Surprisingly, gypsum still has this function. The original gypsum played a regulating role in the production of aerated brick. It is a commonly used cementing material. Gypsum not only acts as a regulator of gas process, but also can improve the strength, shrinkage and frost resistance of products by participating in hydrothermal synthesis reaction. Gypsum in the production of aerated brick mainly has the following aspects:

　　首先，要參與鋁粉的氣體反應(yīng)，當(dāng)有石膏存在時(shí)，與鋁粉在水中形成氫氧化鋁反應(yīng)形成硫酸鈣鋁酸鹽。因此,在一些加氣磚(如水泥-礦渣砂、水泥砂),當(dāng)石膏在水泥消耗太多的鋁粉的反應(yīng),快速設(shè)置可能會(huì)由于缺乏抑制chalate水泥石膏,石膏應(yīng)補(bǔ)充道。

　　Firstly, it is necessary to participate in the gas reaction of aluminium powder. When gypsum exists, it reacts with aluminium powder to form aluminium hydroxide in water to form calcium aluminate sulfate. Therefore, in some aerated bricks (such as cement-slag sand, cement sand), when gypsum consumes too much aluminium powder in cement, the rapid setting may be due to the lack of inhibition of Chalate cement gypsum, gypsum should be added.

　　其次，抑制石灰的消化，延長(zhǎng)其消化時(shí)間，降低其終消化溫度。

　　Secondly, it restrains the digestion of lime, prolongs its digestion time and lowers its final digestion temperature.

　　第三，可以抑制水石榴子石的生成，從而使游離的鋁離子進(jìn)入CSH(I)中，其中部分轉(zhuǎn)化為鋁代托勃莫來(lái)石，而AI2O3本身也能促進(jìn)CSH(I)向托勃莫來(lái)石轉(zhuǎn)化，阻止其向硬硅鈣石轉(zhuǎn)化，因而強(qiáng)度提高，收縮值降低。

　　Thirdly, the formation of hydrogarnet can be inhibited, so that free aluminium ions can enter CSH (I), some of which can be converted into aluminium-substituted tobermorite, while AI2O3 itself can also promote the transformation of CSH (I) to tobermorite and prevent its transformation to anhydrite, thus increasing its strength and decreasing its shrinkage value.

　　第四，提高坯體及制品的強(qiáng)度，改善收縮等性能。濟(jì)南石膏粉在靜停過(guò)程中的坯體內(nèi)參與生成水化硫鋁酸鈣和C-S-H凝膠，使坯體強(qiáng)度提高。增強(qiáng)了坯體適應(yīng)蒸壓時(shí)溫差應(yīng)力和濕差應(yīng)力的能力。在蒸壓過(guò)程中，石膏可以促進(jìn)水熱反應(yīng)的進(jìn)行，使CSH(I)向托勃莫來(lái)石轉(zhuǎn)化。

　　Fourthly, the strength and shrinkage of green bodies and products should be improved. The gypsum participates in the formation of hydrated calcium sulphoaluminate and C-S-H gel during the static shutdown process, so as to increase the strength of the green body. It enhances the ability of green body to adapt to temperature and humidity differential stresses during autoclaving. In the autoclave process, gypsum can promote hydrothermal reaction and make CSH (I) transform to tobermorite.
