Light environmental-friendly brick based on building waste and production process of light environmental-friendly brick

Abstract

The invention discloses a light environmental-friendly brick based on building wastes and a production process of the light environmental-friendly brick. The light environmental-friendly brick comprises the following raw materials in percentage by weight: 30-50% of water, 15-25% of Portland cement, 5-15% of a ceramic waste, 5-15% of a brick waste, 6-8% of river sand, 3-7% of bits of wood, 3-7% offurnace cinder and 2-4% of modified foaming aids. Due to adoption of the ceramic waste, the brick waste, the bits of wood and the furnace cinder in the raw materials, building wastes and slag materials can be reasonably recycled, environment influence caused by casual treatment can be avoided, the production cost can be reduced, and meanwhile the environment protection is greatly improved; and dueto adoption of the modified foaming aids, under coactions of final products, namely calcium dodecyl benzene sulfonate and sodium dodecyl benzene sulfonate generated in mutual reactions of raw materials in the modified foaming aids, and under the synergetic effect of a silicon resin polyether emulsion, a foaming effect is improved, and the consequence that bricks have unequal and too large self weights since air pores are unequal in size and non-uniform in distribution can be avoided.

Description

technical field [0001] The invention relates to the technical field of bricks and tiles, in particular to a lightweight and environmentally friendly bricks and tiles based on construction waste and a production process thereof. Background technique [0002] In recent years, the amount of generation and discharge of urban garbage is constantly increasing. While enjoying urban civilization, people are also suffering from the troubles caused by urban garbage, of which construction waste occupies a considerable proportion, which undoubtedly aggravates the Contradictions between the environment, people and resources are not conducive to the governance of the environment and the long-term development of the construction industry. At the same time, the quality of bricks and tiles used in construction is attracting more and more attention. [0003] However, in the production process of the existing bricks and tiles for construction, there is a problem of poor foaming effect, which o...

Problems solved by technology

[0002] In recent years, the amount of generation and discharge of urban garbage is constantly increasing. While enjoying urban civilization, people are also suffering from the troubles caused by urban garbage, of which construction waste occupies a considerable proportion, which undoubtedly aggravates the Contradictions between the environment, people and resources, and it is not conducive to the governance of the environment and the long-term development of the construction industry. At the same time, the quality of bricks and tiles used in construction is attracting more and more attention.

[0003] However, in the production process of the existing bricks and tiles for construction, there is a problem of poor foaming effect, which often leads to uneven and excessive self-weight of the bricks and tiles due to the unequal size and uneven distribution of the pores, which greatly affects the At the same time, in the production process of the existing building bricks and tiles, it is difficult to fully maintain them, making the bricks and tiles prone to deformation or cracks during use, which greatly reduces the normal service life of the bricks and tiles ; and in the production process of the existing building bricks and tiles, the mixing effect of the mixing equipment is often poor and it is easy to cause incomplete mixing and uneven mixing between the raw materials, which will affect the product quality
