he distance of 300cm. 2.測試方法及標準 Test method - 使用設備: FloorPro 或 FMeter Equipment used: FloorPro or FMeter - 測試時間: 地坪拋光結束后 24 小時內 Test time requirement: the floor must be test within 72 hours after floor installation. - 提供測試結果資料。 Trowlling with double pan machine for more than twice to consolidate the concrete and improve the wearness of the floor surface, but remember to avoid over trowlling. Whenever it es to trowlling , the blade should dip a little to strengthen the frictional force of the concrete surface. Dip more to the right side than last time when trowlling. 四、平整度測試 Flatness test 1. F 數(shù)的定義 Definition of FNumbers - F 數(shù)是美國混凝土協(xié)會和加拿大標準協(xié)會針對混凝土地坪平整度和水平度數(shù)值和測量方法所做的規(guī)定。 使用手動式整平器 (Highway straight edge)進行二次整平 Use Highway straight edge to screed the concrete for a second time. 三、混凝土表面打磨和拋光: Concrete trowel and finish 為了混凝土表面平滑,使用優(yōu)秀的施工人員及設備; Use excellent technicians and advanced equipments to attain the flattest surface of the floor. 為了確保平整度,使用激光整平機或同等級設備及手動式整平器; Use copperhead or machines of the same grade and Highway straight edge. 確?;炷恋钠焚|,必須使用乘坐式的圓盤為 92 英寸的大型打磨機進行打磨;使用雙圓盤拋光機進行拋光,為了達到壓實混凝土,提高混凝土表面的耐磨性,使用重量 500kg 以上的電動打磨機磨光為原則;使用圓盤研磨后必須再使用刀片拋光; To ensure the quality of the concrete, you have to use rideon trowels with 92 inch floating pan to work on it. In order to consolidate the concrete and improve the wearness of the floor surface, double floating pan is preferable and 500kg + electrical floating finisher is a must. Use blade to polish the concrete after abrasion.; 混凝土大部分使用機械研磨,柱子周邊 及邊角區(qū)域的磨光用手工仔細進行; Most construction area can be toweled by power trowel machine, areas around column or corners should be trowel by hand carefully. 現(xiàn)場管理人員具備熟知有關混凝土的專業(yè)術語及進
