Air-entrained block waterproof plastering mortar

1. Product introduction:
Aerated block waterproof plastering mortar is a dry powder material made of high-strength and high-modulus fibers, organic compounds, inorganic materials and admixtures, processed by special equipment. The bag is opened and water is added on site. Ready 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 is used , there will be some toughness and water seepage, such as poor adhesion, hollowing and cracking of the plaster layer, etc.; in order to solve the above problems, give full play to the high and new technologies of modern construction chemical materials, combined with the actual construction characteristics of Chinese construction projects, and focus on traditional plastering When mortar is used in lightweight block construction, the water in the mortar is easily taken away by the blocks and cannot be fully hydrated, resulting in loss of strength and difficulty in ensuring project quality. It is a carefully developed functional building material.

2. 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 anti-penetration and frost resistance of mortar and hardened body. , Wear resistance, thereby inhibiting the generation and development of micro-cracks in the plaster mortar, thus 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 it can also meet the requirements of firmness, stability and durability of the wall plaster layer. This not only facilitates construction, but also overcomes the disadvantages of traditional construction methods that are difficult to control the wall from cracking, hollowing, and falling off due to dry-wet cycles. It also ensures and improves 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 and increase the strength of the cement. It is suitable for use in dry climate conditions. This water retention is particularly useful in mortars constructed under or on highly absorbent substrates.
5. It has high lubricity, is easy to construct, has 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. Its tensile strength, bonding strength, toughness, impact resistance, frost resistance, wear resistance and other properties have been significantly improved, greatly improving the wall resistance. Crack, impermeability and strain resistance.
7. It has the characteristics of convenient transportation, no environmental pollution, reliable quality, simple construction, environmental protection, and project cost saving.

3. Scope of application:
1. Used for plastering of internal and external walls of various new lightweight wall materials with strong water absorption (aerated concrete blocks, lime sand bricks, clay bricks) mortar project.
2. Mortar projects used 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 5-7kg.
Powder: water = 4:1

5. Packaging and storage:
50 kg, packed in a lined film bag, the unopened bag is valid for 6 months in a dry environment moon. </p
