自流平砂浆是一种干混型粉状材料，由多种活性成分组成，硬化速度快、流动性好。主要组成部分有普硅水泥、高铝水泥、硅酸盐水泥、活性酵母激发剂等。下面来讲讲济南自流平砂浆施工期间的重要事项吧。

Self leveling mortar is a dry mixed powder material composed of a variety of active ingredients, with fast hardening speed and good fluidity. The main components include ordinary silicon cement, high alumina cement, Portland cement, active yeast activator, etc. Let's talk about important issues during the construction of Jinan self-leveling mortar.

（1）保证施工器具清洁，不能混入其他材料搅拌，应严格控制材料与水的比例，石膏基自流平砂浆：水=1:0.35~0.40，充分搅拌浆料使内部精料分散均匀，保证石膏基自流平砂浆流动性的同时不造成浆体离析。

(1) Ensure that the construction equipment is clean and cannot be mixed with other materials for mixing. The ratio of materials to water should be strictly controlled. Gypsum based self-leveling mortar: water=1:0.35-0.40. Fully mix the slurry to evenly disperse the internal fine materials, ensuring the fluidity of gypsum based self-leveling mortar without causing slurry segregation.

（2）基层含水率应＜8%，含水率较大会影响界面剂成膜，且后期水汽蒸发降低石膏基自流平砂浆粘结力，待界面剂成膜干燥后再进行施工。

(2) The moisture content of the base layer should be less than 8%. A large moisture content will affect the film formation of the interfacial agent, and the later water vapor evaporation will reduce the adhesive force of the stone plaster based self-leveling mortar. The construction can be carried out after the film formation of the interfacial agent is dried.

（3）应根据场地情况、施工情况、施工厚度等设置好分区线，分区线内的区域应在初凝时间内浇筑完毕，未连续浇筑将形成接茬，影响整体平整度。

(3) Zoning lines should be set according to site conditions, construction conditions, construction thickness, etc. The areas within the zoning line should be poured within the initial setting time. Discontinuous pouring will form joints and affect the overall flatness.

（4）自流平石膏搅拌后应在30min内使用完毕，超过操作时间砂浆流动性会急剧下降，失去操作性。

(4) After mixing, the self-leveling gypsum should be used within 30 minutes. After the operation time, the fluidity of the mortar will decrease sharply and the operability will be lost.

（5）已浇筑完成的禁止再次调整，未浇筑平整的自流平砂浆应在干燥后进行界面处理后再进行下一层浇筑。

(5) It is prohibited to adjust the poured mortar again. The self-leveling mortar that has not been poured and leveled should be dried and undergo interface treatment before pouring the next layer.

（6）浇筑前必须做界面处理，以降低基层吸水率，基层吸水后会造成丧失流动性，蜂窝、鼓泡等现象。

(6) Before pouring, interface treatment must be carried out to reduce the water absorption rate of the base layer. After the base layer absorbs water, it may cause loss of fluidity, honeycomb, blistering, and other phenomena.

（7）施工完成后，避免扰动，不能有穿堂风，以免造成局部过早干燥；夏季炎热温度较高时，宜选择夜间进行施工；在寒冷的情况下，使用温水（水温不超过35℃）搅拌。

(7) After construction is completed, avoid disturbance and avoid ventilation to avoid premature drying of parts; When the summer is hot and the temperature is high, it is advisable to choose night construction; In cold conditions, stir with warm water (water temperature not exceeding 35 ℃).

（8）若下一工序与石膏基自流平砂浆接触面为水泥基产品，应在石膏基自流平砂浆干燥后，做表面封闭处理；有机类饰面层不能施工于石膏基自流平砂浆上。

(8) If the contact surface between the next process and the gypsum based self-leveling mortar is a cement based product, the surface shall be sealed after the gypsum based self-leveling mortar is dried; Organic finishing layers cannot be applied to gypsum based self-leveling mortar.

（9）石膏基自流平砂浆干燥后（含水率≤1.0%）才能进行下一工序施工，需保证抹灰石膏含水率低于8%，否则会造成下一工序粘结力降低。

(9) The gypsum based self-leveling mortar can only be constructed in the next process after drying (moisture content ≤ 1.0%). It is necessary to ensure that the moisture content of the plastering gypsum is lower than 8%, otherwise the adhesive force in the next process will be reduced.

（10）新搅拌的浆体与已经过了操作时间的浆体，严禁混合搅拌，避免产生操作时间急剧缩短、开裂等现象，做到每次搅拌的料使用干净。

(10) It is strictly prohibited to mix the newly stirred slurry with the slurry that has passed the operation time, to avoid sharp shortening of the operation time, cracking, and other phenomena, and to ensure that the material used for each mixing is clean.

（11）石膏基自流平砂浆施工厚度应≥5mm，厚度过薄将影响石膏基自流平砂浆的流平性，影响石膏基自流平砂浆的水化硬化，降低成品的终强度。

(11) The construction thickness of gypsum based self-leveling mortar should be ≥ 5mm. If the thickness is too thin, it will affect the leveling property of gypsum based self-leveling mortar, affect the hydration and hardening of gypsum based self-leveling mortar, and reduce the final strength of the finished product.
