Abstract

The invention discloses a plant-growing type eco-concrete. The plant-growing type eco-concrete consists of a concrete framework structure and a culture medium, wherein the concrete framework structure mainly comprises cement, water, rock ballasts and a water reducing agent, the weight ratio of the cement to the water to the rock ballasts is 1:0.28-0.45:4-6.5, and the added amount of the water reducing agent is 1 to 3 percent of that of the weight of the cement; and the culture medium consists of natural soil, a water retention agent and a sustained-release fertilizer in a weight ratio of 1:0.1-0.2:0.01-0.015. A preparation method of the plant-growing type eco-concrete comprises the following steps of: manufacturing the concrete framework structure; maintaining the concrete framework structure; filling the culture medium; sowing grass seeds; covering and compacting the culture medium on the surfaces of the grass seeds; putting precast blocks in a place to be paved; and maintaining the precast blocks until root systems of the grass seeds grow into the soil under the concrete. Compared with the prior art, the plant-growing type eco-concrete has simple materials and a simple structure, and the preparation method is simple and easy to control.

Description

technical field [0001] The invention relates to a vegetation concrete, in particular to an environment-friendly vegetation type ecological concrete and a preparation method thereof. Background technique [0002] For a long time, concrete has brought convenience to people's lives, but also caused obvious damage to the environment on which human beings live. Concrete structures destroy the natural ecological environment, destroy the habitats of animals and plants, and at the same time cause ecological deserts, on which organisms cannot grow (except bryophytes), which is easy to form an urban heat island effect. In addition, concrete structures do not have the function of maintaining soil and water, which is easy to cause soil erosion. Therefore, the research on environment-friendly ecological concrete also emerges as the times require. [0003] The research on ecological concrete started earlier in foreign countries, especially in Japan. As early as 1994 to 1995, the Japan ...
