preparation example Construction

[0026] In order to better achieve the purpose of the invention, the present invention also provides a method for preparing a non-load-bearing self-insulating block, comprising the following steps:

[0027] Step 1. Take the raw materials according to the ratio of parts by weight, pulverize the aerated concrete construction waste to 3-5mm through a hammer mill, mix with fly ash, stone chips, cement and YT inorganic thermal insulation material, feed the After electronic metering and mixing, it is transported to a strong mixer and mixed with 5-10 parts of water and 0.1-0.12 parts of admixture for mixing. The stirred raw materials are sent to the vibration block forming machine through a belt conveyor and pressed at room temperature. ; Then the polystyrene board is cut into shape with a cutting machine according to the size in the workshop, and filled manually.

[0028] Step 2. After the block is formed, it is placed on the bracket by the falling machine, and transported by forklif...

Abstract

The invention discloses a non-bearing self-thermal insulation block and a preparation method thereof. The self-thermal insulation block comprises the raw materials, by weight, 30-40 parts of coal ash, 10-15 parts of aggregate chips, 10-15 parts of cement, 15-20 parts of aerated concrete construction waste and 8-10 parts of YT inorganic active thermal insulation materials. The non-bearing self-thermal insulation block and the preparation method thereof have the advantages that the waste is recycled, resources are saved, environmental protection is facilitated, the self weight of the self-thermal insulation block is lowered, the main components are crushed construction waste aerated concrete block broken materials which replace part of aerated concrete aggregate chips, and the self weight is lowered. Compared with similar products, about 15 kg of self weight can be lowered per cube, and the thermal insulation effect is improved by 10% when the YT inorganic active thermal insulation materials are added.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a non-load-bearing self-insulating block and a preparation method thereof. Background technique [0002] At present, composite blocks produced by materials such as fly ash, slag, and coal gangue in our country have been widely used in construction projects. That is to say, it digests a large amount of land-occupied waste and replaces clay bricks. It has a very prominent effect on two-way land saving, energy saving, and material saving. However, some walls still need external wall insulation to meet the national energy-saving requirements of 50% for public buildings and 65% for residential buildings. During the production, use, and demolition of blocks, a large amount of construction waste will still be generated, which will pollute the environment. Taking fly ash aerated concrete block as an example, its main components are fly ash, cement, gypsum, a small amount of ...
