抹面砂浆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；还应有较高的黏结力，不易开裂或脱落。下面来讲讲济南抹面砂浆的原材料事项。

The plastering mortar should have good workability and be easy to apply into a uniform and flat thin layer for easy construction; It should also have a high bonding force, which is not easy to crack or fall off. Next, let's talk about the raw materials of Jinan plastering mortar.

胶凝材料

Cementitious material

抹面砂浆常用的胶凝材料有硅酸盐水泥、铝酸盐水泥、石膏、石灰、树脂、沥青等。将着色剂混入白色水泥或者硅酸盐水泥中制备而成的彩色水泥，可以应用于各种装饰墙体。

Cement materials commonly used for plastering mortar include Portland cement, Aluminate cement, gypsum, lime, resin, asphalt, etc. Colored cement prepared by mixing colorants with white cement or Portland cement can be applied to various decorative walls.

细骨料

Fine aggregate

抹面砂浆用细骨料主要分为天然砂、机制砂和工业废渣，其中，轻骨料抹面砂浆常用的细骨料主要分为天然轻骨料、人造轻骨料和工业废渣轻骨料三类。

Fine aggregates used for plastering mortar are mainly divided into natural sand, machine made sand, and industrial waste. Among them, the commonly used fine aggregates for lightweight aggregate plastering mortar are mainly divided into three categories: natural lightweight aggregate, artificial lightweight aggregate, and industrial waste lightweight aggregate.

掺合料

Admixture

在抹面砂浆中加入适量掺合料，能改善砂浆的和易性，达到方便施工、降低成本的目的。常用的掺合料有粉煤灰、粒化高炉矿渣、硅灰、沸石粉等。

Adding an appropriate amount of admixture to the plastering mortar can improve the workability of the mortar, achieve the goal of convenient construction and cost reduction. Commonly used admixtures include fly ash, granulated blast furnace slag, silica fume, zeolite powder, etc.

粉煤灰具有潜在化学活性，颗粒较细，掺入抹面砂浆中可以发挥活性效应、形态效应和填充效应；粒化高炉矿渣应用在抹面砂浆中，有利于其中的活性组分更快、更充分水化；硅灰用在抹面砂浆中可以提高砂浆的强度，配制出高强砂浆。

Fly ash has potential chemical activity, with relatively fine particles. When added to plastering mortar, it can exert activity, morphology, and filling effects; The application of granulated blast furnace slag in plastering mortar is conducive to faster and more complete hydration of the active components; The use of silica fume in plastering mortar can improve the strength of the mortar and prepare high-strength mortar.

同时，还可以改善砂浆的孔结构，提高抗渗性、抗冻性以及耐腐蚀性；抹面砂浆中加入沸石可以减少砂浆泌水，改善可泵性，还可以提高砂浆强度、密实性、抗渗性和抗冻性。

At the same time, it can also improve the pore structure of mortar, improve its impermeability, frost resistance, and corrosion resistance; Adding zeolite to plastering mortar can reduce mortar bleeding, improve pumpability, and also improve mortar strength, compactness, impermeability, and frost resistance.

外加剂

admixture

外加剂可以改善砂浆性能，常用的外加剂有：聚合物乳液、可再分散乳胶粉、纤维素醚、触变润滑剂、减水剂、引气剂、早强剂、调凝剂、防水剂、防冻剂等。

Admixtures can improve the performance of mortar. Common admixtures include polymer lotion, redispersible emulsion powder, cellulose ether, thixotropic lubricant, water reducer, air entraining agent, early strength agent, setting modifier, waterproof agent, Antifreeze, etc.

抹面砂浆中应用广的聚合物乳液为醋酸乙烯-乙烯共聚物乳液，多用于外墙保温；纯丙乳液和苯丙乳液常用于防水砂浆和修补抹面砂浆中；可再分散乳胶粉可以提高抹面砂浆的拉伸黏结强度、抗折强度、变形能力、耐磨强度等；纤维素醚应用于抹面砂浆中可起到保水、增稠、引气、改善施工性能等方面的作用；膨润土作为触变润滑剂，可以增加抹面砂浆的稳定性，改善可泵性；减水剂、引气剂、早强剂、调凝剂、防冻剂等对抹面砂浆起到减水、引气、早强、缓凝、速凝、抗冻的作用。

The widely used polymer lotion in plastering mortar is vinyl acetate vinyl copolymer lotion, which is mostly used for external wall insulation; Pure acrylic lotion and styrene acrylic lotion are commonly used in waterproof mortar and repair plaster mortar; Redispersible latex powder can improve the tensile bonding strength, flexural strength, deformation ability, and wear resistance of plastering mortar; The application of cellulose ether in plastering mortar can play a role in water retention, thickening, air entrainment, and improving construction performance; Bentonite, as a thixotropic lubricant, can increase the stability of plastering mortar and improve its pumpability; Water reducing agent, air entraining agent, early strength agent, setting regulator, Antifreeze, etc. play the role of water reducing, air entraining, early strength, retarding, rapid setting, and antifreeze on the plastering mortar.

在抹面砂浆中加入纤维可以改善其抗裂、抗爆裂、抗冻融、抗冲击、耐磨等性能。用来提高抹面砂浆抗裂性的纤维主要为耐碱玻璃纤维和有机合成纤维（如聚丙烯纤维、聚丙烯膳纤维、聚乙烯醇纤维等）。还有什么事儿就来我们网站//www.gochiism.com咨询！

Adding fibers to the plaster mortar can improve its properties such as crack resistance, burst resistance, freeze-thaw resistance, impact resistance, and wear resistance. The fibers used to improve the crack resistance of plastering mortar are mainly alkali resistant glass fiber and organic Synthetic fiber (such as polypropylene fiber, polypropylene fiber, polyvinyl alcohol fiber, etc.).
