新泽西护栏滑模混凝土配合比设计和应用探索
|
摘要
基于新泽西护栏滑模混凝土工作性出发,文中以水灰比、砂率和细集料细度模数为因素,采用正交设计方法设计护栏混凝土C30初选配合比,分析了水灰比、砂率和细度模数对中央分隔带护栏C30混凝土现场摊铺作业工作性能和力学性能的影响,所设计C30混凝土成功应用于广东省龙怀高速公路路面7标工程建设中,为进一步推广现代化高速公路附属工程滑模摊铺施工提供工程借鉴。
Based on the workability of Sliding Concrete for New Jersey Railing, this paper takes the water-cement ratio,sand ratio and fine aggregate fineness modulus as the factors, and uses the orthogonal design method to obtain the C30 primary mix ratio of the guardrail concrete. Finally, the sand ratio is analyzed on the slipform paving construction. The effect of fineness modulus on the performance and mechanical properties of the C30 concrete paving operation in the central separation belt of the expressway was successfully applied in the LM7 standard project of Longhuai Expressway.It can be used to provide the practical engineering for further promoting modern slipform paving construction.
