                         ★ 施工要点 ： 
                         （一） 基础处理和支模 ： 
                         　　1、混凝土基础表面凿毛、并将其清理干净。与座浆料粘合在一起的构件（如钢垫板）将锈皮及 
                         　　　 油污等清除掉。 
                         　　2、在浇灌座浆料前4小时，对混凝土基础表面施于湿润， 浇灌时不得有积水。 
                         　　3、挡板应支设严密，防止漏浆。 
                         （二） 灌浆 ： 
                         　　1、加水量：按照每袋(25kg)用水4.0~4.5kg的比例加水搅拌，如施工不需要较大流动度可相 
                         　　　 应减少用水量。 
                         　　2、搅拌程序：在搅拌桶内加入规定量的水后置入搅拌器，将一部分座浆料倒入桶内搅稀，再将 
                         　     余料倒入搅拌，时间从开始到结束宜控制在一分钟左右。 
                         　　3、搅拌时，叶片应沿着桶周边上下左右缓慢移动，以使桶底和桶壁粘附的干料得以拌和；搅拌 
                         　     叶片不得提至座浆料液面之上，以免空气带入座浆料内。 
                         　　4、搅拌好的座浆料胶泥应及时浇灌。浇灌时，尽可能从一侧注入，以利排出底板与混凝土基础 
                         　     之间的空气。必要时，可采用竹片等工具导流。 浇灌开始后必须连续进行，不能间断。 
                         ★ 搅拌机具 ： 
                         　　① 双柄手电钻，功率≥450W,转速≥500r/min。 
                         　　② 搅拌叶片用δ＝1.2mm厚钢板制成，叶片φ150mm,搅拌杆φ12mm圆钢。 
                         ★ 注意事项 ： 
                         　　现场使用时，严禁在胶泥中掺入任何外加剂、外掺剂。不得与其他厂家生产的类似产品混用，以确保工程质量。 
                         ★ 养护 ： 
                         　　1、用湿润的草袋或布覆盖在已浇灌好的座浆料上，并洒水养护，每天2-6次。 
                         　　2、养护温度应在15℃以上，养护期7天。若现场温度较低时可适当延长养护期。 
                         　　3、冬季施工需采取保温措施。 
                         ★ 拆模 ： 
                         　　拆模应在浇灌完毕24小时后进行，拆模后仍继续养护。 
                         ★ 包装及储运 ： 
                         　　包装规格为25kg±0.5kg，用复合纸袋内衬塑料袋包装。储存在干燥、阴凉处，在未经受潮保存下储存期为三个月。超期需复检，合格后才可使用。
