The invention discloses a high-strength heat-insulation brick comprising the following raw materials in percentage by mass: 5-12% of 425 portland cement, 5-20% of river sand, 23-36% of glass beads, 12-25% of coal ash, 10-18% of tailing sand, 10-14% of asbestos fibers, 1.2-1.5% of a foaming agent and 14-28% of water. The raw materials adopted by the high-strength heat-insulation brick are wide in source, and no organic volatile substances are adopted, so that not only is the material cost reduced, but also the environment pollution is avoided. The high-strength heat-insulation brick has the characteristics of high compressive strength, low heat conductivity coefficient, good heat insulation property, good fireproof performance, good water resistance, good weather resistance and the like.
