Aerated concrete blocks have been widely used in non-load-bearing walls and load-bearing walls. The load-bearing hollow block bricks produced by professional technology are the leading products of load-bearing wall materials.
According to different needs, it can produce different grades of compressive strength, such as 1.5 MPa-35 MPa, load-bearing wall above 5.0MPa and non-load-bearing wall of frame structure below 5.0MPa. The strength of load-bearing block brick can be completely higher than that of clay sintered brick.
1, non-load-bearing wall aerated concrete block product age should be greater than 28d, the strength should meet the design strength of the product.
2, aerated concrete block according to the strength and dry density classification:
(1) strength grades are: A 1.0, A2.0, A2.5, A3.5, A5.0, A7.5, A 10.0, * * *.
(2) Dry density grades: B3.0, B4.0, B5.0, B6.0, B7.0, B8.0 and * * *.
3, aerated concrete block in the process of transportation, stacking, it is forbidden to get wet in the rain, masonry process shall not be mixed with other different grades of masonry.

Article 49 of the "Building Law": "For renovation projects involving changes in the main building and load-bearing structure, the construction unit shall entrust the original design unit or a qualified design unit to propose a design scheme before construction; Without a design plan, construction is not allowed. "
Article 70: "Whoever, in violation of the provisions of this Law, carries out decoration works involving changes in the main building or load-bearing structure without authorization shall be ordered to make corrections and be fined; If losses are caused, it shall be liable for compensation; If it constitutes a crime, criminal responsibility shall be investigated according to law. "
Article 5 of the Measures for the Administration of Residential Interior Decoration: "In residential interior decoration activities, it is forbidden to change the building subject and load-bearing structure without the consent of the original design unit or the design unit with corresponding qualification grade.
