Abstract

The invention discloses a thermal insulation mortar containing papermaking sludge ash; the thermal insulation mortar is composed of sulfoaluminate cement, the papermaking sludge ash, polyphenyl particles, vitrified micro-beads, cellulose ether, an air-entraining agent, a polycarboxylic acid water reducing agent, alkali-resistant glass fiber and water. The invention also provides a preparation method of the thermal insulation mortar. With use of the papermaking sludge ash instead of partial cement, the thermal insulation mortar has the advantages of good compactness and waterproof performance, stable product physical properties, no cracking, aging resistance, long service life and good thermal insulation performance, not only realizes the papermaking sludge harmless utilization and protects the environment, but also can save resources, turns waste into wealth, reduces the amount of the cement, reduces the cost, and has good economic and social benefits. The preparation method is simple, can be completed according to a conventional technology process, and is low in production cost.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal insulation mortar containing papermaking sludge ash and a preparation method thereof. Background technique [0002] Insulation mortar mainly uses cement as the cementitious material, lightweight materials as the aggregate, mixed with modified admixtures of specific components, and a certain amount of admixture is introduced, and after being stirred by a mixer, it is used to build external wall insulation Base mortar in the system. In recent years, some new materials are often used to replace traditional cementitious materials and aggregates, mainly including finely ground granular blast furnace slag, fly ash, silica fume, glass, rubber and milled cable waste, etc. [0003] With the development of the economy, the amount of paper used is increasing, and the sludge produced by the paper industry every year has brought serious pollution to the environment.
