Colored self-leveling dry-mixed mortar

Abstract

The invention discloses a colored self-leveling dry-mixed mortar. The raw materials for preparing the mortar include the following materials in parts by weight: 42-48 parts of cement, 0-2.5 parts of mineral powder, 0-2.8 parts of fly ash, and 1.5 parts of inorganic pigments ‑2.5 parts, 39‑45 parts of river sand, 5‑10 parts of heavy calcium powder, 0.17‑0.25 parts of water reducer, 0.05‑0.5 parts of defoamer, 0.0025‑0.005 parts of Wenlun glue. The obtained colored self-leveling mortar has good self-leveling properties, suitable mechanical properties and operability in construction. At the same time, in order to meet the aesthetic and functional requirements of the design, different inorganic pigments are used. agent, and developed a color self-leveling mortar, which can maintain uniform color in a complex environment while meeting the requirements of mechanical properties.

Description

technical field

[0001] The invention belongs to the field of building materials, and in particular relates to a colored self-leveling dry-mixed mortar and a preparation method thereof. Background technique

[0002] The traditional ground construction method is to mix ordinary cement mortar, then use manual paving, scraping, plastering, and three times of calendering and other processes must be completed before the final setting of the mortar. This method of multi-layer construction has low production efficiency and a large waste of materials. The most important thing is that its quality is not easy to guarantee. After construction, the ground often has quality problems such as sanding, peeling, hollowing, and cracking. Seriously affect the perception and use effect of houses etc., become the common problem of the quality of common cement mortar ground, and have not obtained effective radical cure. As an important part of the building, the quality of the ground has attracted...
