Abstract

The invention discloses polymer alkali-resisting mortar and a production method thereof. The polymer alkali-resisting mortar is prepared from the following components in parts by mass: 250-550 parts of cement, 250-650 parts of alkali-resisting fine aggregate, 20-40 parts of a compounding alkali-resisting compacting agent, 30-50 parts of 1250-mesh ground calcium powder, 10-20 parts of a saponification-resisting polymer, 2-6 parts of a macromolecule polymer, 3-7 parts of a water reducing agent, 1-5 parts of an early strength agent and 1-3 parts of a thixotropic agent. Compared with similar products and the prior art, the polymer alkali-resisting mortar disclosed by the invention is good in alkali resistance, good in construction property, high in base layer cohering force, and free from hollowing and cracking.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a polymer alkali-resistant mortar and a preparation method thereof. Background technique [0002] Ordinary alkali-resistant mortar has the following problems: 1. Low impermeability level, which leads to a discount in its alkali resistance; 2. Poor adhesion to the base layer, which is easy to cause hollowing or even the alkali-resistant mortar layer to fall off; 3. Low self-cohesion, Hanging phenomenon is easy to occur during construction, and the construction performance is not good; 4. Poor water retention, easy to shrink and crack. Contents of the invention [0003] In order to solve the problems of low impermeability level, poor alkali resistance, poor construction performance, low adhesion with the base layer, and prone to hollowing and cracking of similar products. The invention provides a polymer alkali-resistant mortar and a preparation method thereof. [0004...
