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] In the construction of water conservancy projects, the use of concrete slabs to protect river embankments is an effective method, especially in the construction of urban flood control and diversion channel projects in recent years, most of which have adopted this method. However, this method is at the cost of the destruction and deterioration of the natural environment. The large area of rigid walls made of concrete slabs has no grass growing and is barren and the natural environment has deteriorated. Environmentally friendly green vegetation concrete is a kind of concrete that has just started research at home and abroad in recent years, which can ensure the growth of plants. But so far, the existing green vegetation concrete has low compressive and flexural strength, generally around 10Mpa, which is difficult ...
