Self-leveling waterproof mortar of imitated stone facing and construction process of waterproof mortar

Abstract

The invention discloses a self-leveling waterproof mortar of an imitated stone facing and a construction process of the waterproof mortar. The self-leveling cement mortar is composed of the following components in parts by weight: 250-300 parts of cement, 50-80 parts of ground calcium carbonate, 900-1000 parts of natural color sand, 2-8 parts of cellulose ether, 3-8 parts of wood fibers, 1-3 parts of PP (Poly Propene) fibers, 18-25 parts of latex powder and 2-8 parts of special natural rock slices for really stone paint; a water-to-material ratio is 4.2L-4.5l / 25kg. The construction process of the waterproof mortar comprises the steps of base surface treatment, interface treatment, material stirring and material construction. The self-leveling waterproof mortar is a dry-blending type powdery material composed of a plurality of active ingredients, and can be mixed with water in field to be use. The self-leveling waterproof mortar is slightly spread by using a scraper knife and then a high-level base surface can be obtained. The self-leveling waterproof mortar is hardened quickly, and after 4-8 hours, people can walk on the hardened mortar or subsequent work can be carried out on the hardened mortar; the self-leveling waterproof mortar is quick, simple and convenient in construction and can be applied to industrial factory buildings, workshops, commercial stores and the like.

Description

technical field [0001] The invention specifically relates to a waterproof mortar for self-leveling imitation stone veneer and its construction technology. Background technique [0002] Self-leveling material is a kind of self-leveling material for the ground developed in recent years based on inorganic gelling materials. Foreign self-leveling materials are divided into two categories: gypsum series self-leveling materials and cement series self-leveling materials based on cement. The products are all sold in bags, and you only need to add water and mix them on site according to the regulations when using them. However, some products do not add fine aggregates, so they need to be added on site. [0003] The biggest feature of self-leveling materials is that they can finely level the ground in a large area in a short period of time, which has brought great help to the application and quality of materials in some projects. Self-leveling materials are probably the most complex...

Problems solved by technology

Second, if it is used in a large area in domestic construction projects at present, the cost is relatively high, and it is difficult for users to accept

[0008] (1) The early strength is low. Since the cement-based self-leveling mortar generally uses ordinary Portland cement as the main cementing material, ultra-fine sand and high water-cement ratio are used, the early strength of the mortar is seriously insufficient, which directly affects the construction process. and the time when the project was put into use

[0009] (2) The flatness of the mortar surface is not enough. Due to the imperfect mortar formula, it is easy to produce surface sanding, peeling, hollowing, etc., which not only affects the appearance, but also directly endangers the quality of self-leveling mortar

[0010] (3) Insufficient wear resistance, self-leveling mortar is mainly suitable for large supermarkets, shopping malls, parking lots, factory workshops, warehouses and other floors, which require high wear resistance

[0011] (4) After the mortar is hardened, it is easy to shrink and crack

This leads to cracking after the mortar hardens
