Recycling of Mine Wastes as Ceramic Raw Materials: An Alternative to Avoid Environmental Contamination

Solid waste management has moved to the forefront of the environmental agenda. Nations are considering restrictions on packaging and controls on products in order to reduce solid waste generation rates. Local and regional governments are requiring wastes to be separated for recycling, and some have even established mandatory recycling targets. However, industrial and everyday activities continu...

construction wastes as raw materials for geopolymer binders

it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...

FABRICATION AND CHARACTERIZATION OFHIGH PERFORMANCE CERAMIC MEMBRANE HAVINGNANOMETRE PORES

Abstract: In this study, carbon nanotubes (CNTs) were grown directly in the pores of micro porous pyrex membranesand consequently ceramic membranes with very fine pores and high porosity were achieved. Our experiment was donein two stages. Initially cobalt powder with different percent was homogeneously mixed with pyrex powder. In order toproduce row membranes, each of these mixtures were compa...

Numerical Simulation of Fabrication for Ceramic Tool Materials

Respiratory toxicity of raw materials used in ceramic production.

The main purpose of this study was to assess the pulmonary reactions associated with exposure to raw materials used in ceramic production (RMCP). This was a cross sectional study in which 33 male workers with current exposure to RMCP and 20 healthy male unexposed workers (referent group) were interviewed and respiratory symptom questionnaires were administered to them. Furthermore, they underwe...
