An Alkaline Inhibitor for Planting Concrete

Abstract

The invention provides an alkalinity inhibitor for plant-growing concrete, and belongs to the technical field of concrete inhibitors. The alkalinity inhibitor comprises 35-60% by weight of a polymer, 15-40% by weight of a permeable crystalline material and 20-30% by weight of an organosilicone hydrophobic material. By addition of the plant-growing alkalinity inhibitor, a membrane structure can be formed inside the concrete and on the surface of the concrete, and capillary apertures are closed to prevent precipitation of alkaline substances. By addition of the organosilicone, penetration of water into the concrete is prevented and the precipitation risk of the alkaline substances is reduced. The alkalinity inhibitor greatly reduces influences of the alkaline substances in soil on plant growth, thus protecting vegetation and reducing the greening cost of the plant-growing concrete. In addition, the alkalinity inhibitor can be prepared and used conveniently and is beneficial for environment protection. The alkalinity inhibitor is capable of significantly improving an alkali environment, inhibiting generation of the concrete alkalinity, and controlling the pH value of the soil.

Description

technical field [0001] The invention relates to an alkaline inhibitor for planting concrete, which belongs to the technical field of concrete inhibitors. Background technique [0002] With the continuous development of economy and society and the acceleration of urbanization, the use of concrete in our country is increasing day by day. In 2010, my country's commercial concrete consumption has exceeded 600 million cubic meters. While people are using the structural properties of concrete, they are paying more and more attention to other functions such as intelligence and ecology of concrete. Therefore, plant-growing concrete with water permeability and air permeability has emerged as the times require. Vegetative concrete belongs to porous concrete, and uses the characteristics of large pores, water permeability and air permeability of porous concrete to infiltrate the nutrients needed by plants, and fill the pores with nutrients to grow plants. Vegetative concrete can solv...
