Self-insulation material of light particle and fiber concrete series

Abstract

The invention relates to a novel material, and belongs to the technical field of building materials. A self-insulation material of light particle and fiber concrete series is disclosed. Sealed waterproof light particles and fine short fibers are mixed into concrete. The invention effectively solves the problem that novel building materials such as aerated concrete and foam concrete are high in water absorption rate, low in strength and easy to crack. Because the self-insulation material of light particle and fiber concrete series contains sealed waterproof light particles and fine short fibers, the material has obvious effects of light weight, high strength, sound insulation, crack resistance, etc., can be prefabricated and cast into various blocks and plates, or cast to mould by shipping in a canned car on site, can be widely used as the materials for self-insulation outer walls, various walls with retaining filling structures and roofing, has a good energy saving effect, conforms to national industrial policies of low carbon and environmental protection, and helps to promote the improvement of energy conservation and environmental protection building materials.

Description

technical field [0001] The invention relates to a new building material, which belongs to the technical field of building materials. Background technique [0002] Air-entrained concrete and foamed concrete are new energy-saving and environmentally friendly building materials that are widely promoted and applied at present. They have the advantages of light weight, good heat preservation, processability and non-combustibility. However, the use is limited to the wall material of the enclosure filling structure in the construction field, and there are still certain defects, such as low strength, cracking, water absorption, etc., and as the water content decreases, it will shrink and deform due to water absorption. High, large shrinkage deformation, often wall cracks, leakage caused by cracks, wall plaster hollowing, cracking and other quality problems. Contents of the invention [0003] In order to improve and accelerate the popularization and application of aerated concrete...

AI Technical Summary

Problems solved by technology

Lightweight, airtight, water-repellent particles replace the air-filled and foamed pores, preventing the intrusion of water from the structure, not only effectively solving the problem of high water absorption of aerated concrete and foamed concrete, but also further reducing the material density and improving The thermal insulation effect is improved; the short fibers of the fine denier make the micro-cracks in the development process blocked by the fiber and consume energy when the concrete shrinks and deforms, making it difficult to further develop, thereby blocking the stress to achieve the effect of crack resistance and enhancing the light weight. Improve the strength and toughness of concrete and improve the bearing capacity of the material
