preparation example Construction

[0021] A method for preparing artificial landscape stone regenerated from construction waste, characterized in that it comprises the following steps:

[0022] (1) Use channel steel or angle steel to make the bracket of the landscape stone, then use steel bars to make a skeleton according to the shape of the landscape stone and weld it to the outside of the bracket, and cover the skeleton with a layer of steel wire mesh substrate to form the keel of the landscape stone;

[0023] (2) After brushing the mold box with a layer of release agent, fix the processed landscape stone keel into the mold box;

[0024] (3) After adding water to the mixer, add recycled construction waste fine aggregate, recycled construction waste coarse aggregate, construction waste dust, Portland cement, artificial sand, and granite stones into the mixer and stir for 3-5 minutes, then pour into the mold;

[0025] (4) Put the poured mold box into the curing room for 10-20 days of initial curing at room temp...

Abstract

The invention provides a method for preparing an artificial landscape stone from regenerative construction wastes. The method is characterized by comprising the following steps of: 1) manufacturing a support of the landscape stone by channel steel or steel angles; 2) brushing a layer of releasing agent on a mould box and putting a processed landscape stone keel into the mould box to be fixed; 3) adding water into a stirring machine, adding construction waste based regenerative fine aggregates, construction waste based regenerative coarse aggregates, construction waste powder, silicate cements, artificial sand and crushed granite into the stirring machine to stir for 3-5 minutes, and pouring the mixture into the mould box; 4) putting the poured mould box into a curing chamber to carry out initial curing at constant temperature for 10-20 days; 5) demoulding the artificial landscape stone which is initially cured; 6) evenly stirring unsaturated resins, accelerants and hardening agents to prepare a binding agent; 7) uniformly smearing the binding agent to a semi-finished product; 8) performing quality inspection; and 9) putting a finished product into a warehouse. The method has the advantages that the construction wastes are comprehensively utilized, so that construction resources are saved, construction cost is reduced, and environment pollution is reduced.

Description

technical field [0001] The invention relates to the field of artificial landscape stone processing, in particular to a method for preparing artificial landscape stone regenerated from construction waste. Background technique [0002] With the acceleration of urban construction and landscaping design, landscape stones are used more and more frequently. Landscape stones are not only beautiful and practical, but also easy to obtain materials, almost everywhere. Landscape stones are widely used and can be seen everywhere in landscape design, such as patios, lawn paths, around swimming pools, railings, villa foundations, gazebos, porches and other buildings that require landscape stones for decoration and beautification. Under the national policy of sustainable development, it is not advisable to take stones from mountains at will. Natural landscape stones are often overweight, which makes construction more difficult and requires more manpower and material resources. [0003] At...
