Abstract
The composition of environment-protecting green vegetation concrete is formed from cement, broken stone, water reducer, acid polymer, chemical fibre and water, its mixing ratio is as follows: water, cement; broken stone is 0.25-0.29:1:4.45; addition amount of water reducer is 3%-5% of cement weight, acid polymer is 10%-20% of weight of water, and for each cubic meter of concrete 0.9-1.2 kg of chemical fibre can be added. Said invented green vegetation concrete can be used for protecting and greening river embankment, lake embankment, building wall and roof. The compression strength of said invented green vegetation concrete can be u pto 15 Mpa-18 Mpa.
Description
Technical field [0001] The invention relates to a vegetation concrete, in particular to an environment-friendly green vegetation concrete. Background technique [0002] At present, more than 80% of the urban surface is covered by the concrete pavement of the building. This dense concrete lacks air and water permeability, and has poor ability to adjust the temperature and humidity of the air. The temperature in the urban area is 2 to 3°C higher than that in the suburbs and rural areas, causing the so-called "thermal conductivity phenomenon." Rainwater cannot seep into the ground for a long time, causing the city's groundwater level to drop, affecting the growth of plants on the ground, and the urban green area is small, resulting in an imbalance of the urban ecosystem. In addition, the texture of concrete is brittle and hard, the surface is rough and strongly alkaline, and the tactile effect is poor. At the same time, the color of concrete is dark and the visual effect lacks vital...
