Embodiment 1

[0040] Processing of rockery:

[0041] (1) Mold making: the mold includes an outer mold and an inner mold, and the mold is made according to the established rockery structure;

[0042] (2) Mixing materials: 60kg blast furnace expanded slag of 80 meshes, 30kg Class I fly ash, 20kg Portland cement, 13kg lignocellulose, 10kg asbestos wool, 3kg cement additive hydrolyzed polymaleic anhydride, 5kg binder Styrene-butadiene copolymer and 5kg lubricant talcum powder are added in the mixer, mixed for 10min at a rotating speed of 800r / min, and mixed evenly to obtain the rockery processing material;

[0043] (3) Pouring: import the above-mentioned materials into the mold, insert the vibrating rod into the mold, vibrate and tamp the material, and replenish the material until the material is tamped and flush with the mold opening;

[0044] (4) Demoulding: The material is cured and molded for 48 hours under natural conditions at 25°C, and the outer mold and the inner mold are separated to ...

Embodiment 2

[0047] The difference between embodiment 2 and embodiment 1 is the change of raw material consumption.

[0048] Processing of rockery:

[0049] (1) Mold making: the mold includes an outer mold and an inner mold, and the mold is made according to the established rockery structure;

[0050] (2) Mixing materials: 55kg blast furnace expanded slag of 80 meshes, 32kg Class I fly ash, 22kg Portland cement, 12kg lignocellulose, 10kg asbestos wool, 3kg cement admixture hydrolyzed polymaleic anhydride, 5kg binder Styrene-butadiene copolymer and 4kg lubricant talcum powder are added in the mixer, mixed for 10min at a rotating speed of 800r / min, and mixed evenly to obtain the rockery processing material;

[0051] (3) Pouring: import the above-mentioned materials into the mold, insert the vibrating rod into the mold, vibrate and tamp the material, and replenish the material until the material is tamped and flush with the mold opening;

[0052] (4) Demoulding: The material is cured and mo...

Embodiment 3

[0055] Taking Example 1 as a comparison, the cement admixture is set to replace the hydrolyzed polymaleic anhydride with an equivalent amount of polyaspartic acid in Example 3, and the rest of the processing operations are exactly the same as in Example 1.

Abstract

This invention discloses a garden rockery that is conducive to the cultivation of green plants and its processing method, relating to the field of rockery processing technology. It is made from the following raw materials in parts by weight: 30-80 parts of blast furnace expanded slag, 10-50 parts of fly ash, 10-50 parts of silicate cement, 5-20 parts of lignocellulose, 5-20 parts of asbestos wool, 1-10 parts of cement admixture, 1-10 parts of binder, 1-10 parts of lubricant, and 100-200 parts of water. This invention uses industrial waste blast furnace expanded slag and fly ash as the main materials, and uses silicate cement and other auxiliary materials to make rockeries. It not only realizes the rational reuse of industrial waste blast furnace expanded slag and fly ash, but also produces rockeries with good appearance quality, strong environmental protection, and excellent compressive strength, which is conducive to the cultivation of large and medium-sized green plants on the rockery.

Description

Technical field: [0001] The invention relates to the technical field of rockery processing, in particular to a garden rockery beneficial to the cultivation of green plants and a processing method thereof. Background technique: [0002] Rockery is a mountain built with soil, stone and other materials for the purpose of landscaping in the garden. Rockery has various landscaping functions, such as forming the main landscape or terrain skeleton of the garden, dividing and organizing the garden space, arranging courtyards, revetments, slope protection, soil retaining, and setting up natural flower beds. It can also be combined with garden buildings, garden roads, sites and garden plants to form a changing landscape, so as to reduce the artificial atmosphere, add natural interest, and make the garden buildings blend into the landscape environment. Therefore, rockery has become one of the characteristics of Chinese natural landscape gardens. [0003] The development of modern gar...
