Abstract

The invention discloses a greening brick which comprises desert sand grains, bentonite, zeolite powder, modified borax, a humectant, a gelling agent, a reinforcing agent, activated carbon, a curing agent and nano boron nitride powder. The preparation method of the greening brick comprises the following steps: preparing a base material, preparing an additive, preparing a mixture, pressing the mixture to obtain a pressed primary greening brick, carrying out low-temperature plasma treatment, carrying out microwave irradiation treatment, and maintaining. According to the preparation method, the air permeability of the greening brick can be improved, high strength, good water resistance and rapid curing of the greening brick are guaranteed, and meanwhile the water retention capacity of the greening brick is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a greening brick and a preparation method thereof. Background technique [0002] With the continuous development of the current social economy, the ecological environment has been destroyed, grasslands and forests have gradually degraded, and environmental issues such as desertification have attracted everyone's attention. Due to the special climatic conditions in desert areas, it is difficult to achieve ecological reversal purely relying on natural restoration, and the ecological environment must be transformed through human intervention. At present, there are mainly three methods of desert control at home and abroad: engineering sand fixation, biological sand fixation, and chemical sand fixation. [0003] Engineering sand fixation is also called mechanical sand fixation. Physical and mechanical methods are used to block the movement of quicksand. Generally, sand bar...
