Problems solved by technology

[0003] Ordinary planting concrete is made of natural or recycled concrete aggregates, which has a large bulk density and cannot float on the water surface, so it is difficult to apply in water to improve water quality
Secondly, the slurry coating layer of ordinary planting concrete is brittle and shrinks greatly, and the slurry coating layer is easy to form cracks; when water flows through, the hydration products in the concrete decompose and lose, the concrete is corroded, and the strength decreases, which affects the working performance and service of planting concrete age

Abstract

The invention provides floating type plant-growing concrete as well as a preparation method and application thereof in water purification. The floating type plant-growing concrete comprises a concrete base body and a plant-growing matrix. The concrete matrix is prepared from the following raw materials in parts by weight: 60 to 150 parts of low-alkalinity sulphoaluminate cement, 10 to 40 parts of fly ash, 5 to 20 parts of modified rubber powder, 240 to 450 parts of ceramsite, 1 to 4 parts of a water reducing agent and 20 to 60 parts of water; wherein the low-alkalinity sulphoaluminate cement, the fly ash and the modified rubber powder are cementing materials, and the ceramsite is coarse aggregate.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a floating type planted concrete and a preparation method thereof. Background technique [0002] Planted concrete refers to a type of concrete or concrete in which a special concrete with a certain pore size and a certain porosity is used as the skeleton, and the material required for plant growth is filled in the concrete pores. product. It is a kind of concrete that can plant green plants, slope protection plants, etc. On the premise of maintaining the original functional advantages of concrete, ecological functions are added, such as greening, soil conservation, energy exchange, etc. [0003] Ordinary planted concrete is made of natural or recycled concrete aggregates, which has a large bulk density and cannot float on the water surface, so it is difficult to apply in water and improve the water quality. Secondly, the slurry coating of ordinary planted concrete is...
