Cement is a hydraulic material and lime paste is a steam hard material. Pneumatic materials shall not be used in humid environment.

石灰砂漿中凝結材料是石灰膏，石灰膏的主要化學成分是氫氧化鈣。石灰砂漿之所以能結硬，是氫氧化鈣吸收了空氣中的二氧化碳，生成碳酸鈣及水，碳酸鈣是有一定強度和硬度的，并且能與砂粘在一起，使石灰砂漿層結硬，由于空氣中二氧化碳含量少，這種化學反應進行緩慢，而且生成的水又要蒸發掉。因此，石灰砂漿結硬是需要很長時間。

The setting material in lime mortar is lime paste, and the main chemical component of lime paste is calcium hydroxide. The reason why lime mortar can harden is that calcium hydroxide absorbs carbon dioxide in the air and generates calcium carbonate and water. Calcium carbonate has certain strength and hardness, and can stick with sand to harden the lime mortar layer. Due to the low content of carbon dioxide in the air, this chemical reaction is slow, and the generated water has to evaporate. Therefore, the hardening of lime mortar takes a long time.

如果在石灰砂漿結硬過程中抹上水泥砂漿，水泥砂漿中由于水泥水化作用快，使水泥砂漿很快就硬化，硬化了的水泥砂漿等于在石灰砂漿面上加了層隔膜，把石灰砂漿層封閉起來，使石灰膏不能吸收空氣中二氧化碳，而且生成的水分也無法蒸發，這樣石灰砂漿始終不能結硬，也不能與物面很好地粘結，兩者之間的粘結力很小。抹上了水泥砂漿又增加了抹灰層自重，往往抹灰層自重超過粘結力，水泥砂漿抹灰層連同石灰砂漿抹灰層會一起撣落下來。即使是平面抹灰，石灰砂漿層的強度比水泥砂漿強度低，石灰砂漿又未能結硬，硬的水泥砂漿層抹在軟的石灰砂漿層上，只要一受外力，水泥砂漿層就會產生破裂現象。

If cement mortar is applied during the hardening process of lime mortar, the cement mortar will harden quickly due to the rapid hydration of cement in the cement mortar. The hardened cement mortar is equivalent to adding a layer of diaphragm on the lime mortar surface to seal the lime mortar layer, so that the lime paste can not absorb carbon dioxide in the air, and the generated water can not evaporate, In this way, the lime mortar can not harden or bond well with the surface, and the bonding force between the two is very small. The plastering of cement mortar increases the self weight of the plastering layer. Often, the self weight of the plastering layer exceeds the bonding force, and the cement mortar plastering layer and lime mortar plastering layer will be dusted down together. Even for plane plastering, the strength of lime mortar layer is lower than that of cement mortar, and the lime mortar fails to harden. When the hard cement mortar layer is plastered on the soft lime mortar layer, the cement mortar layer will crack as long as it is subjected to external force.

而且兩者都比較容易脫落。水泥砂漿在天氣潮濕時，水分凝結在表面，石灰膏的水凝聚在內部，兩者結合容易脫層，因此石灰膏下的基層，均采用水泥石灰砂漿。材料的干縮率不同。 石灰砂漿吸水，會影響水泥砂漿的強度。石灰中未完全水化的生灰會會頂裂抹灰面。石灰砂漿時間長了有析出碳酸鈣的可能。這樣就會分層了。

And both are easier to fall off. When the cement mortar is wet, the water condenses on the surface and the water of the lime paste condenses inside. The combination of the two is easy to delamination. Therefore, the base course under the lime paste adopts cement lime mortar. The dry shrinkage of materials is different. Lime mortar absorbs water, which will affect the strength of cement mortar. The incomplete hydrated quicklime in lime will crack the plastered surface. Lime mortar may precipitate calcium carbonate after a long time. This will layer.
