濟南抹面砂漿質量選擇的標準是什么雨担?

抹面砂漿是一種功能材料而不是結構材料隐听,其作用初找平墻面外孝生,主要起保護墻體的作用估态。抹面砂漿的質量終反映在其工程質量上替劈,目前抹灰砂漿存在的主要問題是開裂赔硫、空鼓岩调、脫落巷燥,這其中的一個主要原因是砂漿的粘結強度低,因此粘結強度對抹灰砂漿來說是一個重要指標沛狱。

Plastering mortar is a kind of functional material rather than structural material. Its function is to level the wall surface and protect the wall. The quality of plastering mortar is reflected in its engineering quality. At present, the main problems of plastering mortar are cracking, hollowing and falling off. One of the main reasons is that the bonding strength of mortar is low, so the bonding strength is an important index for plastering mortar.
抹面砂漿除要求具有良好的和易性的闹,容易抹成均勻平整的薄層,便于施工尤乎;還要求具有較高的粘結力翼养,砂漿層要能與基底粘結牢固,長期使用不致開裂或脫落波寓。好的抹灰砂漿對建筑物和墻體可起保護作用缘嗦,它可以抵抗風、雨报逛、雪等自然環(huán)境對建筑物的侵蝕烦草,并提高建筑物的耐久性。經過砂漿抹面的墻面或其他構件的表面又可以達到平整任疤、光潔和美觀的效果幽摔。
In addition to good workability, the plastering mortar is easy to be plastered into a uniform and flat thin layer, which is convenient for construction; it is also required to have a high cohesive force, and the mortar layer should be able to bond firmly with the base, and it will not crack or fall off after long-term use. Good plastering mortar can protect buildings and walls. It can resist the erosion of natural environment such as wind, rain and snow, and improve the durability of buildings. The surface of the wall or other components plastered with mortar can achieve smooth, smooth and beautiful effect.
抹面砂漿的稠度可根據基層材料決定。選用普通抹灰砂漿,應同時考慮其可操作性刮便,包括砂漿的保水性空猜、黏聚性和觸變性,以及初期抗裂性恨旱、粘結強度抄肖、抗壓強度和后期抗裂性等多重指標,不能只偏重某一指標而影響砂漿其他性能窖杀。
The consistency of plastering mortar can be determined according to the base material. When selecting common plastering mortar, its operability should be considered at the same time, including water retention, cohesiveness and thixotropy of mortar, and multiple indexes such as initial crack resistance, bond strength, compressive strength and later crack resistance. It is not allowed to focus on one index and affect other properties of mortar.
抹面砂漿的使用應根據建筑物的立面尺寸精度和墻體結構形式決定漓摩。例如,磚結構墻體因為塊體之間灰縫多入客,塊體尺寸偏差大管毙,一般就采用普通抹灰砂漿;鋼筋混凝土結構桌硫,如果模板尺寸精度偏差大或混凝土墻板與梁斷面尺寸不一致夭咬,那么也必須作普通抹灰;如果鋼筋混凝土結構基層尺寸精度偏差小铆隘,那么就可采用薄層砂漿抹灰卓舵。
The use of plastering mortar should be determined according to the vertical dimension accuracy of the building and the structural form of the wall. For example, for brick structure wall, because there are many mortar joints between blocks and the block size deviation is large, ordinary plastering mortar is generally used; for reinforced concrete structure, if the accuracy deviation of formwork size is large or the size of concrete wall panel and beam section is inconsistent, then ordinary plastering must be carried out; if the dimensional accuracy deviation of reinforced concrete structure base is small, thin-layer mortar plastering can be used.
