Abstract

The invention relates to the technical field of building materials and particularly relates to a baking-free pavement brick added with hydrophobic modified glass fibers. The pavement brick contains the following components: steel slag coarse aggregates, granite aggregates, cement, quartz sand, red mud, coal gangue powder, potassium feldspar powder, hydrophobic modified glass fibers, a sealing curing agent, a water reducing agent and water, wherein the hydrophobic modified glass fibers are glass fibers which are subjected to surface hydrophobic modification, the particle sizes of the steel slagcoarse aggregates are 2mm-4mm, the particle sizes of the granite aggregates are 1mm-2mm, and the fineness of quartz sand is 100-150 meshes; the cement is Portland cement, aluminate cement or magnesium oxychloride cement; and the water reducing agent is a polycarboxylic acid water reducing agent or a naphthalene water reducing agent. A manufacturing process of the pavement brick is energy-saving,environment-friendly and low in cost, and a brick body is high in rigidity and compression strength and unlikely to crack.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a burn-free pavement brick added with hydrophobically modified glass fibers. Background technique [0002] Pavement brick is a kind of paving material, which is made of cement, stone and sand, and shaped by vibration, and the surface is cut into stripes or squares. It looks exactly like granite, some are elegant and rough, some are romantic and soft. It is the pavement decoration material of choice for contemporary people. Pavers can be surfaced or uncoated; natural or colored. Including other product materials used to lay urban road sidewalks and urban squares. [0003] With the continuous development of urbanization, more and more land is used to build high-rise buildings and roads. Hardened roads and building land are usually impervious to water, so poor drainage often occurs in cities during heavy rains in summer and road water problems. In recent years, in or...
