Low-carbon energy-saving noise-reducing lightweight water-permeable brick containing bamboo aggregate and concrete

Abstract

The invention discloses a low-carbon energy-saving noise-reducing lightweight water-permeable brick containing bamboo aggregate and concrete. The water-permeable brick is composed of the bamboo aggregate and cement mortar, and specifically comprises the following components: 18.2 to 29.3 parts of Portland cement, 25.2 to 40.1 parts of modified bamboo aggregate, 13.5 to 20.8 parts of medium sand, 0.5 to 1.5 parts of a recombination admixture, and 10 to 20 parts of neutral water. The water-permeable brick has the following characteristics that the water-permeable brick is high in freezing resistance, compression resistance and corrosion resistance; the porous material, namely the bamboo aggregate is environment-friendly and renewable; the internal porosity of the water-permeable brick is high, so the problem of surface water accumulation is effectively solved, the water-permeable brick has super-strong water permeability, and meanwhile, pavement noise can be reduced by 3-5 decibels; and in addition, due to the fact that the bamboo aggregate replaces traditional stone aggregate, the brick is 30-40% lighter than a common concrete brick under the same size, and is low in price compared with similar products. The low-carbon energy-saving noise-reducing lightweight water-permeable brick containing the bamboo aggregate and the concrete can be widely applied to non-motor vehicle roads, parking lots, scenic spots, gardens, sidewalks and the like.

Description

technical field [0001] The invention belongs to the field of permeable bricks, in particular to a low-carbon, energy-saving, noise-reducing lightweight permeable brick made of bamboo aggregate concrete. Background technique [0002] With the increase in population, the deterioration of the environment, the high carbon emissions, the lack of water resources and energy sources, most of the parking lots, non-motor vehicle roads, scenic spots, gardens, sidewalks, etc. are made of granite, glazed tiles, cement and asphalt. When it rains, it will be more inconvenient for people to travel, and at the same time, it will cause water shortage in vegetation and waste of water resources. [0003] At present, the main raw materials of permeable materials such as permeable bricks and permeable pavements on the market are non-renewable mineral resources such as ceramics or concrete. In the process of raw material mining and permeable brick forming and sintering, a large amount of energy is...

Problems solved by technology

[0002] With the increase in population, the deterioration of the environment, the high carbon emissions, the lack of water resources and energy sources, most of the parking lots, non-motor vehicle roads, scenic spots, gardens, sidewalks, etc. are made of granite, glazed tiles, cement and asphalt. When it rains, it will be more inconvenient for people to travel, and at the same time, it will cause water shortage in vegetation and waste of water resources.

[0003] At present, the main raw materials of permeable materials such as permeable bricks and permeable pavements on the market are non-renewable mineral resources such as ceramics or concrete. In the process of raw material mining and permeable brick forming and sintering, a large amount of energy is consumed, a large amount of carbon dioxide is emitted, and the environmental protection is poor. It is not conducive to the realization of the goal of carbon neutrality, and at the same time, the water filtration performance is poor and the noise reduction effect is poor
