Code requirements for masonry structure of aerated block wall

1. Material requirements: A. Aerated blocks shall meet the requirements of national standards and have certain compressive strength and frost resistance. B. Cement and sand materials that meet the requirements shall be used for mortar to ensure the bonding strength and durability of mortar.

2. substrate treatment: a. the substrate should be firm, flat and clean. If there are irregularities, trim them. B. Brush a layer of cement mortar with a concentration not higher than 1:3 on the surface of the base to enhance the bonding with the aerated block.

3. Treatment of chimney, column and other components: a. Chimneys, columns and other components should be made of brick masonry, the dimensions should meet the design requirements, and the verticality and flatness should meet the specification requirements. B the joint of chimney, column and aerated block wall should be strengthened to ensure the stability and sealing of the structure.

4. Masonry process requirements: a. The aerated block shall be brushed with a thin layer of cement mortar, and then laid according to the design requirements. B. The aerated block wall shall adopt dry masonry or semi-dry masonry technology, and the verticality and levelness of the wall shall meet the specification requirements. C. The junction of aerated block wall should be vertical and straight, with full mortar and no empty drum and gap. D the hole of the aerated block wall should be reinforced to ensure the stability of the hole.

5. Masonry quality control: a. Aerated block wall should be fully wet cured to ensure the bonding strength of mortar. B. Check the verticality, levelness and flatness of the wall, which shall not exceed the allowable range of the specification. C. quality problems should be rectified and repaired in time.

The above are some basic contents of the Code for Construction of Aerated Block Wall Masonry, and the specific requirements need to be adjusted and supplemented according to the actual situation of the region and the project. During the construction, the construction unit shall operate in strict accordance with the requirements of relevant specifications to ensure the construction quality and safety.
