Exterior decoration mortar and productive construction technology thereof

Abstract

The invention discloses an exterior wall decoration mortar which comprises white cement, fly ash and granulating slag. Each constituent comprises the following components by weight per 1,000 portion of mortar: 110-150 of fly ash, 185-285 of white cement, 220-290 of granulating slag for Phi 0.1-0.7 mm, 190-240 for Phi 0.2-0.6 mm, 100-160 for Phi 0.4-1.0 mm, 50-100 for Phi 1.2-1.6 mm. The invention adopts the homogeneous materials of decoration mortar and base layer of the wall surface, both mortars have identical dry shrinkage rate and physical and chemical index; the decoration mortar has good compactness once being finished according to the requirement of construction characteristics, thus the water proof performance is good; adequate redispersible emulsion powder allowing for anti-cracking requirement is blended when the mortar is prepared to lead the mortar to have a certain flexibility to overcome the disadvantage that the anti-cracking performance is not satisfactory when the mortar is resisting the cement material with high rigidity, thus the weatherability of the mortar is greatly enhanced. The test result indicates that the invention provides a mortar that can be fadeless and can not be damaged for 50 years.

Description

technical field [0001] The invention relates to the construction field, in particular, the invention relates to an exterior wall decoration mortar and its production and construction technology. Background technique [0002] The decoration project (final decoration layer) of the exterior wall of the new house currently being built or the old house being repaired is basically based on two types of materials, one is ceramic veneer wall tiles, and the other is exterior wall paint. The two types of materials have many advantages, but they also have defects. The most important of these defects is that the weather resistance is very poor. Generally, it needs to be repaired within ten years. If the construction quality is poor or the drainage system is faulty, the shortest decorative layer is 2- Damage phenomena such as peeling and discoloration will appear within 3 years. This type of damage occurs and the house must be repaired, and the repair costs are huge. [0003] The prese...

[0002] The decoration project (final decoration layer) of the exterior wall of the new house currently being built or the old house being repaired is basically based on two types of materials, one is ceramic veneer wall tiles, and the other is exterior wall paint. The two types of materials have many advantages, but they also have defects. The most important of these defects is that the weather resistance is very poor. Generally, it needs to be repaired within ten years. If the construction quality is poor or the drainage system is faulty, the shortest decorative layer is 2- Damage phenomena such as peeling and discoloration will occur within 3 years

When such damage occurs, the house must be repaired, and the maintenance cost is huge.
