Example Embodiment

[0037] Example 1

[0038] Take each component according to the weight shown in Example 1 in Table 1. The production process is as follows: mix ordinary Portland cement, slaked lime, light aggregate, heavy aggregate and G-type compound additives according to the above specific gravity, and stir evenly by mechanical , The natural aeolian sand exterior wall decorative mortar of Example 1 is obtained, which can be packed in paper bags or in bulk.

[0039] Construction method: Take 100 kilograms of natural aeolian sand exterior wall decorative mortar obtained in the above example 1, add 30 kilograms of water to dilute, mechanically or manually stir until the mixture is uniform, and reach a viscosity suitable for mechanical spraying or manual construction. Manually, a decorative mortar layer with an average thickness of approximately 1-3mm is formed on the outer wall surface.

[0040] Perform performance testing according to national standards or industry standards, and the results are sh...

Abstract

The invention discloses a natural aeolian sand mortar for decorating an external wall, which is mixed by the following components in parts by weight: 10-20 of ordinary portland cement, 2-3 of slaked lime, 3-5 of lightweight aggregate, 71-84 of heavy aggregate (aeolian sand), 1.0 of complex additive, wherein the lightweight aggregate is an inorganic vitrified hollow micropore material; the heavy aggregate is the aeolian sand; the preferred fineness of the inorganic vitrified hollow micropore material is 80-100 mesh, the weight content of the aeolian sand with 50-70 mesh preferred fineness is more than 90 percent, and the rest aeolian sand has more than 100-mesh fineness. The invention has the advantages that the mortar has prominent stereo texture, endurance and stability, light weight, saved energy and good crack- resistant and anti-drop properties, and exhibits natural and rich European style customs decoration effect; and the mortar also has good smear workability and simple process, and is suitable for mechanization construction. The construction method is as follows: the mortar is diluted by adding water based on 30-50 percent of the mortar by weight, mechanical agitation or hand stirring is carried out to be evenly mixed to reach a proper viscosity for mechanical spray or hand construction.

Description

technical field [0001] The invention relates to a construction mortar, in particular to an exterior wall decoration mortar and a construction method thereof. Background technique [0002] Now, villas, high-end office buildings, and commercial and residential buildings in many cities have begun to use decorative mortar for surface decoration, and have received good decorative effects. I believe that with the continuous improvement of the quality of life of our people, decorative mortar must be due to its excellent cost performance Become the most important material for decoration. However, most of the existing decorative mortars use quartz sand as the aggregate. For dry powder mortar, on the one hand, the aggregate must be further processed to meet the requirements of use, mainly including screening and drying, and it is required to remove useless particles in the quartz sand. composition, adjust the gradation of quartz sand and reduce the moisture content of quartz sand.
