Abstract

In recent decades the production of chemically bonded refractory materials has been clearely increased. In this paper was examined the added amount effection of 50% solution of mono aluminum phosphate (MAP) as a binder in refractory concretes. Quartz, sand and chamotte are used as fillers. Research has shown that the bond between the filler and the binder is not possible at normal temperatures if binding accelerator is not added to the mixture. As a binding accelerator in this paper was used illite-kaolinite clay in the maximum possible amount of 32%. Prepared samples are cylindrical with a diameter of 50 mm and 50 mm high. The prepared samples were dried for 24 hours at room temperature, and then heat treated at temperatures of 120°C, 800°C and 1000° C for a period of 5 hours. Heat treatment at 1000°C is continued in the same time interval of 2, 4 and 6 cycles. Heat treated samples are determined with physical properties in course which it is possible to determine the achieved quality. The following characteristics are examinated: density, apparent porosity, compressive strength and shrinkage by methods that are practiced by the control of ceramic products.
