Embodiment Construction

[0051] Below in conjunction with embodiment the present invention will be further described:

[0052] 1. The ingredients of construction waste light through-hole ceramsite are composed of the following components by weight percentage: construction waste 24%, high-viscosity attapulgite clay 18%, bentonite 10%, powdery attapulgite foaming agent 8%, active Clay waste 6%, hollow microspheres 4%, expanded perlite 1%, expanded vermiculite 1%, light calcium carbonate 3%, ferrous sulfate 0%, quicklime 3% and water 22%.

[0053] 2. The production method of construction waste light through-hole ceramsite: (1) input the ingredients of construction waste light through-hole ceramsite into the running mixing mixer, and stir and mix it into a mixture of construction waste light through-hole ceramsite; (2) Transport the mixture of construction waste light through-hole ceramsite to the extrusion granulator, and extrude and granulate it into semi-finished construction waste light through-hole c...

Abstract

The invention discloses light through-hole ceramsite containing construction waste. The technical scheme of the light through-hole ceramsite is characterized in that the light through-hole ceramsite containing the construction waste comprises components of the construction waste, high-viscosity attapulgite clay, bentonite, a powdery attapulgite foaming agent, activated clay waste residues, hollow microspheres, expanded perlite, expanded vermiculite, light calcium carbonate, ferrous sulfate and quick lime. The components of the light through-hole ceramsite containing the construction waste are stirred, mixed, and subjected to extruding granulation, drying, roasting, thermal insulation, screening and sealed packaging, and the light through-hole ceramsite containing the construction waste is obtained. The light through-hole ceramsite containing the construction waste has the characteristics of large specific surface area, low stacking density, high water absorption rate, excellent air permeability, attractive appearance modeling, no abnormal odor and good light strength and integrates micropores and macropores; when the light through-hole ceramsite is used for cultivating or planting various seedlings, flowers, plants and vegetables, roots of the plants can absorb water or nutritional ingredients of liquid fertilizer from the light through-hole ceramsite containing the construction waste, so that good growth and development and high survival rate of the plants are guaranteed, and the light through-hole ceramsite is suitable for preparing soilless culture substrates and nutrient soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a lightweight through-hole ceramsite for construction waste. Background technique [0002] The soil used for cultivating or planting various seedlings, flowers and vegetables is mostly made of nearby soil, and then mixed with some plant ash or peat soil. The moisture content of these soils is 12-20%, and contains a large amount of harmful bacteria. [0003] When using these soils to cultivate or plant various seedlings, flowers and vegetables, it is difficult to control the amount of water in the later stage. After water replenishment, the soil moisture content exceeds 30%, and the moisture content in the soil is relatively high, and the soil will be semi-fluid. If the soil is not replenished in time, the soil will appear compacted and hard, which will directly affect the normal growth of plants. [0004] With the continuous improvement of the quality requirements of greening projects, materials su...
