The invention relates to architectural decoration
mortar and an application thereof. The architectural decoration
mortar contains the ingredients in parts by weight: 24-28 parts of
silicate cement, 40-65 parts of high-
alumina cement, 7-15 parts of plaster, 200-240 parts of
quartz sand with the particle size of 40 to 70 meshes, 440-475 parts of
quartz sand with the particle size of 70 to 140 meshes, 0.5-2.2 parts of wood fibers and 5-33 parts of
metal alloy pigment. According to the architectural decoration
mortar, the
silicate cement, the high-
alumina cement and the plaster serve as a gelatinization
system, the
silicate cement and the high-
alumina cement can rapidly produce
ettringite with the plaster in case of encountering water, the
ettringite wraps the surface of cement clinker so as to form a protective film, thus, the production and further hydration of
calcium hydroxide are avoided, then, the production of alkalis is reduced, and the problem of efforescence is solved. The high-alumina cement and the
silicate cement jointly produce gehlenite
hydrate during hydration; and by adopting the
quartz sand of size distribution and the wood fibers, the
mechanical strength and durability of the architectural decoration mortar are further guaranteed. The architectural decoration mortar can reflect 10% to 20% of
infrared radiation in
sunlight, thereby playing roles in insulating heat and saving energy.
