Utilization Of Ceramic Waste By Using It As Special Concrete Aggregate

In the article is presented the method ofutilization of ceramic waste by using it as special concrete aggregate for special high temperature resistant concentrates. The research was performed on six empirically designed concrete mixtures of three on aluminous cement with simultaneous aerification with using air entraining admixture respectively at 0, 5 and 10%. In order to compare the results, three Portland cement concrete mixes were prepared which had exactly the same aerification of the mixture. All types of samples were made using recyclable aggregates of sanitary ceramics selected and crushed to 0-4 mm and 4-8 mm. This particular type of aggregate, as proved in previous authors' workshowed very favorable features in terms of the influence for thermal loads. Selected samples were subjected to a thermal treatment according to the standard curve "temperature-time" for 120 minutes until the furnace chamber temperature reached approximately 1050 degrees C. With interative concrete mixture method design, assuming that the mixture substrates were limited to the commonly used cements and the appropriate amount of air entraining admixture, there were received tight concrete with high strength parameters, which also demonstrates resistance explosive concrete particles' chipping off under conditions of high temperatures.
