scc(Self-Compacting Concrete)称为自充填混凝土:免振动捣实,即由自身重力穿越钢筋间隙,能充填於模板各角落之混凝土。
作用
自充填混凝土主要着重在新拌混凝土(Fresh Concrete)阶段流动性与模板充填能力之要求,而对于其硬固后之物理性质或力学性质并无直接关联,然而使用自充填混凝土的精神,主要即在于以改良混凝土的物理性质(流动性/模板充填能力),来达到确保钢筋混凝土构造物质量与可靠度的目的,同时藉由良好而确实的模板填充,更可提高钢筋混凝土构造物整体的耐久性与强度,至于混凝土应具有的抗压强度,则仍依结构设计需要而定。而就施工上而言,自充填混凝土施工特性上亦可有效改善劳工工作环境、降低施工处噪音、增进营建工程效率、解决特殊工程难题。2100433B
