Air-entrained block waterproof plastering mortar

1. Product introduction:

Air-entrained block waterproof plastering mortar is a dry powder material made of high-strength and high-modulus fibers, organic compounds, inorganic materials and additives, processed by special equipment. Open the bag and add water to use.

The application technology and supporting materials of air-entrained blocks are one of the major issues in the current promotion of aerated concrete, a new building material. Due to the characteristics of the “porous” pore structure of air-entrained blocks, if traditional Cement mortar plastering will cause some toughness and water seepage, such as poor adhesion, hollowing and cracking of the plaster layer, etc. In order to solve the above problems, we should give full play to the high and new technologies of modern construction chemical materials and combine them with the actual construction characteristics of Chinese construction projects. This is a functional building material carefully developed for the purpose that when traditional plastering mortar is used for lightweight block construction, the water in the mortar is easily snatched away by the blocks and cannot be fully hydrated, resulting in loss of strength and difficulty in ensuring project quality.

II. Product characteristics:

1. It has the characteristics of low plastic shrinkage and dry shrinkage, which can reduce the early plastic shrinkage cracks of mortar and improve the permeability and resistance of mortar and hardened body. It has good frost resistance and wear resistance, thereby inhibiting the generation and development of micro-cracks in the plaster mortar, thereby playing the roles of waterproofing and crack resistance, shrinkage reduction, toughening, and strengthening.

2. It has excellent bonding performance and adopts dry slurry method for construction. There is no need to water and moisten the masonry before plastering the wall, and the wall plaster layer can also be firm and stable. Durability requirements, thereby not only facilitating construction, but also overcoming the disadvantages of traditional construction methods that are difficult to control the wall from cracking, hollowing, and falling off due to dry-wet cycles, and also ensuring and improving the construction quality of the plastering project.

3. Excellent construction workability. That is to say, the workability is very good, and the mortar will not cause bleeding and segregation, which greatly facilitates the construction operation and can fully protect the wall.

4. It has excellent water retention, and can basically retain the water required for cement hydration in the cement mortar. The good water retention properties allow the cement to be fully hydrated, increasing the strength of the cement, which is suitable for drying. This water retention property is particularly useful for mortars constructed under harsh climate conditions or on highly absorbent substrates.

5. It has high lubricity, is easy to construct, produces less dust on the ground during construction operations, and has a certain water-reducing effect, which can reduce the water consumption of the mortar, which can significantly reduce the dry shrinkage of the mortar.

6. It has mechanical properties with moderate toughness, and its tensile strength, bonding strength, toughness, impact resistance, frost resistance, wear resistance and other properties have been significantly improved and greatly improved. The wall’s ability to resist cracking, seepage and strain.

7. It has the characteristics of convenient transportation, no pollution to the environment, reliable quality, simple construction, environmental protection, and project cost saving.

3. Scope of application:

1. Used in interior and exterior walls of various new lightweight wall materials with strong water absorption (aerated concrete blocks, lime sand bricks, clay bricks) Plastering mortar work.

2. Used in mortar projects for plastering internal and external walls such as clay porous bricks and concrete hollow blocks.

4. Dosage and ratio:

Dosage: The recommended plastering thickness is 3-5mm, and the reference dosage is 5-6kg/m³.

Powder: water = 4:1

V. Packaging and storage:

This product is packed in lined film bags, 50kg/bag, unopened The bag is valid for three months in a dry environment. </p
