Abstract

The invention relates to the fields of ecological remediation and sponge urban construction and discloses carbon-fixing vegetation concrete. The carbon-fixing vegetation concrete is prepared from thefollowing raw materials in parts by weight: 100 parts of cement, 410-450 parts of aggregates, 30-50 parts of a carbon-fixing greening additive, 30-40 parts of water and 0.5-0.9 part of plant seeds, wherein the carbon-fixing greening additive is composed of sludge charcoal, edible mushroom stick, nitrogen phosphorus and potassium complex fertilizer, AM fungus fertilizer and a water-retaining agent.The compressive strength of the carbon-fixing vegetation concrete disclosed by the invention is 8.2MPa-9.6MPa; an apparent pore diameter required by growth of plant roots and survival of small animals, namely, ecological pore diameter, is 0.37mm-0.45mm; the volume ratio of ecological void to ecological concrete, namely, ecological void ratio, is 31%-36%; the survival rate of seeds is high; afterthe seeds survive, the greening rate of the concrete after half a year is 95%-99%.

Description

technical field [0001] The invention relates to the fields of ecological restoration and sponge city construction, in particular to a carbon-fixing vegetation concrete. Background technique [0002] Vegetation concrete is a kind of concrete and its products developed on the basis of traditional concrete that can adapt to plant growth, have potential functions such as greening, purification, and water seepage. It is also commonly called planting concrete, greening concrete, ecological concrete, ecological concrete and vegetation concrete etc. In recent years, with the advancement of my country's ecological protection and restoration, sponge city construction and other work, vegetation concrete has received unprecedented attention. [0003] Unlike traditional concrete, in the preparation process of vegetation concrete, in addition to strictly controlling the amount of fine aggregate and cementitious materials to form connected pores to ensure that plant roots can penetrate an...
