碾压混凝土（Roller Compacted Concrete，简称RCC）是一种通过振动压路机进行密实成型的高密度混凝土材料。其核心特点是干硬性混凝土拌合物的低水灰比与高骨料占比，结合机械化连续摊铺工艺，适用于大体积、高强度需求的工程场景。
从材料组成来看，RCC通常采用普通硅酸盐水泥、粗骨料（如碎石）、细骨料（砂）及少量掺合料（如粉煤灰）混合而成。其配合比设计需满足碾压后的密实度要求，同时兼顾抗压强度和耐久性。美国混凝土协会（ACI）在《ACI 327报告》中详细规范了RCC的材料配比标准。
施工工艺方面，RCC采用分层摊铺、振动碾压的快速施工法。每层厚度通常控制在20-30厘米，通过10-15吨级振动压路机进行6-8遍碾压，形成致密结构。这种工艺使施工效率较传统混凝土提高50%以上，特别适合大型水利枢纽工程，例如中国三峡工程三期围堰曾使用RCC技术实现日均浇筑强度1.5万立方米。
主要应用领域包括：
根据中国建筑科学研究院的实验数据，RCC的28天抗压强度可达30-40MPa，渗透系数可控制在10⁻⁹cm/s量级，展现出优异的力学性能和防渗能力。但需注意，RCC对基层平整度要求较高，且不适用于需要复杂表面处理的装饰性工程。
碾压混凝土（Roller Compacted Concrete，简称RCC）是一种通过振动碾压工艺实现密实的干硬性混凝土材料。以下为详细解释：
定义与特性
RCC采用低水泥用量（通常为普通混凝土的30%-60%）和低水灰比，形成超干硬性拌合物。其强度来源于机械振动碾压而非传统振捣工艺，具有施工速度快、成本低、抗压强度高的特点。
材料组成
主要成分包括：硅酸盐水泥、火山灰质掺合料（如粉煤灰）、砂、分级粗骨料、水及减水剂等外加剂。粗骨料粒径需严格分级以保证碾压密实性。
施工工艺
采用“薄层连续铺筑+振动碾压”流程：
典型应用
广泛应用于大坝（如RCC重力坝）、高速公路基层、港口堆场、机场跑道等需要高承载力和耐久性的工程。例如三峡工程三期围堰采用RCC技术，日浇筑强度达1.9万m³。
注：更多专业参数（如配合比设计、温控措施）可参考水利行业规范《碾压混凝土坝设计规范》（SL 314-2018）。
