Vegetation-form green ecological concrete, and preparation method thereof
The invention provides a vegetation-form green ecological concrete and a preparation method thereof. The vegetation-form green ecological concrete comprises 3.75 to 4 parts of water, 7 to 9 parts of Portland cement P.O42.5R, 80 to 90 parts of single-grade broken stone of 10 to 25mm, 1 to 1.25 parts of silica fume, 2 to 2.5 parts of fly ash, and 0.0006 to 0.00125 parts of an air entraining agent. The preparation method comprises following steps: Portland cement P.O42.5R, silica fume, and fly ash are mixed, and an obtained mixture is stirred for 60s; single-grade broken stone is added, and stirring is carried out for another 60s; a half of weighed water is added into an obtained mixed material, and stirring is carried out for 30s, and then the left water and the air entraining agent are added into an obtained product, and stirring is carried out for another 60s; and at last an obtained mixed product is delivered into a die, and is subjected to vibration puddling, curing, and demoulding.
