25][26][27]. After forming, the samples were dried by convection in an open laboratory drying oven (model DHG-9101-2A manufactured by Searchtech Instrument) where heated air was circulated around the ceramic samples.…”
