Abstract

The present invention discloses a production method of ceramsite lightweight concrete battens (wallboards) by using a non-autoclaved technology. The ceramsite concrete includes the following components: a cementitious material, fine aggregate, coarse aggregate, a water-reducing agent, a foaming agent and water, wherein the bulk density of the concrete is 1000-1400 kg/m3, the amount of the cementitious material is 300-400 kg/m3, the fine aggregate is a mixture of one or more of river sand, artificial sand and ceramic sand with a amount of 300-600 kg/m3, the coarse aggregate is artificial lightweight ceramsite with a amount of 500-700 L/m3, the water-binder ratio is 0.30-0.40, the usage amount of the foaming agent after mechanical foaming is 200-280 L/m3, and the mixing amount of the water-reducing agent (solid content) is 0.1-1.2% of the weight of the cementitious material. The invention also discloses the preparation method for the ceramsite lightweight concrete battens (wallboards). The method uses the non-autoclaved technology for production, and at the same time can promote the durability and other performances of the ceramsite lightweight concrete battens (wallboards) under the premise of realization of ceramsite lightweight concrete battens (wallboards) non-autoclaved production.

Description

technical field [0001] The invention relates to a ceramsite lightweight concrete strip (wall panel) produced by an autoclave-free technology, and also relates to a preparation method of the ceramsite lightweight concrete strip (wall panel), which belongs to the field of new environment-friendly building materials. Background technique [0002] my country is a country with a large population. Although resources are abundant, per capita resources are relatively insufficient. Our country is not only short of energy, shortage of arable land, but also serious environmental pollution and ecological damage. Therefore, it is of far-reaching historical significance to vigorously develop new wall materials that are energy-saving, soil-saving, environmentally friendly and improve building functions in our country. It is a major measure to achieve sustainable development, and it is also a great cause for the benefit of future generations. [0003] At this stage, as one of the new wall ...
