Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the cold and frost resistance of green vegetation concrete is relatively poor. Under low temperature conditions, the moisture in green vegetation concrete will freeze, and the frozen green vegetation concrete will be more likely to produce cracks, resulting in concrete cracks. Structural damage, thus affecting the service life of green vegetation concrete

Abstract

The invention relates to the field of concrete, and particularly discloses anti-freezing green vegetation concrete and a preparation method thereof.The anti-freezing green vegetation concrete is prepared from, by weight, 200-300 parts of cement, 60-80 parts of kieselguhr, 300-380 parts of aggregate, 60-100 parts of soil, 10-20 parts of composite fibers, 1-2.5 parts of air entraining agent, 4-10 parts of water reducing agent and 120-160 parts of water; the air entraining agent is prepared from the following components in parts by weight: 20 to 35 parts of rosin powder, 8 to 14 parts of nekal, 12 to 16 parts of melamine, 5 to 15 parts of sulfuric acid, 10 to 20 parts of sodium hydroxide and 12 to 18 parts of polyethylene glycol. The anti-freezing green vegetation concrete disclosed by the invention has relatively good anti-freezing performance.

Description

Technical field [0001] The present application relates to concrete fields, and more particularly, it involves an antifreeze green vegetation concrete and a preparation method thereof. Background technique [0002] Slope projects in urban construction provide a certain guarantee for the flood control of the city. Concrete is used in a large amount of concrete in traditional water conservancy slope, and concrete can enhance the strength of the slope, so that the slope is less likely to be depressed, collapse, but the concrete will also hinder the growth of vegetation, thus affecting the surrounding ecological environment. Green vegetation concrete is an ecological concrete material developed based on the concept of environmental protection. This concrete can protect the slope in urban slope, and the plant will restore growth, and the role of plant landscape. . [0003] The main practice of existing vegetation concrete sliding techniques is to mix concrete and plant seeds into a spr...
