Influence of Firing Temperature on the Pozzolanic Activity of Kaolin Wastes
The volume of waste generated by mining and mineral processing industries has escalated each day because of increased demand caused by global economic growth. The kaolin processing industries are important economic segments in the state of Paraiba, but generate huge amounts of waste. An alternative for the recycling of this waste is its use in mortars. The kaolin contained in wastes after thermal treatment can reduce the consumption of cement in the production of mortars. It was evaluated the influence of firing temperatures of the residue on its pozzolanic activity. The residue was fired at temperatures of 600°C, 700°C and 800°C for 2h and subjected to mineralogical analysis. The evaluation produced the mortar with a mixture of kaolin waste burned at temperatures of 600°C, 700°C and 800°C with lime delivering true a good mechanical performance, reaching values of compressive strength greater than the legislated.
