A ground decoration structure using non-alkali sand anti-separation white material

Abstract

The invention discloses a ground decoration structure using an alkali-free sand white-color-seepage-prevention material. The structure sequentially comprises a bottom surface base layer 1, a white-color-seepage-prevention material layer 2, a protection layer 3, a face layer 4 and a jointing filling material 5 from bottom to top, wherein the white-frost-prevention material layer 2 comprises an alkaline substance consumption layer 2-1 and a white-color-seepage-prevention cement mortar layer 2-2; and the white-color-seepage-prevention cement mortar comprises low-alkali cement, processed good-grading alkali-free sand, fly ash and additives. After the alkali-free sand white-color-seepage-prevention material provided by the invention is used, a caulking material and the white-color-seepage-prevention material layer at the middle layer per se cannot separate out alkaline substances; the white-color-seepage-prevention material layer can prevent moisture from bringing out the alkaline substances through seeping into the bottom surface base layer; the alkaline substances produced during the hydration reaction of the bottom surface base layer can also be effectively reduced; the protection layer forms a sealed layer on the inner surface of the face layer, so that the alkaline substances are prevented from flowing out from pores of the face layer; the occurrence of a white-color-seepage phenomenon is avoided; and a good decoration effect is achieved.

Description

technical field [0001] The invention relates to a ground decoration structure using non-alkali sand anti-whitening material, which belongs to the field of architectural decoration. Background technique [0002] In architectural decoration engineering, it is often seen that white flocculent or powdery substances appear on the surface of the surface layer. This phenomenon is called whitening. This not only affects the surface sensory effect of architectural decorations and the evaluation grade of building sensory quality, but also may affect the quality of decoration projects and even cause quality accidents. Coupled with the fact that the aesthetic requirements of architectural decoration are getting higher and higher, researchers and construction workers are paying more and more attention to the whitening phenomenon. [0003] The whitening of the surface layer surface is mainly due to the soluble alkaline substances in cement, sand, stone and admixtures being dissolved by w...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, the cement mortar layer in the common ground decoration structure, the base layer of the bottom surface and the joint filler contain a large amount of soluble alkaline substances, which may not only dissolve in the stirring water, but also cause whitening within a few days after construction. Whitening occurs within months or even years after construction due to the intrusion of moisture in the air or curing water
