Problems solved by technology

However, since the thermal insulation performance of concrete hollow blocks is not as good as that of solid clay bricks, the 190 thick block wall is only equivalent to the thermal insulation effect of 150 thick clay solid bricks, so many problems have been encountered in the process of popularization and application.

Abstract

The invention relates to the technical field of preparing hollow insulation building blocks with environmental light aggregate concrete, in particular to light aggregate concrete building blocks prepared with industrial waste materials such as polystyrene granules, slag, pulverized fuel ash, etc., which can well make use of local resources and lead industrial waste materials such as slag, pulverized fuel ash, etc. to be profitable. The volume density of the environmental insulation building blocks is 700 - 750kg / m<3> and the compressive strength of the building blocks reaches to 1.5MPa to 2.5MPa or more; moisture content is 1.7 percent and water absorption rate is 9.3 percent; relative moisture content is 28.8 percent and the resistance of heat transfer of a wall body with the thickness of 190mm is 0.53m<2>.K / W. The dynamic, physical and thermal properties are all relatively good under the condition of guaranteeing light weight.

Description

technical field [0001] The invention relates to the technical field of producing environment-friendly and energy-saving light aggregate concrete hollow thermal insulation blocks, in particular to producing light aggregate concrete blocks by utilizing industrial waste such as polyphenylene particles, slag and fly ash. Background technique: [0002] At present, new building materials are widely promoted and applied in the construction industry. It has been proved in practice that concrete blocks are ideal wall materials to replace clay bricks, because the production process of concrete hollow blocks is not only energy-saving, land-saving, and beneficial Environmental protection, in line with the requirements of green wall materials, and the construction speed is fast, one standard block is equivalent to ten clay bricks, the density is lighter than solid clay bricks, reducing the foundation cost and the amount of masonry mortar, the wall is thinner, an...
