Vegetation cement soil cementing material capable of regulating and controlling pH value

Abstract

The invention relates to the technical field of building materials, and particularly discloses a plant-growing cement soil cementing material capable of regulating and controlling the pH value, which is prepared from the following raw materials in parts by weight: 7 to 15 parts of cement, 90 to 100 parts of natural soil, 25 to 35 parts of ecological modifier, 2 to 4 parts of soil stabilizer, 0.01 to 0.05 part of citric acid monohydrate and 2 to 4 parts of boric acid. The plant-growing cement soil cementing material is prepared from the L-SAC, the soil, the ecological modifier, the soil stabilizer, the citric acid monohydrate and the boric acid as raw materials, the problem that the pH value in the plant-growing cement soil is too high can be fundamentally solved, the strength, durability and plant-growing performance of the plant-growing cement soil can be improved, the plant-growing cement soil can better adapt to growth of green plants, and the plant-growing cement soil has good application prospects. And the engineering application requirements are met, and the good popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a plant-grown cement-soil cementitious material capable of regulating pH value. Background technique [0002] Plant-grown cement-soil is a new type of environmental protection material composed of sand-free porous concrete, nutrient soil, and topsoil. Planted cement soil has good water permeability, can adapt to the growth of green plants, enhance the exchange of moisture and heat on the surface, and adjust the groundwater level. [0003] The pH value of vegetative cement soil suitable for plant growth is between 3.5 and 9.5, while the pH value inside the vegetative cement soil prepared from ordinary Portland cement is as high as 12 to 13, which cannot meet plant growth. At present, there are physical methods, chemical methods, structural methods, biological methods and agronomic methods to control the pH value of plant-cement soil. Among them, the physical method is...
