Problems solved by technology

[0004] However, during the hydration process of cement raw materials in concrete, alkaline substances such as calcium hydroxide will be produced, which will easily seep from the pores of the concrete structure to the surface of the concrete under the drive of water, causing efflorescence, which is not conducive to plant growth. growth

preparation example 1

[0043] Preparation example 1, a kind of organosilicon-modified acidic particles, is prepared according to the following method:

[0044] Take 0.1kg of deer marsh soil (acid granules) and add it to 5kg of hydrochloric acid solution with a mass concentration of 10%, soak for 1h, and filter to obtain pretreated granules;

[0045] Then the pretreatment particles are dispersed in 8 kg of mass concentration in 3% sodium lauryl sulfate aqueous solution (surfactant), after the dispersion is uniform, the heating is raised to 80°C, and then added in the 5wt% potassium persulfate solution ( Initiator), stir and mix, then add 1.6㎏ octamethylcyclotetrasiloxane (organosilicon monomer), keep warm for 3 hours, filter, wash, screen, and dry to obtain organosilicon modification with a particle size range of 1 to 5mm Acidic particles.

[0046] Among them, deer marsh soil was obtained from Guangzhou Wanlin Gardening Co., Ltd., with a pH value of 6 and a water absorption of 20%.

preparation example 2

[0047] Preparation example 2, a kind of organosilicon-modified acidic particles, prepared according to the following method:

[0048] Take 0.1kg of deer marsh soil (acid granules) and add it to 5kg of hydrochloric acid solution with a mass concentration of 13%, soak for 1.5h, and filter to obtain pretreated granules;

[0049] Then the pretreatment particles are dispersed in 8 kg mass concentration of 2% sodium lauryl sulfate aqueous solution (surfactant), after the dispersion is uniform, the heating is raised to 90 DEG C, and then added in the 10wt% potassium persulfate solution ( Initiator), stir and mix, then add 1.8㎏ octamethylcyclotetrasiloxane (organosilicon monomer), keep warm for 4 hours, filter, wash, screen, and dry to obtain organosilicon modification with a particle size range of 1 to 5mm Acidic particles.

[0050] Among them, deer marsh soil was obtained from Guangzhou Wanlin Horticulture, with a pH value of 6 and a water absorption of 20%.

preparation example 3

[0051] Preparation Example 3, a kind of organosilicon-modified acidic granule, differs from Preparation Example 1 in that an equal amount of peat granules are used instead of deer marsh soil; wherein, the peat granules are obtained from Qingyuan Manchu Autonomous County Biyuan Peat Development Co., Ltd., and its activated decay The content of phytic acid is greater than or equal to 20%.

Abstract

The invention discloses porous vegetation concrete and a preparation method thereof. The porous vegetation concrete comprises the following components in parts by mass: 100-130 parts of cement; 310-360 parts of coarse aggregate; 0.5-1.2 parts of a water reducing agent; 20-35 parts of water retention particles; 15-25 parts of reinforced fiber; 8-15 parts of organic silicon modified acidic particles; 50-80 kg of water; the organic silicon modified acidic particles are prepared by the following steps: soaking acidic particles in an acid solution, and filtering to obtain pretreated particles; dispersing the pretreated particles in a surfactant solution, adding an organic silicon monomer and an initiator, and reacting to obtain organic silicon modified acidic particles; the mass ratio of the acidic particles to the organic silicon monomer is 1: (13-18). According to the porous vegetation concrete, the saltpetering phenomenon on the surface of concrete can be remarkably inhibited while the strength performance of a concrete foundation is guaranteed, and the growth conditions of plants are guaranteed.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a porous planting concrete and a preparation method thereof. Background technique [0002] With the development of urbanization, public areas such as urban roads are covered with large areas of concrete. The denseness of concrete leads to its lack of water permeability and air permeability, which cannot provide the environment required for plant growth, and is not conducive to increasing the urban green area. Therefore, it is of great practical significance to develop planting concrete that can be used for plant growth. [0003] Porous planting concrete is a kind of porous structure concrete with high porosity. It reduces the density of concrete by reducing the addition of fine aggregate in concrete raw materials, thereby improving the water permeability and air permeability of the concrete structure, and providing favorable conditions for the growth of plants. condition. Porous planti...
