摘要:
为提高透水砖的力学性能与透水性能，同时为铁尾矿综合利用寻求一条有途径，以铁尾矿为主要原料，研发出一种新型玻璃透水砖。用铁尾矿熔制基础玻璃，参照基础玻璃DSC分析结果制定烧结温度，将基础玻璃按照粒度大小分成5组进行烧结得到玻璃透水砖试样。对试样的抗压强度、透水系数、保水性做测试分析。结果表明，当基础玻璃粒度为4~2.23 mm、烧结温度为760~810℃时，试样各项性能指标较为理想。此时试样的抗压强度为24 MPa，透水系数为1.06~0.98 cm/s，保水性为0.9~0.4 g/cm。玻璃透水砖可以同时具备较大的抗压强度和良好的透水性，有很好的推广应用前景。
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.
