加气混凝土的气孔率主要取决于铝粉的加入量，从而也就直接的决定了加气混凝土的体积密度，所以铝粉是加气混凝土墙板中必不可少的配料。加气混凝土的强度同样服从于孔隙率理论，气孔率越大，体积密度越小，强也就越低。如果保持气孔率不变（体积密度也相应地不变），改变气孔的大小，也可以改变加气混凝土的强度。

　　The porosity of aerated concrete mainly depends on the amount of aluminum powder, which directly determines the volume density of aerated concrete, so aluminum powder is an essential ingredient in aerated concrete wall panels. The strength of aerated concrete is also subordinate to the theory of porosity, the greater the porosity, the smaller the volume density, and the lower the strength. If the porosity is kept constant (the volume density is also invariable), the strength of aerated concrete can be changed by changing the size of the gas hole.

　　由于加气混凝土墙板的重要作用，越来越多的高层建筑开始使用加气混凝土墙板作为墙体材料，这也就意味着加气混凝土墙板制品的安全性越来越重要，对于建筑来说，建筑所用的加气砖相当于建筑的根基，只有安全牢固的根基，才得以确保建筑的安全可靠，屹立不倒，而对于加气混凝土墙板来说，影响加气混凝土墙板制品安全的一个重要因素就是气孔率，其直接影响着加气混凝土墙板制品的安全和个性。加气混凝土墙板制品是由无数个气孔和气孔壁组成的，因此对加气混凝土墙板来说，其强度受气孔的结构及形状的影响较大，对于成品的加气混凝土墙板制品是否合格有着决定性的影响。如果保持气孔率不变，改变气孔的大小，也可以改变加气混凝土的强度。在工艺条件许可时，尽量减小气孔的尺寸，将可以提高加气混凝土的强度。如果将气孔与孔间壁中的毛细孔、胶凝孔一起计算孔隙率，加气混凝土的总孔隙率可达70%.有的研究者认为，如果保持孔隙率不变，减少气孔含量，增大毛细孔含量，同样可以提高加气混凝土的强度。

　　Because of the important role of aerated concrete wall, more and more high-rise buildings began to use aerated concrete wall as wall material, which means more safety of aerated concrete wall products more important, for the construction, the foundation of aerated brick used in the building the equivalent of building safety, only solid foundation, to ensure that the building safe and reliable, standing for the aerated concrete wall, an important factor influencing the aerated concrete wall products safety is porosity, it directly affects the aerated concrete wall plate product safety and personality. Aerated concrete wall panel products are made up of numerous stomata and stomatal walls. Therefore, the strength of aerated concrete wall panels is greatly influenced by the structure and shape of air holes, which has a decisive impact on whether the finished products of aerated concrete wall panels are qualified. If the porosity is kept constant and the size of the air hole is changed, the strength of the aerated concrete can be changed. When the process conditions are permitted, the size of the gas hole is minimized, and the strength of the aerated concrete can be improved. If the hole and the hole in the wall of the pores, cementing hole to calculate porosity, total porosity of aerated concrete is 70%. some researchers believe that if maintaining porosity unchanged, reduce porosity content, increase pore content, can also increase the strength of aerated concrete.

　　总而言之，加气混凝土墙板气孔的缝隙率对于成品砖的产品质量有着举足轻重的影响，对于任何产品任何设备只有保证了其成品质量、产品安全，才能让人放心使用。而对于加气混凝土墙板来说，由于其都是批量生产，一旦开始出现错误，那么其整条产品线都将产生严重影响，造成严重经济损失，所以在量产前，一定要做好检测，严格管控其气孔缝隙率，从源头防止成品砖质量。在生产过程中要对于成品砖进行不定期抽检，发现质量问题及时停止施工，纠正错误，使成品砖质量影响减少到最小。

　　To sum up, the porosity rate of aerated concrete wall panels has a decisive impact on the quality of finished bricks. For any product and any equipment, it can guarantee people's ease of use only by ensuring the finished product quality and product safety. As for the aerated concrete wall, because it is mass production, once appear mistake, then the entire line will have a serious impact, causing serious economic losses, so we must do a good job in pre production, detection, strict control of the air gap rate, from the source to prevent the quality of finished bricks. In the production process, we must make random sampling for finished bricks, find quality problems, stop construction in time, correct errors, and minimize the impact of finished brick quality.
