水泥是水硬性材料,石灰膏是汽硬性材料, 潮濕環(huán)境中反璃，不得使用氣硬性材料鳍贾。
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(jié)材料是石灰膏，石灰膏的主要化學(xué)成分是氫氧化鈣缰猴。石灰砂漿之所以能結(jié)硬灾纱，是氫氧化鈣吸收了空氣中的二氧化碳巨揪，生成碳酸鈣及水，碳酸鈣是有一定強(qiáng)度和硬度的海泵，并且能與砂粘在一起标腮，使石灰砂漿層結(jié)硬，由于空氣中二氧化碳含量少围婴，這種化學(xué)反應(yīng)進(jìn)行緩慢祈很，而且生成的水又要蒸發(fā)掉。因此聚谁，石灰砂漿結(jié)硬是需要很長(zhǎng)時(shí)間母剥。
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(jié)硬過(guò)程中抹上水泥砂漿滞诺，水泥砂漿中由于水泥水化作用快形导，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习霹，把石灰砂漿層封閉起來(lái)朵耕，使石灰膏不能吸收空氣中二氧化碳，而且生成的水分也無(wú)法蒸發(fā)淋叶，這樣石灰砂漿始終不能結(jié)硬阎曹，也不能與物面很好地粘結(jié)，兩者之間的粘結(jié)力很小煞檩。抹上了水泥砂漿又增加了抹灰層自重处嫌，往往抹灰層自重超過(guò)粘結(jié)力，水泥砂漿抹灰層連同石灰砂漿抹灰層會(huì)一起撣落下來(lái)斟湃。即使是平面抹灰熏迹，石灰砂漿層的強(qiáng)度比水泥砂漿強(qiáng)度低，石灰砂漿又未能結(jié)硬凝赛，硬的水泥砂漿層抹在軟的石灰砂漿層上挫勿，只要一受外力，水泥砂漿層就會(huì)產(chǎn)生破裂現(xiàn)象庭授。
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琴哗。水泥砂漿在天氣潮濕時(shí)，水分凝結(jié)在表面粉只，石灰膏的水凝聚在內(nèi)部吟叙，兩者結(jié)合容易脫層，因此石灰膏下的基層暇鸦，均采用水泥石灰砂漿揍丘。材料的干縮率不同。 石灰砂漿吸水升价，會(huì)影響水泥砂漿的強(qiáng)度慢俄。石灰中未完全水化的生灰會(huì)會(huì)頂裂抹灰面茧天。石灰砂漿時(shí)間長(zhǎng)了有析出碳酸鈣的可能。這樣就會(huì)分層了妄结。
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.
