Road brick with functions of absorbing sound and reducing noise and preparation method thereof

Abstract

The invention discloses a road brick with functions of absorbing sound and reducing noise. The road brick is prepared from the following raw materials in parts by weight: 10-20 parts of vermiculite, 15-25 parts of expanded perlite, 20-30 parts of modified light calcium carbonate, 18-27 parts of cement, 13-19 parts of silica fume, 6-12 parts of barite powder, 4-7 parts of white mica, 7-11 parts ofshale rock, 3-5 parts of tourmaline powder, 2-4 parts of nano titanium dioxide, 3-8 parts of polypropylene fiber, 1-2 parts of cellulose ether, 1-3 parts of dispersing agent, and 2-4 parts of binder.The types of the raw materials and the proportion of the materials are controlled, so that the road brick with functions of absorbing sound and reducing noise is prepared by a simple process easy to operate, a prepared product has good water permeability and high compressing strength and breaking strength, can absorb sound and reduce noise, and lowers the impact of the noise on daily life of residents along a road.

Description

[0001] technical field [0002] The invention belongs to the technical field of pavement bricks, and in particular relates to a pavement brick with sound-absorbing and noise-reducing functions and a preparation method thereof. Background technique [0003] With the variation of the global climate, the rainy season will gradually increase. However, the permeable pavement bricks of the prior art cannot remove rainwater to the drainage system in time, and once a heavy rain falls, it will cause local waterlogging and endanger road traffic safety. The research and development of my country's permeable pavement bricks is relatively late. First, the quality is uneven, the strength is not high, the water permeability is not good, and the compressive and flexural strength is low, which seriously restricts the development of my country's municipal construction; the other is the existing technology of permeable pavement bricks The sound absorption effect is not good, which affects t...

However, the permeable pavement bricks of the prior art cannot discharge rainwater to the drainage system in time. Once a heavy rain comes, it will cause local waterlogging and endanger road traffic safety.

However, the research and development of permeable pavement bricks in my country is relatively late. First, the quality is uneven, the strength is not high, the water permeability is not good, the compressive strength and flexural strength are low, which seriously restricts the development of municipal construction in my country; the other is the permeable pavement bricks of the existing technology The sound absorption effect is not good, which affects the daily life of residents along the road
