基层混凝土初凝时（约3～4h)，即可进行耐磨地坪施工，先在抹光机上安装圆盘，整体打磨混凝土并从周边逐渐向内收抹，起到平整和提浆作用，平整度偏差控制在2m范围内不超过3mm。

（ 2)**次铺撒金刚砂硬化剂的时间须严格控制，铺撒过早会使金刚砂沉人混凝土，影响表面强度；铺撒太迟，混凝土已经凝固，不能与混凝土粘结而起不到应有的效果，一般在脚踩下陷不超过5mm时开始铺撒**次。墙柱及靠近门、模板边等部位的混凝土失水较快，应先铺撒。

（ 3)**次将2/3金刚砂硬化剂材料均匀撒布在混凝土表面（不均匀处用刮板刮匀)；待材料吸收混凝土中的水分、表面出现返潮颜色变灰暗后，即开始**次抹平。采用装圆盘的抹光机碾磨分散，使其与基层混凝土浆结合在一起，注意不要搓抹过度。

（ 4)随即将余下的1/3料均匀撒布在混凝土表面，撒铺方向与**次垂直，进行第二次抹平工作，**用装刀片的抹光机完成抹光工作。注意随混凝土凝固时间调整刀片倾斜角度（转速及角度视硬化情况调整)，抹光机作业时应纵横交错（3次以上)进行。边角部位可采用人工钢抹子抹光。

（ 5)耐磨地坪混凝土终凝后即开始养护，在太阳直射处可用专用养护剂，在地下室等阳光照射不到处可浇水养护，养护时间7d以上。

（ 6)抹光机抹光后，面层若有抹纹可用钢抹子进行有序同向的人工压光。

（ 7)耐磨地坪完成24h内即可拆边模，拆模后边缘不齐处可用切割机切齐。

6、切缝

硬化剂地面施工完成 7d后，按结构设计要求锯切收缩缝（类似于混凝土路面切缝)，缝深20mm左右。对混凝土框架结构，可按柱网尺寸切缝，亦可按业主意图切缝，填缝材料可采用沥青、硅胶等。

7、修补作法：若硬化剂地面损坏，可采用两种方式修补。

（ 1)局部破损可用丁苯乳胶加水拌和筛除骨料的硬化剂材料配制的胶泥刮腻子修补。将破损区清理干净，充分浸水润湿，再用丁苯乳胶加水乳液进行涂刷。

（ 2)较大面积破损可根据需要画线锯切，凿掉面层及部分基层混凝土，再清理润湿，扫素水泥浆，浇捣混凝土，**施工硬化剂面层。

8、注意事项及质量验收

（ 1)外观质量及表面平整度应符合建筑地面工程施工质量验收规范中外观质量的验收标准。由于磨光后的地坪表面非常光滑，车库的行车道部位须做橡胶（或其他材料)止滑坎。

（ 2)抗冲击性能检查：对龄期28d的混凝土采用重2250g钢球，分别从1m、2m高处自由落下冲击耐磨地面。坠落高度为1m时，凹坑直径应小于或等于12.0mm，深度小于或等于0.30mm；坠落高度为2m时，凹坑直径应小于或等于14.0mm，深度小于或等于0.50mm；地面硬度应符合要求。
Grassroots initial setting of concrete (about 3 ~ 4h), wear-resistant floor construction can be carried out, first install the disk in the trowel, overall polished concrete and gradually wipe inward from the periphery, to play the role of smooth and mention pulp, flatness deviation is controlled within a range of no more than 2m 3mm.

     (2) Spreading first time carborundum hardening agent shall be strictly controlled, Spreading prematurely sank emery make concrete impact surface strength; Spreading too late, the concrete has solidified, can not bond with concrete and will not achieve the desired effect, usually in the foot began to sag no more than 5mm Spreading the first time. Qiang Zhu and close the door, templates and other parts of the concrete edge faster water loss, should Xianpu Caesar.

     (3) The first 2/3 emery hardener material spreading evenly in the concrete surface (uneven scraping with a scraper at uniform); to be material to absorb moisture from the concrete surface after the damp dark color change, which began first times smooth. Use mounted disk trowel milled dispersion to bind together grassroots concrete mortar, be careful not to rub the wipe over.

     (4) Then the remaining 1/3 of the material evenly spreading the concrete surface, sprinkle the shop with the first vertical direction, a second smooth work, and finally loaded blade trowel trowel work completed. Note that with the concrete sets time to adjust the tilt angle of the blade (hardening of the case, as the speed and angle adjustment), trowel work should be criss-crossing (more than 3 times) were. Corner parts used in artificial steel trowel trowel.

     (5) wear-resistant floor and then began a final setting of concrete curing, curing agent available special place in direct sunlight, the sunlight in the basement is not available everywhere water conservation, conservation over time 7d.

     (6) After trowel trowel, wipe the surface layer of grain is available if ordered with steel trowel pressure to artificial light.

     (7) The wear-resistant flooring can be completed within 24h demolition side mode, available at Chaimo after missing the edge trimming cutter.

    6, slit

     Hardener ground after construction is completed 7d, according to the structural design requirements sawing contraction joints (similar to concrete pavement slit), deep seam about 20mm. Concrete frame structure, according to the column grid size slit, also according to the owners intent kerf, caulking material can be asphalt, silica gel.

    7, repair practices: If hardener ground damage, can be used two ways to repair.

     (1) local damage available styrene-butadiene latex mixing with water sieve materials other aggregate hardener formulated mastic putty repair. The damaged area clean, fully soaking wet, and then adding an aqueous emulsion styrene-butadiene latex for brushing.

     (2) a large area damaged may need to draw a line cutting, cutting off part of the surface layer and the base layer of concrete, and then clean up wet, sweeping mud plain water, pouring concrete, final construction hardener surface.

    8 Notes and quality acceptance

     (1) the appearance of quality and surface flatness should be consistent with the building ground for acceptance of construction quality in appearance quality acceptance criteria. Since the floor after a very smooth surface finish, lane portion of the garage to be done rubber (or other material) slip Hom.

     (2) impact resistance examination: age of concrete using heavy 2250g steel ball 28d, respectively, from 1m, 2m height of free fall impact wear-resistant surface. When the fall height 1m, pit diameter should be less than or equal to 12.0mm, depth is less than or equal to 0.30mm; falling height when 2m, the pit diameter should be less than or equal to 14.0mm, depth is less than or equal to 0.50mm; surface hardness should comply Claim.
