Abstract

The invention discloses an environment-friendly plant concrete, consisting of water, cement, waste concrete aggregate, concrete antalkali and poly carboxylic acid water reducing agent. The detailed matching proportion is as follows: the ratio of water/cement/ waste concrete aggregate is 0.28 to 0.32:1:5; the quantity of adopted concrete antalkali is 10 to 20 percent of the cement quantity; the quantity of the poly carboxylic acid water reducing agent is 1 to 2 percent of the cement quantity. Compared with the existing similar product of the prior technology, the invention not only can solve the contamination to ecological environment by stacked waste concrete but also can avoid the damage to ecological environment by extreme exploitation to aggregate and realize the purpose of planting plants on concrete, thus achieving the effects of recycling sources, regulating ecological balance and beautifying environment; the intensity of the concrete is high, the concrete can be pre-cast into various shapes as requirements, and the construction is convenient.

Description

Technical field: [0001] The invention relates to an environment-friendly vegetation concrete. Background technique: [0002] At present, with the increasing scale of urban residential renewal and municipal relocation, many concrete buildings and structures need to be demolished for redesign and construction, and these demolished waste concrete are often stacked in the wild without rational use, affecting the ecology The environment is not conducive to ecological balance. In addition, due to the respective characteristics of flowers and concrete, flowers and plants cannot grow on the concrete, so that the concrete on the courtyard and slope protection is not covered with plants and trees, which not only hinders the landscape, but also is not conducive to the local ecological balance. And vegetation concrete is a kind of can adapt to plant growth, has positive effect to adjusting ecological balance, beautifying the environment, realizing the coordination between human and nat...
