Abstract

The invention discloses a thermal insulation mortar for building external walls. The thermal insulation mortar consists of sulfate aluminium cement, papermaking sewage sludge ash, polystyrene granules, glazed hollow beads, cellulose ether, an air-entraining agent, a polycarboxylate superplasticizer, alkali-resistant glass fibers and water, and further discloses a preparation method of the thermal insulation mortar. As paper mill sludge ash replaces part of cement, the compactness and the water resistance are very good, the thermal insulation mortar is stable in physical property, free of cracks, ageing-resistant, long in service life and excellent in thermal insulation performance. Not only is harmless utilization of paper mill sludge ash realized to protect the environment, but also resources are saved, waste is changed into valuable, the consumption of cement is reduced, the cost is lowered, and favorable economic and social benefits are achieved. The preparation method is simple, can be completed according to the conventional technology 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 building exterior wall thermal insulation mortar 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. In Europe, t...
