Abstract

The invention discloses a high-strength pavement brick. The high-strength pavement brick is prepared from the following raw materials in parts by weight: 10-20 parts of waste glass, 20-30 parts of cement, 15-25 parts of coal ash, 12-18 parts of a mineral waste residue, 7-13 parts of volcanic ash, 6-14 parts of fibrolite, 6-9 parts of nepheline, 3-7 parts of illite, 6-11 parts of pumice stone, 8-12parts of quartz sand, 5-9 parts of glass fiber, 5-10 parts of modified passion fruit shell powder, 2-4 parts of nano titanium dioxide, 3-9 parts of polyamide, 2-4 parts of a coagulant, and 1-3 partsof a water reducing agent. Through controlling a matching ratio between the raw materials, a prepared product has good mechanical property, compressive strength and breaking strength are improved, andthe product has good abrasive resistance.

Description

technical field [0001] The invention belongs to the technical field of pavement bricks, and in particular relates to a high-strength pavement brick and a preparation method thereof. Background technique [0002] With the intensification of urbanization, the urban surface is gradually being covered by buildings and various concrete and other water-repelling materials, and the proportion of impermeable areas has increased significantly, and the coverage rate in some areas has exceeded 80%. As the drainage capacity of cities is getting worse and worse, when many cities encounter heavy rains, the rainwater on the roads cannot seep quickly, which can easily cause urban waterlogging. Therefore, in order to solve the problem of urban surface hardening, create a high-quality natural living environment, and maintain urban ecological balance, a new green and environmentally friendly building material product-permeable bricks emerged as the times require and have developed rapidly. ...
