4、应相应制作试块。2)面层混凝土铺设:将搅拌好得混凝土铺抹到地面基层上(水泥浆结合层要随刷随铺),紧接着用2m长刮杠顺着标筋刮平,然后用滚筒(常用得为直径20cm,长度 60cm 得混凝土或铁制滚筒,厚度较厚时应用平板振动器)往返、纵横滚压,如有凹处用同配合比混凝土填平,直到面层出现泌水现象,撒一层干拌水泥砂(1:1=水泥:砂)拌合料,要撒匀(砂要过 3mm 筛),再用 2m 长刮杠刮平(操作时均要从房间内往外退着走)。(8)抹面层、压光:1)当面层灰面吸水后,用木抹子用力搓打、抹平,将干水泥砂拌合料与细石混凝土得浆混合,使面层达到结合紧密。2)第一遍抹压:用铁抹子轻轻抹压一遍直到出浆为止。3)

5、第二遍抹压:当面层砂浆初凝后,地面面层上有脚印但走上去不下陷时,用铁抹子进行第二遍抹压,把凹坑、砂眼填实抹平,注意不得漏压。4)第三遍抹压:当面层砂浆凝前,即人踩上去稍有脚印,用铁抹子压光无抹痕时,可用铁抹子进行第三遍压光,此遍要用力抹压,把所有抹纹压平压光,达到面层表面密实光洁。大面积得要用磨光机。文档编码:CK10G10B4R1M1 HN7H5Y4J7E6 ZV1X3Y4L10U4文档编码:CK10G10B4R1M1 HN7H5Y4J7E6 ZV1X3Y4L10U4文档编码:CK10G10B4R1M1 HN7H5Y4J7E6 ZV1X3Y4L10U4文档编码:CK10G10B4R1M1 H

22、合成整体。(2)面层空鼓、有裂缝:由于铺细石混凝土之前基层不干净,如有水泥浆皮及油污,或刷水泥浆结合层时面积过大用扫帚扫、甩将等都易导致面层空鼓。由于混凝土得坍落度过大滚压后面层水分过多,撒干拌合料后终凝前尚未完成抹压工序,造成面层结构不紧密易开裂。(3)面层抹纹多,不光:主要原因就是铁抹子抹压遍数不够或交活太早,最后一遍抹压时应抹压均匀,将抹纹压平压光。六、质量记录本工艺标准应具备以下质量记录:(1)水泥出厂合格证及复试记录单。(2)现浇混凝土试块试压记录。(3)地面面层分项工程质量验评记录表。项目(专业)技术负责人交底人接受交底人文档编码:CK10G10B4R1M1 HN7H5Y4J7E6
