Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 11968-2006 "Autoclaved Aerated Concrete Blocks", compared with GB/T 11968-2006, except for editorial revisions
The main technical changes of the external change are as follows.
---The block grade is deleted (see 4.3 in the.2006 edition);
---Added product classification, divided into type I and type II, and size deviation and appearance quality requirements (see 4.1.1, 6.1 and 6.2);
---Deleted A7.5, A10.0 intensity level and B08 dry density level (see 4.2 in the.2006 edition);
--- Modified the classification based on compressive strength and dry density to classification based on compressive strength (see 6.3, 6.2, 6.3 and 6.4 of the.2006 edition);
--- Modified the regulations on sampling batches for factory inspection (see 8.2.2.1, 8.2.2.1 of the.2006 edition).
This standard was proposed by the China Building Materials Federation.
This standard is under the jurisdiction of the National Cement Products Standardization Technical Committee (SAC/TC197).
