Water permeable brick for urban road paving and preparation method thereof
The invention relates to a water-permeable material, in particular to a high-strength water-permeable brick for urban road paving and a preparation method of the high-strength water-permeable brick. The water permeable brick is prepared by stirring and mixing active slag powder, iron tailing slag, rare earth inorganic mineral glue and a rare earth additive, and then preparing the high-strength water permeable brick for urban road paving through a specially-made brick making machine. The high-strength water permeable brick has the characteristics: the compressive strength can reach 11.5 MPa within 10 hours, the breaking strength can reach 3-3.5 MPa, and the water permeability coefficient can reach 1.2-2.0 mm/s.
本发明涉及透水材料，具体涉及一种用于城区道路铺设的高强度透水砖及其制备方法。该透水砖由活性矿渣粉、铁尾矿渣、稀土无机矿物胶、稀土外加剂搅拌、混合后，通过特制的制砖机械可制得城区道路铺设的高强度透水砖。此高强度透水砖具有以下特点：抗压强度10小时内可达11.5MPa，抗折强度可达3‑3.5MPa，透水系数可达1.2‑2.0mm/s。
