Abstract
A thermal-insulation anti-cracking mortar is prepared from following raw materials, by weight, 20-30 parts of fly ash, 30-40 parts of carbide slag, 2-4 parts of salicylic acid, 7-10 parts of graphite powder, 10-14 parts of talcum powder, 2-3 parts of borax, 2-3 parts of wood fibers, 3-5 parts of polypropylene fiber, 2-3 parts of calcium formate, a proper amount of water, 20-25 parts of additives, 1-2 parts of a water repellent agent, 180-200 parts of cement and 300-330 parts of expanded perlite . The mortar is good in workability, flowability and water-retaining property, is easy to construct, is good in anti-sagging performance, is strong in thermal insulation, can be firmly adhered with wall body, is strong in anti-pressing property and tensile property and is good in anti-cracking performance due to the wood fibers and the polypropylene fibers. With the additives, the mortar is enhanced in anti-pressing and anti-folding strength and is improved in workability, the anti-sagging performance, thixotropism and an anti-settling performance.
Description
Technical field [0001] The invention belongs to the field of building materials, and particularly relates to a thermal insulation and anti-crack mortar and a preparation method thereof. Background technique [0002] Mortar is a common material used in construction and is an essential material in construction. According to the performance classification, there are many kinds of mortar, including combined mortar, caulking mortar, thermal insulation mortar, etc.; according to the purpose, it is divided into masonry mortar, plastering mortar (including decorative mortar, waterproof mortar), bonding mortar, etc. [0003] At present, the performance and quality of mortar are different, which affects the use. Specifically, the factors that affect the performance of the mortar include the workability, fluidity, water retention of the fresh mortar, and the strength of the hardened mortar. It is necessary to study new mortars with excellent workability and processability, anti-sagging prop...
