A kind of water-retaining light grass-planting brick and its making method

Abstract

The invention discloses a water-retention light grass planting brick and a production method thereof. The water-retention light grass planting brick is prepared from raw materials in parentage by mass as follows: 5%-75% of lightweight aggregate, 1%-75% of clay particles made of waste clay bricks, 1%-15% of glass fibers or plant fibers and 5%-20% of cement. Urban building waste bricks and light building materials are used effectively, the water-retention light grass planting brick with good water permeability, air permeability, water retention and strength is obtained, diameters of the lightweight aggregate and the clay particles mostly range from 2 mm to 10 mm, more gaps are provided by the grass planting brick for water permeation, harm to grass roots by water accumulation in a rainy season and ice accumulation in early freezing period is avoided, about 20% of the water retention function of the clay bricks and the aggregate can be kept, and certain moisture can be effectively retained for drought resistance of turf. Therefore, landscaping of a sponge city and recycling of building waste residues are facilitated, and the requirement for reduction of building temperature in summer is met through grass planting and landscaping on roofs.

Description

technical field [0001] The invention relates to a landscaping material, in particular to a water-retaining lightweight grass-planting brick and a manufacturing method thereof. Background technique [0002] In our country, the annual urban construction takes up a lot of green land and increases the temperature of the city. In order to comply with the development requirements of my country's ecological civilization construction sponge city, it is imminent to protect the urban environmental ecology and water ecology. [0003] In April 2012, in the "2012 Low-Carbon City and Regional Development Science and Technology Forum", the concept of "sponge city" was first proposed; The connotation, approach and prospect of city (LID) gives a clear definition of the concept of "sponge city", that is, a city can be like a sponge and has good "elasticity" in adapting to environmental changes and dealing with natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies w...

AI Technical Summary

Problems solved by technology

In the process of sponge city construction, it is necessary to increase a large number of green areas to reduce the thermal conductivity of the city. However, at present, urban construction is occupied by a large number of buildings, and it is difficult to meet the needs of sponge city construction.
