Abstract

Abstract

In order to improve the mechanical properties and water permeability of permeable brick, and find a way for the comprehensive utilization of iron tailings, a new type of glass permeable brick was developed with the main raw material of iron tailings. The basic glass was melted by iron tailings, and the sintering temperature was determined according to DSC analysis results of the basic glass. The basic glass was divided into 5 groups according to particle size and sintered to obtain glass permeable brick samples. The compressive strength, permeability coefficient and water retention of the samples were tested and analyzed. The results showed that the various performance indexes of the sample were ideal with the basic glass particle size of 4~2.23 mm and the sintering temperature of 760~810℃. The compressive strength of the samples was 24 MPa. The water permeability coefficient was 1.06~0.98 cm/s, and the water retention was 0.9~0.4 g/cm. Glass permeable owns the greater compressive strength as well as good permeability simultaneously, which has a good prospect of popularization and application.
