Spread 23mm metal aggregate wear-resistant surface after the strength reaching the standard, being troweled as same time with placing. Steel formwork would be used, and special attention should be paid to the slope direction when perform the work.5.1.2施工时间：混凝土初凝时开始进行，直至表面收光完成；Construction time: start when concrete become pre-hardening, and end after surface leveling. 5.1.3施工设备：采用专门的抹光机进行机械镘抹作业；Equipment: use specialized trowelling machine to do the operation. 5.1.4表面提浆：撒布材料前应使用圆盘机械镘抹，均匀地将混凝土表面提浆，去除多余浮浆；Surface mud extracting: use disk-type trowel to evenly smooth the concrete surface prior to spread the materials, so as to remove the excess laitance;5.1.5耐磨料施工：耐磨材料撒布的时机随气候、温度、混凝土配合比等因素而变化。撒布过早会使耐磨材料沉入混凝土中而失去效果；撒布太晚混凝土已凝固，会失去粘结力，使耐磨材料无法与其结合而造成剥离。判别耐磨材料撒布时间的方法是脚踩在砼上，约下沉58mm时，即可开始第一次撒布施工。Wear resistant material construction: the time to spread this kind of materials varies with the climate, temperature, mixture ratio of concrete and other factors. Spreading too early would make wear-resistant materials sink into the concrete and lose effect; if spreading too late, concrete has already solidified, so it will lose the cohesive force, which will lead to stripping because the 2 kinds of materials cant be combined properly. The method to determine the time to spread the materials is that put feet on the concrete, if sink 58mm, can start the first spreading construction.第一次撒布作业，将规定用量三分之二的耐磨料均匀撒布在初凝的混凝土表面上；The 1st time spreading operation: 2/3 wear resistant material should be evenly distributed on the concrete surface with initial setting;待耐磨料吸收一定水分变黑后，用6米长的铝合金（或50100钢质方管）擀枋对表面进行擀平，After the materials absorb certain moisture and getting dark, use 6m long aluminum alloy (or 50 x 100 steel tube) roller to make the surface flat.表面擀平后，用圆盘机械进行镘抹作业，然后再用擀枋擀平，After the surface is smooth, use disc-type disk-type trowel, then roller to make it flat.以上工序完成后，第一层材料硬化至一定程度时（在25C时约4560min）进行第二次撒布作业；将剩余的40%硬化剂撒在第一层上，再次重复以上和工序。After the above steps are completed, start the 2nd time spreading operation when the first layer of materials is hardened to a certain degree (about 4560min at 25 C); cast the remaining 40% hardening agent on the first layer, then repeat the step and .第二次的搓抹作业，共需进行至少三次圆盘机作业；在此过程中，可以再用铝合金擀枋适时刮平，将多于的水泥浆及时清走，不足的地方补平。这一道工序也是关乎地面平整度的关键工序。2nd time rubbing operation: a total of at least three times of disc machine operation should be performed; in the process, timely use aluminum alloy roller to smooth, remove the extra cement slurry and fill the insufficient places. This step is the key process related to floor flatness. 表面收光：待圆盘机械搓抹作业完成后，经目测观察和水平仪随机测量，平整度满足要求后，即可用机械抹光片（卸下圆盘）进行镘抹，磨光机的运转速度和磨光刀片的角度视耐磨料的硬化情况而适时调整。机械镘抹作业应纵横交错进行，至表面收光为止，边角可用手工镘抹完成。机械磨光的次数一般反复34次，即可达到要求。Surface finishing: after disc-type trowel operation is completed, and visual inspection and random measurement with level gauge, then use mechanical troweling tablets (unload the disc) to smooth, timely make adjustment to the operation speed of polishing machine and the angle of polishing blade.Disc-type trowel operation should be arranged in a crisscross way up to the surface finishing, and to the corner, complete with manual. Mechanical polishing times generally repeat 34 times, to meet the requirements.这是最后一道工序，是地面光洁度和感官的关键工序。This is the last step, which is the key procedure to floor surface finish and sensory.5.1.6施工中的注意事项Matters needing attention in construction 1、混凝土初凝过程中，施工的脚印必须补填含骨料多的砼；The footprints occur in the period of the initial set of concrete must fill with aggregate concrete;2、切实掌握好收光时耐磨料硬化的程度，时间太晚，收光面观感达不到要求；To master the hardening degree of wear-resistant material when the surface finishing, otherwise, the finishing surface does cant meet the requirement if the time is too late. 3、无论在任何时候，严禁向耐磨料里洒生水。否则会影响耐磨地面的表面硬度及耐磨强度；Forbid to sprinkle raw water on the wear- resistant material at any time, because it will affect the surface hardness and abrasive resistance.4、如夜间施工时，要保障照明，以确保收光效果；The lighting should be guaranteed when work at nights to ensure the finishing effect. 5、最后的收光作业阶段，施工人员应穿防水塑料纸包裹的泡沫平底鞋。At the last light finishing operation stage, the workers should wear foam flat shoes wrapped with waterproof plastic paper.6、后浇带处的耐磨地面施工。为保证整体质量，此处的耐磨地面施工还须认真、仔细的施工，对后浇带两边接口处需细细的人工镘抹，力求和大面积地面接顺，形成一个一致的整体。Wear-resistant floor construction for post-cast strip: in order to ensure the overall quality, wear-resistant floor construction must be performed seriously and carefully. As to the connection points at the both sides, arrange worker to trowel slowly, striving to joint smoothly with large-area floor to form a coherent whole.7、地坪砼浇灌时注意保持坡道及平整性，并留设试块，完工24小时后及时切缝处理；Pay attention to maintain the slope and its levelness when concrete casting for floor, and reserve the testing pieces, timely make joint-cutting treatment 24 hours after finished.8、按设计规定留置拉杆钢筋及传力杆钢筋，栏杆筋为14900，L=700mm；传力杆钢筋为20270，L=400；留置的钢筋头注意保护以免伤人；Indwell tie bar and dowel steel according to the design requirements, with tie bar: 14900, L=700mm and dowel tie bar 20270, L=400, be careful to not hurt people. 5.1.7耐磨地面的养护curing of wear-resistant floor 耐磨地坪施工5-6小时后，表面铺薄膜养护，24小时内禁止非施工人员在上面行走，地面养护3天后可进行后续项目的施工。After wear-resistant floor construction is completed in 5-6 hours, cure it with thick film on surface. Workers are forbidden to walk on it in 24 hours, and the follow-up step can be continued after curing the floor for 3 days. 5.1.8耐磨地面的保护 protection of wear-resistant floor 仓库上部为钢结构，因此耐磨地面完成后，对其保护是本工程的重点和难点之一。The steel is located above the warehouse, so protection of wear-resistant floor is key and difficult point in this project. 具体的保护方案如下detail:1、地面完成后的第三天，在地面上满铺塑料布覆盖，并浇水湿润，塑料布的边角用重物压牢。At the 3rd days after the completion of the floor, cover it with plastic cover and spray the water, and press firmly with heavy objects at the edges of plastic cloth. 2、严禁将其他材料的包装纸箱放在地面完成区域，由于包装纸箱被水湿润后脱落的有颜液体更易污染耐磨地面。Strictly prohibit putting package boxes for other materials on the completed area, because the color of the boxes after wetted by water is more susceptible to contaminate the floor.3、对于有防火墙的两边地面，应尽量选择规矩的模板保护，减少后续的墙体施工对地面的污染。The ground with firewall at both sides, should try to choose standard formwork to protect, further to reduce the contamination on floor by follow-up wall construction.5.2不发火水泥砂浆地坪 non-sparking floor mortar leveling5.2.1不发火水泥砂浆地坪材料：20mm厚1:2.5水泥砂浆抹平（骨料用石灰石、白云石砂、NFJ金属骨料）Materials: 20mm 1:2.5cement mortar leveling (aggregate: limestone, dolomite sand,and NFJ Metal aggregate).5.2.2施工前表面清理干净，刷素水泥浆一道，内掺建筑胶；Clean the surface before construction, paint neat cement paste for one time, mixed th construction glue. 6.质量控制措施 Quality control measures6.1质量控制操作严格按照各规范要求执行；the operation of quality control should proceed strictly aside by all specifications 6.2建立健全的质量保证体系，责任落实到人。Establish a complete quality control system with distribution responsibility system to individuals. 6.3组织内部各岗位质量工作职责如下：Organization internal quality control responsibility:项目经理：是本工程管理者，也是第一质量责任人，对工程质量、工程成本、工程进度全面负责，保证每个过程都在受控状态下进行，确保产品质量符合规范、满足合同规定的要求。Project Manager: PM is the administrator of the project as well as the first quality responsible person.
