Additive applicable to plant-growing concrete and with low alkali, high strength and large porosity

Abstract

The invention discloses an additive applicable to plant-growing concrete and with low alkali, high strength and large porosity. The additive is prepared from the following components in parts by weight: 45 to 47 parts of polycarboxylic type water reducer powder, 1.6 to 3 parts of iron powder, 18 to 22 parts of fibers, 2.7 to 3.5 parts of modified starch, 12 to 14 parts of aloe powder, 1.8 to 2.5 parts of mirabilite and 12.3 to 15 parts of silicon powder. The invention aims at providing the additive applicable to the plant-growing concrete and with low alkali, high strength and large porosity;the inner alkaline environment and the porosity of the plant-growing concrete are improved and the survival rate of ecological concrete slope protection plants is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures in building materials, and in particular relates to a low-alkali, high-strength porosity admixture suitable for vegetative concrete. Background technique [0002] Concrete is the most consumed building material in various projects in the world. It has the characteristics of good economy and excellent performance, and has made great contributions to the development of human economy and society. However, it cannot be ignored that traditional concrete has also shown obvious However, it is difficult to achieve the balance of high strength, high durability and environmental friendliness. At the end of the 20th century, the concept of plant-grown concrete was first proposed by the Japan Engineering Association. Since then, plant-grown concrete has been widely used in developed countries such as Japan, Europe and the United States. Vegetative concrete slope protection has the advantages of g...
