应用市场 特性和优点 产品
在大多数应用环境中,合理的混凝土配合比设计,使用高品
质的产品是持久耐用的混凝土的关键。ACI指导手册的最佳
实践经验结合西卡在全球逾百年的混凝土解决方案的专业
技术,西卡能够为您建筑项目提供一系列合适的产品,创造
更耐久,阻裂的和有成本效益的混凝土板。
业主、承建商,类似制造商,西卡整体混凝土地坪解决方案
涉及到建筑的所有阶段,从准备,到浇筑,到产品,西卡能够
为各种规模的工厂建设创造价值。去除传统的加固方案和尽
可能减少切缝设置使工地安全最大化。西卡在土承或桩承基
础的实践经验表明,钢纤维混凝土可以部分或全部替换钢筋
应用在工业厂房首层地坪,依据TR34,充分考虑将来地面承
受的荷载情况进行验算,可以增加设缝间距或减少裂缝产生
的可能。正确选择产品和优化设计实现了成本节约。
项目团队通常自己会设计混凝土板的配合比。如果能获得
所有必要信息,西卡可以协助您的设计团队调整混凝土水
灰比,优化浇筑性能,减少收缩,提升板结构负载能力,减
少翘边。
通过接受标准细则、相关注意事项和设计优化,达到节省建
设成本和减少工期的目的。

地坪专用混凝土配合比设计
混凝土配合比设计基础是合理的水泥、水和骨料,通过化学
外加剂和矿物掺合料优化性能。西卡首款混凝土外加剂可追
溯到1910年,毋庸置疑的是西卡是世界上最大的和最得信赖
的混凝土产品制造商。
地坪混凝土不同于普通浇筑混凝土,它的显著特征包括浇
筑时的工作性和包裹性,凝结时间和均匀性,可塑性,混凝
土硬化后的收缩率以及生产和运输的经济性。应该相应地
选择原材料和比例。除了满足规定的抗压强度外,为了获得
良好的易修整性,应使用充足的水泥含量和其他胶结物(如
使用)。
某汽车工厂项目,混凝土拌合物状态良好,
无泌水等明显可见缺陷,但是配合比中水
泥含量偏少,掺入大量矿渣粉,由于受当地
原材料供应限制,选用的人工砂泥粉、石粉
含量过高,又没有通过匹配的外加剂产品调
整配合比,未到正常凝结时间,混凝土表面
结皮严重,造成“假凝”现象。承包商通过
洒水提浆后施工硬化剂,结果造成大量局
部开裂、空鼓问题。
西卡对适合地坪使用的混凝土配合比设计有以下几个建议:
水泥:P•O硅酸盐水泥(或胶凝材料总量)建议掺量应
≥350kg/m3
;
硬化地坪施工用混凝土,粉煤灰掺量不超过5%,不得
掺矿粉;
水灰比:不大于0.5;
砂子:中砂,首选天然砂;
石子:连续级配,利用实际最大整体混合骨料粒径,其
最大粒径不应大于面层厚度的2/3;
自卸混凝土塌落度宜控制在约140mm,泵送混凝土塌落度
宜控制在约160mm,钢纤维混凝土可适当放大10-20 mm;
混凝土气体含量〈3%;
西卡地坪专用外加剂:减少收缩,减少用水量,改善和
易性。
原浆抹光混凝土对粉煤灰和矿粉掺量没有特别限制,但是
必须有良好的合易性和易修整性,使混凝土地面符合面层
材料,例如环氧、聚氨酯等施工的要求。
如配制钢纤维混凝土,西卡基于欧洲标准EN 206、EUROCODE2-part1法规和英国“混凝土协会”关于混凝土建筑地
面的技术报告TR34,严格遵循Loosberg、Meyerhof和Hetenyi的方法,充分考虑地坪混凝土板在未来投入运营将要面
临的承载要求进行安全验算。
混凝土配合比设计的成分:石子、水、水泥、高性能外加剂、砂子(从左至右)

西卡地坪专用混凝土外加剂
混凝土外加剂是液体或粉末的,在拌合过程少量掺入混凝
土,用量通常根据水泥(或胶凝材料)含量而定。
混凝土外加剂对新拌混凝土和/或硬化混凝土性能有非常大
的影响。外加剂起到化学和/或物理作用。
地坪混凝土常用的外加剂,依据GB50119-2013分类,
Sika® Viscocrete®——减水剂
减水剂的使用能提升整体强度,降人低渗透性,便于浇
筑,控制塌落度,优化终饰面性能。
Sika® control——减缩剂
减缩剂(SRA)或收缩补偿外加剂(SRCA)用于控制混
凝土早期收缩裂纹。从混凝土浇筑开始就减少裂纹发生
概率,继而延长寿命,减少维护成本。
SikaPump®——泵送剂
改善新拌混凝土稳定性,更容易泵送,特别是针对颗粒
形状不好,不符合分布曲线的骨料。
Sika® Retarder——缓凝剂
延长初凝凝结,扩大施工时间和延迟发展早期强度
西卡地坪专用外加剂在钢纤维混凝土中的应用
良好流动性(塌落度和扩展度)
易施工
无泌水、浮浆
控制混凝土均匀性
无露头钢纤维
获得高平整度
西卡地坪混凝土专用外加剂技术符合当前地坪混凝土低收
缩、易施工等要求的趋势。这种趋势需要新的、专业的地
坪外加剂技术。西卡地坪专用外加剂的应用给地坪混凝土
配合比设计带来多个技术创新。一个主要特点是极大地减
少混凝土用水量。获得更低W/C,显著降低混凝土渗透性,
进而提升耐久性。减少地坪混凝土的收缩是另一个特点,
从而达到控制裂纹的目的。

西卡地坪混凝土纤维技术
纤维是混凝土和砂浆理想的构成要素。纤维能很好地改善这类
材料的固有缺陷。通常对能量吸收和防火性能有所提升。同时
减少收缩裂纹形成和裂缝扩展。纤维增强混凝土相比传统钢筋
混凝土显著减少钢筋用量,但仍非常耐用,甚至更好。
纤维在建筑材料中使用历史悠久,比一些现代技术更实
用。混凝土发展已有相当长的时间了,纤维技术也随着不
断更新。纤维增强混凝土不断扩展,钢纤维可以部分或全
部替换钢筋在地坪混凝土中的应用。SikaFiber® 技术一致走
在前沿。
依据不同功能需求,不同类型的纤维被用到混凝土和砂浆。
短的,细小的合成纤维用于防火和减少裂纹的需求,同时长
的合成纤维或钢纤维普遍提升能量吸收能力。特殊需求需要
特殊纤维材料和形状。例如西卡地坪专用混凝土使用两端弯
钩形状的钢纤维达到控裂增强的目的。西卡提供其他各种类
型和混合的钢纤维。

结构作用
混凝土通常有良好的受压能力,较弱的抗拉能力。如果混凝
土由于高弯曲应力作用断裂,又没有增强,系统毫无征兆地
就倒塌。同传统钢筋增强一样,使用合适的纤维也有传递和
分散作用。裂纹桥接的纤维不仅提升抗裂性能同时阻止裂纹
扩大。纤维在裂纹两端紧密锚固,起到架桥作用,有效地“
缝合”裂缝,阻止其扩大。纤维增强混凝土,因此,提升延
展性,能够在发生挠曲部位吸收能量。
裂纹分散
以水泥为胶结物的硬化体收缩常常是导致混凝土裂纹的发生
原因。这些裂纹肉眼可见,并且存在一定的危害。通过植入
纤维,应力方向被转移并耗散,通过形成微裂纹而阻止宏观
裂纹形成。微裂纹不会显著地降低强度,提升表面效果并允
许自动修复。因此,纤维的使用有益于提高耐久性

接缝密封与保护
混凝土随着干燥收缩或温度变化发生膨胀与收缩。为了
控制裂缝的产生,混凝土板会按预设间距设置裂缝。这
些接缝可能是锯切的(缩缝)或者预留的(隔离缝或伸
缩缝),允许混凝土随着周围环境变化发生体积变化。
即使混凝土接缝用来保护不受控制的裂缝发生,它们自
己也要被保护。负载叉车会很快损坏接缝边缘,导致接
缝变宽并变得不安全。为了保护这些接缝,使用环氧或
聚氨酯填充使其平顺。地坪板的伸缩缝也应承受负载叉
车冲击,但是要允许接缝运动。
6 Sika® SLAB SOLUTIONS
Comprehensive Approach To Slabs On Ground
Concrete expands and contracts with drying
shrinkage and temperature changes. To control
where this cracking occurs, joints are placed into
the concrete slab at a predetermined spacing.
These joints can be saw cut (control) or preformed
(isolation / expansion), allowing for these natural
changes in the concrete throughout varying
ambient conditions.
While concrete joints offer protection from
uncontrolled cracking, they need protection
themselves. Heavy forklift traffic can quickly
damage joint edges causing them to widen and
become unsafe. To prevent joint damage, joints
are filled with either an epoxy or polyurea control
joint filler and shaved smooth to create a flush
profile for forklift traffic. Expansion joints in floors
should still be able to withstand heavy traffic but
have the flexibility for greater joint movement.

西卡是国内唯一一家从设计到施工,再到验收,都可以提供一站式服务的材料供应商。客户对混凝土地面的普遍要求是
平整、不开裂、经久耐用。这一点正是西卡致力于并不断探索前进的方向。我们非常重视客户的体验。西卡充分发挥自
身的产品和技术优势,给客户带来最佳的体验。
地面必须控制表面的起伏,将其与理论完美平面的偏差限制
在合乎地坪规划用途的范围内。
平整度(FF)和水平度(FL)是表征地坪表面起伏状态的两
个重要指标,ACI117提出了使用F-数字系统通过测量600mm
上的坡度变化值来评估地坪表面的平整值,通过在3m距离的
两点之间测量对于水平平面而言的提升值的变化来测量地坪
表面的水平度。合格的的FF值和FL值能确保整个建筑包括其
所有静态设施和MHE都能可靠的运作。
由于楼板的挠度以及地基、桩基和其它支承结构的沉降都会
对表面规整度产生很大的影响。ACI17要求对地坪表面的评估
制定默认的72小时内进行,以避免验收程度上出现任何可能
的争端,并提醒承包商在接下来的工作中改良施工技术,符
合以便使工序要求。
