抹面砂漿是一種功能材料而不是結(jié)構(gòu)材料，其作用除找平墻面外，主要起保護(hù)墻體的作用。下面來講講抹面砂漿的技術(shù)要求以及所需材料事項(xiàng)吧。

Plastering mortar is a functional material rather than a structural material. Its function is not only to level the wall, but also to protect the wall. Let's talk about the technical requirements and required materials for plastering mortar.

濟(jì)南抹面砂漿的質(zhì)量終反映在其工程質(zhì)量上，目前抹面砂漿存在的主要問題是開裂、空鼓、脫落，這其中的一個(gè)主要原因是砂漿的粘結(jié)強(qiáng)度低。所以對(duì)于抹面砂漿來說粘結(jié)強(qiáng)度是一個(gè)重要的指標(biāo)。

The quality of Jinan plastering mortar is ultimately reflected in its engineering quality. Currently, the main problems with plastering mortar are cracking, hollowing, and peeling. One of the main reasons for this is the low bonding strength of the mortar. So for plastering mortar, bond strength is an important indicator.

抹面砂漿除要求具有良好的和易性，容易抹成均勻平整的薄層，便于施工；還要求具有較高的粘結(jié)力，砂漿層要能與基底粘結(jié)牢固，長(zhǎng)期使用不致開裂或脫落。

The plastering mortar should have good workability and be easy to apply into a uniform and flat thin layer for easy construction; It is also required to have a high bonding force, and the mortar layer should be able to firmly bond with the substrate, without cracking or falling off after long-term use.

好的抹面砂漿對(duì)建筑物和墻體可起保護(hù)作用，它可以抵抗風(fēng)、雨、雪等自然環(huán)境對(duì)建筑物的侵蝕，并提高建筑物的耐久性。經(jīng)過砂漿抹面的墻面或其他構(gòu)件的表面又可以達(dá)到平整、光潔和美觀的效果。

Good plastering mortar can protect buildings and walls by resisting the erosion of natural environments such as wind, rain, and snow, and improving the durability of buildings. The surface of walls or other components that have been plastered with mortar can achieve a flat, smooth, and aesthetically pleasing effect.

抹面砂漿的組成材料與砌筑砂漿基本是相同的。但為了防止砂漿層開裂，有時(shí)需加入一些纖維材料；有時(shí)為了使其具有某些功能，例如防水或保溫等功能，需要選用特殊骨料或摻合料。

The composition material of plastering mortar is basically the same as that of masonry mortar. But in order to prevent cracking of the mortar layer, it is sometimes necessary to add some fiber materials; Sometimes, in order to have certain functions, such as waterproofing or insulation, special aggregates or admixtures need to be selected.

傳統(tǒng)抹面砂漿要么和易性差，施工困難，容易導(dǎo)致疏松、開裂、滲漏；要么和易性好，但粘結(jié)力差，收縮大，不耐水，不能很好地起到保護(hù)墻體的作用。我國(guó)目前抹面砂漿還處于手工操作，勞動(dòng)強(qiáng)度大，抹灰層厚度受施工水平限制，一般在20mm，要分2~3次完成。

Traditional plastering mortar either has poor workability and is difficult to construct, which can easily lead to looseness, cracking, and leakage; Either it has good workability, but poor adhesion, large shrinkage, and is not water resistant, which cannot effectively protect the wall. At present, the plastering mortar in our country is still in manual operation, with high labor intensity. The thickness of the plastering layer is limited by the construction level, usually 20mm, and needs to be completed in 2-3 times.

粘結(jié)強(qiáng)度是抹面砂漿的一個(gè)重要指標(biāo)。砂漿只有具有一定的粘結(jié)力，砂漿層才能與基底粘結(jié)牢固，長(zhǎng)期使用不致開裂或脫落。

Bond strength is an important indicator of plastering mortar. Only when mortar has a certain bonding force can the mortar layer firmly bond with the substrate, and long-term use will not cause cracking or detachment.

雖然都認(rèn)識(shí)到粘結(jié)強(qiáng)度對(duì)抹面砂漿的重要性，但以往的標(biāo)準(zhǔn)規(guī)范中只對(duì)砂漿的粘結(jié)性能提出定性的規(guī)定，而沒有給出定量的要求。由于保水性與粘結(jié)強(qiáng)度基本成正比的關(guān)系，保水性好，粘結(jié)強(qiáng)度就高，因此該標(biāo)準(zhǔn)也對(duì)保水性提出了低的要求。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.netjobs.cc咨詢吧！

Although the importance of bonding strength for plastering mortar is recognized, previous standard specifications only provided qualitative provisions on the bonding performance of mortar, without providing quantitative requirements. Due to the proportional relationship between water retention and bonding strength, good water retention results in high bonding strength. Therefore, this standard also puts low requirements on water retention. For more related content, come to our website http://www.netjobs.cc Consult!
