Embodiment Construction

[0021] refer to figure 1 , The new light aggregate concrete block of the present invention includes a small hollow block 2 of light aggregate concrete with a cavity 1, and the feature is that a thermal insulation board 3 is inserted in the cavity. The volume ratio of each component of the above concrete formula is as follows: cement: fine aggregate: coarse aggregate: water = 5-15%: 20-50%: 20-50%: 5-15%.

[0022] In order to facilitate waste utilization and reduce production costs, the fine aggregate can be one or more of materials such as sand and bottom ash; the coarse aggregate can be stone, coal gangue, ceramsite, etc. One or several raw materials in the material.

[0023] In order to prolong the heat flow transmission line and enhance the heat preservation effect, the cavity of the hollow block has multiple rows of holes (usually elongated square holes), and two adjacent rows of holes are arranged in a staggered manner.

[0024] The implementation steps of the present i...

Abstract

The invention relates to a novel light aggregate concrete building block and a using method thereof. The building block comprises a light aggregate concrete small-sized cavity block provided with a cavity bore. The building block is characterized in that: an insulation board is inserted into the cavity bore. The novel light aggregate concrete building block has the advantages of high strength, high thermal insulation performance, capability of consuming local waste, convenient transportation and masonry, and fewer common faults of wall quality, is the novel wall building block, is suitable for large-scale popularization and application, and has obvious economic benefit.

Description

technical field [0001] The invention relates to a novel lightweight aggregate concrete block and a method for using the same, belonging to the technical field of building materials. Background technique [0002] At present, my country's building energy consumption has accounted for 27% of the total energy consumption of the whole society, becoming a major energy consumer. Wall energy consumption accounts for about 60% of building energy consumption. The design service life of buildings in our country is 50 to 100 years, and buildings will consume a lot of energy during the long service period. Therefore, the research, development and popularization of wall blocks with good thermal insulation and heat insulation properties, high compressive strength, and a large number of industrial waste (not using cultivated clay) have become one of the focuses of the reform of new wall materials in my country. [0003] The self-insulation wall is favored by the construction industry beca...
