墻面抹面沙漿強(qiáng)度低、標(biāo)號(hào)不夠、脫沙掉粉、空鼓開(kāi)裂、凹凸不平……出現(xiàn)以上情況,不少人都會(huì)感覺(jué)攤上大事了！簡(jiǎn)直就像是豆腐渣工程。不過(guò)，若只是表面這些現(xiàn)象也可能沒(méi)你想像的那么嚴(yán)重，只要主體結(jié)構(gòu)沒(méi)毛病，這些表像的問(wèn)題是相對(duì)容易解決的。
The strength of the wall plastering mortar is low, the label is not enough, the sand and powder have fallen off, the hollowing and cracking, and the unevenness... Many people will feel like a big deal has been laid out! It's like a Tofu-dreg project. However, if only on the surface, these phenomena may not be as serious as you imagine. As long as the main structure is not faulty, these surface problems are relatively easy to solve.
墻面脫沙掉粉，當(dāng)然是抹面沙漿強(qiáng)度低，標(biāo)號(hào)不夠引起的。而墻面沙漿層空鼓、開(kāi)裂，又恰恰可能是抹面沙漿中水泥用量過(guò)大或強(qiáng)度過(guò)高造成，特別是開(kāi)裂。（這里要注意的是：分清是墻面沙漿開(kāi)裂還是主體墻開(kāi)裂？主體墻開(kāi)裂不在此列）。
The peeling of sand and powder on the wall is of course caused by the low strength of the plastering mortar and insufficient labeling. And the hollowing and cracking of the wall mortar layer may be caused by excessive cement content or strength in the plastering mortar, especially cracking. (It should be noted that distinguishing between wall mortar cracking and main wall cracking is not included here.).
So how to solve the low strength of Jinan plastering mortar?
如上述，墻面抹面沙漿強(qiáng)度低就會(huì)導(dǎo)致墻面脫沙掉粉。要解決這一問(wèn)題很簡(jiǎn)單，使用沙干凈就可以了，抹面沙漿強(qiáng)度低就用沙干凈。
As mentioned above, low strength of wall plastering mortar can cause the wall to lose sand and powder. To solve this problem, it is simple to use sand to clean it, and if the strength of the plaster mortar is low, use sand to clean it.
引起沙漿層空鼓開(kāi)裂，排除主體墻結(jié)構(gòu)問(wèn)題外，多數(shù)是因?yàn)樯碀{強(qiáng)度過(guò)高，即水泥沙子配比時(shí)水泥用量過(guò)大，各位有心的朋友可以留意一下，墻體沙漿強(qiáng)度越高的，裂紋裂縫越多、越明顯。
The reason for the hollowing and cracking of the mortar layer, excluding the structural problems of the main wall, is mostly due to the high strength of the mortar, that is, the excessive amount of cement used in the cement sand ratio. Interested friends can pay attention to this. The higher the strength of the mortar on the wall, the more and more obvious the cracks and cracks.
沙漿層空鼓，一般是指墻體基層與抹面沙漿層之間粘結(jié)不牢，或是抹面沙漿密實(shí)度不足導(dǎo)致的脫層現(xiàn)象。
The hollowing of the mortar layer generally refers to the phenomenon of loose bonding between the wall base and the plastering mortar layer, or delamination caused by insufficient compactness of the plastering mortar.
修復(fù)方法：
Repair method:
(1)清掃墻體表面的浮沙浮灰，將沙干凈墻面脫沙修復(fù)液攪拌均勻，然后噴涂于墻面，使墻面充分濕潤(rùn)，以不流走為宜，中度或重度脫沙的抹灰墻間隔30分鐘后噴涂第二遍（吸料滲透過(guò)快的間隔10-20分鐘，具體以現(xiàn)場(chǎng)測(cè)試為準(zhǔn)）。8小時(shí)后檢查，若局部未達(dá)到效果的，分析原因或進(jìn)行第三次噴涂補(bǔ)料。
(1) Clean the floating sand and floating ash on the surface of the wall, mix the sand clean and sand removal repair solution evenly, and then spray it on the wall to make it fully wet, preferably without flowing away. For plastered walls with moderate or severe sand removal, spray the second coat after an interval of 30 minutes (the interval for rapid material absorption and penetration is 10-20 minutes, subject to on-site testing). After 8 hours of inspection, if the effect is not achieved locally, analyze the cause or conduct a third spray repair.
(2)對(duì)于年久已風(fēng)化、抹面沙漿中水泥失效（或水泥含量過(guò)分太低的）或沙子泥土含量過(guò)大引起的抹灰層脫沙問(wèn)題，這類(lèi)情況會(huì)影響“沙干凈”效果，此類(lèi)墻面需將舊抹灰層鏟除，重新抹灰。
(2) For plastering layers that have weathered for a long time, have cement failure in the plastering mortar (or have too low cement content), or have excessive sand and soil content, which can affect the "sand cleaning" effect, such walls need to be removed from the old plastering layer and re plastered.
水泥墻面標(biāo)號(hào)不足，抹灰墻面硬度差，增加墻面硬度，墻面脫沙掉灰，墻壁掉沙起砂，毛坯房掉沙翻砂，提高水泥墻面標(biāo)號(hào)，內(nèi)外抹灰墻面掉灰，改變水泥沙漿強(qiáng)度，水泥沙漿強(qiáng)度不達(dá)標(biāo)，墻面松軟掉沙，增加強(qiáng)度密度，水泥砂漿標(biāo)號(hào)不足低、解決墻面脫沙掉粉，墻面起砂翻沙，清水墻面掉沙起砂，搓砂墻面掉灰脫沙，舊墻翻新，墻面空鼓脫皮。
Insufficient cement wall markings, poor plastering wall hardness, increased wall hardness, wall detachment and dust removal, wall detachment and dust removal, rough room detachment and sand turning, increased cement wall markings, internal and external plastering wall detachment, changed cement mortar strength, cement mortar strength not meeting standards, wall looseness and sand falling, increased strength density, insufficient cement mortar markings, solution to wall detachment and dust removal, wall detachment and sand turning, clear water wall detachment and sand turning, Dust and sand fall off the sanded wall, old walls are renovated, and the walls are hollowed and peeled off.
