抹面砂浆是一种功能材料而不是结构材料，其作用除找平墙面外，主要起保护墙体的作用。下面来讲讲抹面砂浆的技术要求以及所需材料事项吧。

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.

济南抹面砂浆的质量终反映在其工程质量上，目前抹面砂浆存在的主要问题是开裂、空鼓、脱落，这其中的一个主要原因是砂浆的粘结强度低。所以对于抹面砂浆来说粘结强度是一个重要的指标。

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.

抹面砂浆除要求具有良好的和易性，容易抹成均匀平整的薄层，便于施工；还要求具有较高的粘结力，砂浆层要能与基底粘结牢固，长期使用不致开裂或脱落。

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.

好的抹面砂浆对建筑物和墙体可起保护作用，它可以抵抗风、雨、雪等自然环境对建筑物的侵蚀，并提高建筑物的耐久性。经过砂浆抹面的墙面或其他构件的表面又可以达到平整、光洁和美观的效果。

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.

抹面砂浆的组成材料与砌筑砂浆基本是相同的。但为了防止砂浆层开裂，有时需加入一些纤维材料；有时为了使其具有某些功能，例如防水或保温等功能，需要选用特殊骨料或掺合料。

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.

传统抹面砂浆要么和易性差，施工困难，容易导致疏松、开裂、渗漏；要么和易性好，但粘结力差，收缩大，不耐水，不能很好地起到保护墙体的作用。我国目前抹面砂浆还处于手工操作，劳动强度大，抹灰层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.

粘结强度是抹面砂浆的一个重要指标。砂浆只有具有一定的粘结力，砂浆层才能与基底粘结牢固，长期使用不致开裂或脱落。

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.

虽然都认识到粘结强度对抹面砂浆的重要性，但以往的标准规范中只对砂浆的粘结性能提出定性的规定，而没有给出定量的要求。由于保水性与粘结强度基本成正比的关系，保水性好，粘结强度就高，因此该标准也对保水性提出了低的要求。更多相关内容就来我们网站//www.gochiism.com咨询吧！

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 //www.gochiism.com Consult!
