濟南抹面砂漿作為建筑施工中的常用材料，憑借其獨特的性能，在房屋建造中扮演著重要角色，但并非適用于所有結構部位，其應用需結合房屋建造的具體環節和功能需求。在濟南氣候條件（夏季多雨、冬季寒冷）和建筑風格影響下，抹面砂漿的合理使用既能提升墻體質量，又能增強房屋的耐久性，成為房屋建造中不可或缺的輔助材料。

　　Jinan plastering mortar, as a commonly used material in construction, plays an important role in building construction due to its unique properties. However, it is not suitable for all structural parts, and its application needs to be combined with the specific links and functional requirements of building construction. Under the influence of Jinan's climate conditions (rainy summers and cold winters) and architectural style, the reasonable use of plastering mortar can not only improve the quality of walls, but also enhance the durability of buildings, becoming an indispensable auxiliary material in building construction.

　　抹面砂漿可用于房屋墻體的表面處理，是墻面裝飾與防護的基礎。在磚石結構或混凝土墻體砌筑完成后，墻面常存在不平整、縫隙等問題，抹面砂漿通過分層涂抹（通常分底層、中層、面層），能填補墻面缺陷，使表面平整光滑，為后續裝飾（如涂漆、貼磚）提供良好基底。底層砂漿（厚度 5-10mm）側重與基層粘結，多采用水泥砂漿，利用水泥的膠凝性與墻體形成牢固結合；中層砂漿（厚度 10-15mm）主要起找平作用，可根據墻面平整度調整厚度；面層砂漿（厚度 3-5mm）則注重表面光潔度，常添加細砂或粉煤灰改善和易性，使墻面細膩平整。濟南多風天氣下，平整的墻面能減少風荷載對墻體的沖擊，同時避免雨水在墻面凹陷處積聚，降低滲漏風險。

　　Mortar can be used for surface treatment of building walls and is the foundation for wall decoration and protection. After the completion of masonry in brick and stone structures or concrete walls, there are often problems such as unevenness and gaps in the wall surface. The plastering mortar can be applied layer by layer (usually divided into bottom layer, middle layer, and surface layer) to fill the wall surface defects, making the surface flat and smooth, and providing a good foundation for subsequent decoration (such as painting and tiling). The bottom mortar (thickness 5-10mm) focuses on bonding with the base layer, often using cement mortar to form a strong bond with the wall using the cementitious properties of cement; The middle layer mortar (thickness 10-15mm) is mainly used for leveling, and the thickness can be adjusted according to the flatness of the wall surface; The surface layer mortar (thickness 3-5mm) focuses on surface smoothness, often adding fine sand or fly ash to improve workability and make the wall surface delicate and smooth. In windy weather in Jinan, a flat wall surface can reduce the impact of wind loads on the wall, while avoiding rainwater accumulation in wall depressions and reducing the risk of leakage.

　　在框架結構房屋中，抹面砂漿是填充墻與框架連接部位的重要處理材料，能增強結構整體性。框架結構的梁柱與填充墻（如加氣混凝土砌塊、空心磚）之間存在材質差異，受溫度變化影響易產生收縮裂縫，抹面砂漿施工時，需在接縫處鋪設耐堿玻纖網格布，再涂抹砂漿，利用網格布的抗拉性能抑制裂縫產生。濟南冬季寒冷，墻體易因溫度變化出現熱脹冷縮，抹面砂漿中的柔性添加劑（如可再分散乳膠粉）能提升砂漿的柔韌性（壓折比≤3.0），減少因墻體變形導致的砂漿開裂，確保墻面完整性。對于外墻，抹面砂漿還需具備一定的防水性（吸水率≤10%），能阻擋雨水滲透，保護墻體內部結構，尤其適合濟南多雨季節的房屋防護。

　　In frame structured houses, plastering mortar is an important material for filling the connection between walls and frames, which can enhance the overall structural integrity. There are material differences between the beams and columns of the frame structure and the infill walls (such as aerated concrete blocks and hollow bricks), which are prone to shrinkage cracks due to temperature changes. When applying mortar, alkali resistant fiberglass mesh cloth should be laid at the joints, and then mortar should be applied to use the tensile properties of the mesh cloth to suppress crack formation. Jinan is cold in winter, and walls are prone to thermal expansion and contraction due to temperature changes. Flexible additives (such as redispersible latex powder) in the plastering mortar can enhance the flexibility of the mortar (compression ratio ≤ 3.0), reduce mortar cracking caused by wall deformation, and ensure the integrity of the wall. For exterior walls, the plastering mortar also needs to have a certain degree of waterproofing (water absorption rate ≤ 10%), which can block rainwater infiltration and protect the internal structure of the wall, especially suitable for building protection during the rainy season in Jinan.

　　抹面砂漿可用于房屋的保溫層防護，是保溫系統的重要組成部分。濟南新建房屋多采用外墻外保溫系統，保溫層（如聚苯板、巖棉板）外側需涂抹抹面砂漿，形成防護層，保護保溫材料免受外界環境侵蝕。這類抹面砂漿需具備與保溫層的良好粘結力（拉伸粘結強度≥0.1MPa），同時有足夠的抗沖擊性（抗沖擊強度≥3J），能抵御外力撞擊（如施工碰撞、風吹雜物沖擊），避免保溫層破損。冬季濟南氣溫較低，抹面砂漿需能承受 - 15℃至 30℃的溫度波動，經凍融循環（25 次以上）后無空鼓、剝落，確保保溫系統長期有效，減少房屋能耗損失。

　　Plaster mortar can be used for the insulation layer protection of houses and is an important component of the insulation system. Newly built houses in Jinan often use external wall insulation systems. The outer side of the insulation layer (such as polystyrene board and rock wool board) needs to be coated with mortar to form a protective layer, which protects the insulation material from external environmental erosion. This type of plastering mortar needs to have good bonding strength with the insulation layer (tensile bonding strength ≥ 0.1MPa), as well as sufficient impact resistance (impact strength ≥ 3J), able to resist external impact (such as construction collision, wind blown debris impact), and avoid damage to the insulation layer. In winter, the temperature in Jinan is relatively low, and the plastering mortar needs to be able to withstand temperature fluctuations of -15 ℃ to 30 ℃. After freeze-thaw cycles (more than 25 times), there should be no hollowing or peeling, ensuring the long-term effectiveness of the insulation system and reducing energy consumption losses in the house.

　　不過，抹面砂漿不能作為房屋的承重結構材料，無法替代磚、混凝土等主體結構材料。其主要成分是水泥、砂、添加劑等，雖然硬化后有一定強度（抗壓強度≥5MPa），但抗拉強度低，無法承受房屋自重及外部荷載，若用于承重部位，會導致結構安全隱患。在濟南房屋建造中，抹面砂漿僅能作為輔助材料，用于非承重墻體的表面處理、保溫層防護等，而承重墻、梁柱等關鍵結構部位仍需依靠鋼筋混凝土、磚石等承重材料，兩者分工不同，共同保障房屋的安全與穩定。

　　However, plastering mortar cannot be used as a load-bearing structural material for houses and cannot replace main structural materials such as bricks and concrete. Its main components are cement, sand, additives, etc. Although it has a certain strength after hardening (compressive strength ≥ 5MPa), its tensile strength is low and cannot withstand the self weight of the building and external loads. If used in load-bearing parts, it can cause structural safety hazards. In the construction of houses in Jinan, plastering mortar can only be used as an auxiliary material for surface treatment of non load bearing walls, insulation layer protection, etc., while key structural parts such as load-bearing walls, beams, and columns still rely on load-bearing materials such as reinforced concrete and bricks. The two have different responsibilities and work together to ensure the safety and stability of the house.

　　濟南抹面砂漿的使用需適配本地建筑材料特性，確保施工效果。濟南地區常用的墻體材料有加氣混凝土砌塊、普通黏土磚等，抹面砂漿需根據基層材料調整配方：針對加氣混凝土砌塊的高吸水性，砂漿需提高保水性（保水率≥88%），避免因失水過快導致空鼓；對于黏土磚墻體，砂漿可適當提高水泥用量，增強粘結強度。施工時需控制環境溫度（5-35℃），濟南夏季高溫時需避開正午施工，防止砂漿失水過快產生裂紋；冬季施工則需采取保溫措施，確保砂漿在正溫下硬化，避免受凍影響強度發展。

　　The use of Jinan plastering mortar needs to be adapted to the characteristics of local building materials to ensure construction effectiveness. The commonly used wall materials in Jinan area include aerated concrete blocks, ordinary clay bricks, etc. The formula of the plastering mortar needs to be adjusted according to the base material: for the high water absorption of aerated concrete blocks, the mortar needs to improve its water retention (water retention rate ≥ 88%) to avoid hollowing caused by rapid water loss; For clay brick walls, the amount of cement used in mortar can be appropriately increased to enhance the bonding strength. During construction, it is necessary to control the ambient temperature (5-35 ℃), and avoid working at noon during high temperatures in Jinan in summer to prevent the mortar from losing water too quickly and causing cracks; During winter construction, insulation measures should be taken to ensure that the mortar hardens at positive temperatures and to avoid the impact of freezing on strength development.
