Abstract

The invention relates to a rubber noise-reduction wear-resistant road brick and a preparation method thereof, belonging to the technical field of building materials. The invention provides a rubber noise-reduction wear-resistant road brick and a preparation method thereof, wherein the method comprises the steps of: evenly mixing 10wt%-15wt% cement, 5.0wt%-10.0wt% of pulverized fuel ash, 50wt%-70wt% of broken stones and 0.12wt%-0.8wt% of rubber powder and a proper amount of water, so as to obtain a mixture in a semi-dry state for die-filling; then evenly mixing 3.0wt%-5.0wt% of white cement, 7.0wt%-12wt% of quartz sand, 0.08wt%-0.4wt% of rubber powder, more than or equal to 0.4wt% of pigment and a proper amount of water, so as to obtain a mixture in a semi-dry state for die-filling; and washing the rubber powder in advance by adopting water and alkali solution, shaping in a jolt-squeeze manner and carrying out maintenance to obtain the rubber noise-reduction wear-resistant road brick. The method is simple, the road brick has the advantages of good compressive strength, wear resistance property, impact resistance property and noise reduction effect.

Description

technical field [0001] The invention relates to a rubber noise-reducing wear-resistant pavement brick and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] At present, in order to keep the urban environment clean and beautiful, a large number of pavement bricks are laid on the ordinary ground, and the ordinary pavement bricks are mainly composed of the bottom layer and the surface layer, and the bottom layer is mainly made of raw materials such as gravel, cement and steel slag. The layer is mainly made of raw materials such as river sand, pigment and cement. For example, the Chinese patent application (publication number: CN1517317A) discloses a pavement brick made of high-strength colored rice stone. and crushed stones, the fabric layer is made of colored rice stones, and the fabric layer is consolidated on the bottom material layer. Although the pavement brick has good strength and aesthetic performance, b...
