Construction Method Statement for Concrete Masonry Wall. 砼砌体施工方法 Site Preparation 施工准备 All working areas approximately 4m wide, adjacent to the wall should be level and clean. 工作面积需约4m宽，与墙体相邻的地方需干净和平整。 All facing CMU`s should be selected at random from several pallets (CMU Cubes) and re-stacked neatly in small plies within easy reach of the Mason constructing the wall. 所有劈裂砌块砌筑时，必须从几包砌块中随机选取，砌块需整齐地就近堆放。 Working areas should be kept clean so as not to damage or contaminate blocks, this also makes for a safe working area. 工作区需保持清洁并避免损坏砌块。 Setting out for CMU wall 开始施工 From construction drawings mark on to the foundation using masons pencil or crayon and tape measure, all window, door openings and control joints. Measure between corners and door openings or control joints, calculate the number of CMU`s (390mm + 10mm =400mm) adjust mortar joints slightly to fit CMU`s to the nearest ? block. Mark on the foundation CMU and mortar joint. Where there are masonry columns between, and masonry above windows, while setting out make allowance to align vertical mortar joints in masonry below and above windows. 根据图纸将所有门、窗及控制缝的位置都用铅笔在基础梁上做好记号，计算墙角到门、窗洞口间的砌块模数(400mm)，通过灰缝宽度调整，尽可能将模数调至砌块模数的1/2，并在基础上标出砂浆灰缝的位置。 窗间墙的上方墙体和下方墙体的灰缝需对齐。 Check position of all vertical rebar dowels, to ensure hollows within blocks align with steel dowels. 核查预埋插筋的位置，确定插筋间距。 Mortar 砂浆 砂浆采用地产砂与海螺水泥（经试验做出的配合比）搅拌而成。 Mortar should be mixed with clean water. 需采用自来水搅拌砂浆。 Mixer should be clean prior to mixing mortar. 搅拌前需清洁搅拌机。 To obtain good workability and other desirable properties of plastic color consistent masonry mortar, the ingredients must be thoroughly mixed. After all materials are batched in to mixer, they should be mixed from 3 to 5 minutes. Less mixing time may result in nonuniformity, poor workability, low water retention, and less than optimum air content. Longer mixing times may effect strength of mortar. 为使砂浆使用性能良好，砂浆成份需被彻底搅拌。 材料倒入搅拌机后，需搅拌3~5分钟。如搅拌时间过短，则砂浆会出现不均匀，工作能力差，水
