Anti-dry-crack type alkali-activated concrete inner wall surface layer and construction method thereof

Abstract

The invention discloses an anti-dry-crack type alkali-activated concrete inner wall surface layer and a construction method thereof. The anti-dry-crack type alkali-activated concrete inner wall surface layer is mainly prepared from cement, coarse sand, gravel, water, alkali, anti-dry-crack fibers and additives. According to the invention, the Danstrength silk fiber, the polypropylene fiber, the polyester fiber and the wood pulp fiber are added into the concrete, so that the crack resistance of the concrete is improved, the phenomenon of dry crack of the concrete is prevented, and meanwhile, the quartz powder can improve the strength and compactness of the concrete and improve the freezing resistance of the concrete; the connection stability of the concrete and the surface of the inner wall can be improved by wetting the inner wall, water spraying maintenance can prevent the surface of the concrete from losing water and cracking, and the problems that an existing concrete inner wall surface layer and a construction method thereof are prone to cracking after construction, the surface of the inner wall cracks, and the attractiveness of the building inner wall is affected are solved. And troubles are brought to subsequent decoration.

Description

Technical field: [0001] The invention relates to the technical field of concrete, in particular to a surface layer of an anti-dry cracking type alkali-activated concrete inner wall and a construction method thereof. Background technique: [0002] The concrete interior wall is used to protect the wall and improve the indoor environment regulation. Because of its great decorative effect, it is widely used in interior decoration. However, because it cannot meet the long-term surface maintenance requirements of concrete, waterproof materials are generally added to ordinary concrete, thereby To achieve the effect of waterproof and anti-cracking; Chinese patent 201510648816X discloses an alkali-activated phosphorus slag micro-powder lightweight foam concrete insulation board and its preparation method. The mass percentage of each raw material is: phosphorus slag micro-powder 35-39%, alkaline activator 6-10%, coagulation regulator 7-12%, modifier 9-15%, fiber 0.4-0.8%, foaming agen...
