抹面砂浆作为建筑工程中用于基层表面处理的关键材料，其适用范围与地域气候、建筑类型及施工需求密切相关。济南地处温带季风气候区，夏季高温多雨，冬季寒冷干燥，且建筑风格涵盖现代楼宇、老旧民居及市政设施，这使得抹面砂浆的选用需兼顾功能性与环境适应性。以下从不同建筑场景出发，解析济南抹面砂浆的具体适用范围。

　　As a key material used for surface treatment of the base layer in construction projects, the application scope of plastering mortar is closely related to regional climate, building type, and construction requirements. Jinan is located in a temperate monsoon climate zone, with hot and rainy summers and cold and dry winters. The architectural style covers modern buildings, old residential buildings, and municipal facilities, which requires the selection of plastering mortar to balance functionality and environmental adaptability. Starting from different architectural scenarios, analyze the specific scope of application of Jinan plastering mortar.

　　民用建筑的内外墙面处理

　　Interior and exterior wall treatment of civil buildings

　　在济南的民用建筑中，抹面砂浆的应用贯穿于新建住宅与存量住宅的多个部位。外墙施工是其核心应用场景之一，考虑到济南夏季多雨、冬季多风的特点，外墙抹面砂浆需具备良好的抗渗性与抗冻性。普通抹面砂浆可用于外墙基层找平，配合防水添加剂后，能有效阻隔雨水渗透，尤其适合小高层及多层住宅的外墙处理。对于采用外墙外保温系统的建筑，专用保温抹面砂浆（如聚合物抹面砂浆）可紧密包裹保温层，形成防护面层，其粘结强度达 0.6MPa 以上，能抵御济南春秋季的强风荷载。

　　In civil buildings in Jinan, the application of plastering mortar runs through multiple parts of newly built and existing residential buildings. Exterior wall construction is one of its core application scenarios. Considering the rainy summers and windy winters in Jinan, exterior wall plastering mortar needs to have good impermeability and frost resistance. Ordinary plastering mortar can be used for leveling the exterior wall base, and when combined with waterproof additives, it can effectively block rainwater infiltration, especially suitable for exterior wall treatment of small high-rise and multi story residential buildings. For buildings that use external wall insulation systems, specialized insulation plaster mortar (such as polymer plaster mortar) can tightly wrap around the insulation layer to form a protective surface layer, with a bonding strength of over 0.6 MPa, which can withstand strong wind loads in spring and autumn in Jinan.

　　内墙及顶棚抹面则更注重平整度与环保性。住宅室内墙面、厨房及卫生间的干燥区域，可使用水泥砂浆或混合砂浆进行抹面，既便于后续贴砖或刷漆，又能通过调整砂灰比控制表面硬度。济南老城区的四合院改造中，传统石灰砂浆仍常用于内墙抹面，其透气性好的特点可适应老建筑砖木结构的防潮需求，避免基层受潮霉变。

　　The plastering of interior walls and ceilings places more emphasis on flatness and environmental friendliness. The dry areas of residential interior walls, kitchens, and bathrooms can be plastered with cement mortar or mixed mortar, which is convenient for subsequent tiling or painting, and can also control surface hardness by adjusting the sand cement ratio. In the renovation of courtyard houses in the old city area of Jinan, traditional lime mortar is still commonly used for interior wall plastering. Its good breathability can meet the moisture-proof needs of brick and wood structures in old buildings and prevent the base from getting damp and moldy.

　　工业建筑的防护与功能性处理

　　Protection and functional treatment of industrial buildings

　　济南作为工业重镇，各类厂房、仓库等工业建筑对抹面砂浆的功能性有特殊要求。在机械加工车间，墙面及柱体表面需采用高强度抹面砂浆（抗压强度≥15MPa），以抵御设备运行时的震动与碰撞，同时其表面光滑度可减少粉尘附着，便于日常清洁。对于食品加工厂区，抹面砂浆需具备防霉特性，通过添加无机抗菌剂，可有效抑制济南夏季高温高湿环境下霉菌的滋生，保障生产环境达标。

　　Jinan, as an industrial hub, has special requirements for the functionality of plastering mortar in various industrial buildings such as factories and warehouses. In the mechanical processing workshop, high-strength plastering mortar (compressive strength ≥ 15MPa) should be used on the walls and column surfaces to resist vibration and collision during equipment operation. At the same time, its surface smoothness can reduce dust adhesion and facilitate daily cleaning. For food processing plants, the plastering mortar needs to have anti mold properties. By adding inorganic antibacterial agents, it can effectively inhibit the growth of mold in the high temperature and high humidity environment of Jinan in summer, ensuring that the production environment meets the standards.

　　仓储建筑的地面与墙面处理也离不开抹面砂浆。济南的大型物流仓库多采用混凝土基层，地面抹面砂浆需兼具耐磨性与抗渗性，以应对叉车频繁碾压及雨水渗漏问题。而存放化工原料的仓库外墙，常使用耐酸碱抹面砂浆，其惰性材料成分可抵抗腐蚀性气体侵蚀，适应济南化工园区周边的特殊环境。

　　The ground and wall treatment of storage buildings also relies on plastering mortar. Large logistics warehouses in Jinan often use concrete base, and the ground plastering mortar needs to have both wear resistance and impermeability to cope with frequent forklift crushing and rainwater leakage problems. The exterior walls of warehouses storing chemical raw materials often use acid and alkali resistant plastering mortar, whose inert material composition can resist corrosive gas erosion and adapt to the special environment around Jinan Chemical Industry Park.

　　市政工程的耐久性需求场景

　　Durability demand scenarios for municipal engineering

　　市政设施是济南抹面砂浆的重要应用领域，其适用性需满足户外环境的长期考验。城市道路两侧的挡土墙、涵洞等结构，表面抹面砂浆需具备抗冻融性能，济南冬季最低气温可达 - 10℃，经过抗冻性测试的砂浆（经 25 次冻融循环强度损失≤15%）可有效防止基层受冻开裂。在泉城广场、大明湖周边等景观区域，彩色抹面砂浆被广泛用于花坛、雕塑基座的表面装饰，其色彩稳定性可抵御济南夏季强紫外线照射，保持外观持久鲜艳。

　　Municipal facilities are an important application area for Jinan plastering mortar, and its applicability needs to meet the long-term test of outdoor environment. The retaining walls, culverts and other structures on both sides of urban roads need to have anti freezing and thawing properties for the surface plastering mortar. The lowest temperature in winter in Jinan can reach -10 ℃. The mortar that has undergone anti freezing tests (with a strength loss of ≤ 15% after 25 freeze-thaw cycles) can effectively prevent the base from cracking due to freezing. Colored plaster mortar is widely used for surface decoration of flower beds and sculpture bases in scenic areas such as Quancheng Square and Daming Lake. Its color stability can resist strong ultraviolet radiation in Jinan summer and maintain a long-lasting and bright appearance.

　　桥梁及地下通道的维护同样依赖抹面砂浆。济南黄河大桥的桥墩侧面修补中，聚合物改性抹面砂浆可紧密粘结于混凝土基层，形成防水保护层，减少河水蒸发带来的盐雾侵蚀；地下通道的侧墙与顶板抹面则需兼具透气性与抗渗性，避免冷凝水积聚导致的基层返潮，这类场景多选用掺加引气剂的抹面砂浆，通过微小气泡调节水汽平衡。

　　The maintenance of bridges and underground passages also relies on plastering mortar. In the side repair of the bridge piers of Jinan Yellow River Bridge, polymer modified plaster mortar can be tightly bonded to the concrete base to form a waterproof protective layer, reducing salt spray erosion caused by river water evaporation; The side walls and roof plastering of underground passages need to have both breathability and impermeability to avoid moisture regain at the base caused by the accumulation of condensed water. In such scenarios, plastering mortar mixed with air entraining agents is often used to adjust water vapor balance through tiny bubbles.

　　老旧建筑改造的修复场景

　　Restoration scenarios for renovating old buildings

　　济南老城区存在大量上世纪七八十年代的老旧建筑，这类建筑的翻新改造中，抹面砂浆的应用需兼顾修复功能与历史风貌保护。在芙蓉街、曲水亭街等历史文化街区的民居修缮中，传统混合砂浆（石灰、砂、水按比例调配）被用于外墙抹面，其强度适中、收缩率小的特点可与老旧砖墙基层兼容，避免因材料刚性过强导致墙体开裂。同时，为提升老建筑的保温性能，内墙可采用保温抹面砂浆，配合保温层形成复合体系，适应济南冬季采暖需求。

　　There are a large number of old buildings from the 1970s and 1980s in the old urban area of Jinan. In the renovation and renovation of such buildings, the application of plastering mortar needs to balance restoration function and historical preservation. In the renovation of residential buildings in historical and cultural districts such as Furong Street and Qushuiting Street, traditional mixed mortar (lime, sand, and water mixed in proportion) is used for exterior wall plastering. Its moderate strength and low shrinkage rate can be compatible with old brick wall bases, avoiding wall cracking caused by excessive material rigidity. At the same time, to improve the insulation performance of old buildings, insulation plaster mortar can be used for the interior walls, combined with insulation layers to form a composite system that meets the heating needs of Jinan in winter.

　　老旧小区的阳台、露台改造也是抹面砂浆的重要应用场景。这些区域长期受雨水冲刷，原基层易出现起砂、空鼓，采用防水抹面砂浆（抗渗等级≥P6）进行修补后，可形成连续的防水膜，解决渗漏问题。对于加装电梯的老旧楼宇，电梯井道的外壁抹面需使用快硬型砂浆，其 24 小时抗压强度可达 10MPa 以上，能缩短施工周期，减少对居民生活的影响。

　　The renovation of balconies and terraces in old residential areas is also an important application scenario for plastering mortar. These areas have been washed away by rainwater for a long time, and the original base layer is prone to sanding and hollowing. After repairing with waterproof plastering mortar (anti-seepage grade ≥ P6), a continuous waterproof membrane can be formed to solve the leakage problem. For old buildings with installed elevators, the outer wall of the elevator shaft needs to be coated with fast hardening mortar, which has a 24-hour compressive strength of over 10MPa, which can shorten the construction period and reduce the impact on residents' lives.
