Abstract

The invention relates to an additive special for planting concrete and a preparation method and a using method for the additive. The preparation method comprises the following steps of: adding 45 to 55 mass percent of 20 percent polycarboxylate water reducing agent into a compound tank, adding 4 to 8 mass percent of silicon powder, 3 to 5 mass percent of NH4HCO3 and 2 to 4 mass percent of potassium dihydrogen phosphate into the compound tank, dissolving 0.1 to 0.3 mass percent of FeSO4.7H2O powder in water, diluting to obtain a 0.1 percent aqueous solution, adding into the compound tank, adding 28 to 46 mass percent of water, and uniformly stirring to obtain the additive special for the planting concrete. The using method comprises the following steps of: adding the additive in an amount which is 2 to 6 percent based on the mass of cement, continuously stirring for 1 minute, adding water, and continuously stirring for 2 to 3 minutes, so that the 28-day strength of ecological concrete is improved to 4-7MPa, the 28-day pH value is 8 to 11, and the growth requirements of vegetations can be met. The hydration reaction of the cement can be promoted, the early strength of the concrete is improved, durability is improved, the environment affinity of the ecological concrete is improved, animals, plants and microorganisms can be inhabited in the concrete conveniently, the capacity of symbiosing with organisms is improved, and the natural purification effect of water is effectively promoted.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a special additive for green ecological vegetation concrete (GCF-2) and its preparation method and use method. Background technique [0002] The current porous ecological concrete technology consists of a main structure, a vegetation substrate and plants. As the main structure of the flower carrier, it is sand-free large-porosity permeable concrete. The thickness can be designed according to requirements. In the case of ensuring the strength, when the strength is 5MPa, the porosity is 25-33%. A layer of cultivation medium and gap filling material is attached to the surface, and the flowers and grass seeds are placed in it, and given the corresponding water, they can take root and germinate. The seedlings of the plants pass through the concrete pores and take root in the soil beneath the concrete. Usually, the porous ecological concrete used is configured due to ...
