大掺量矿物掺合料高性能混凝土在京沪高铁四标段中的应用

Applied research on high performance concrete with high-volume supplemementary cementitious materials in No.4 Bid of the Beijing-Shanghai high speed railway

以京沪高速铁路为工程背景,试验研究了矿物掺合料(粉煤灰、粉煤灰-矿粉)对混凝土工作性能、力学性能和耐久性能的影响以及大掺量矿物掺合料高性能混凝土的配制技术。结合实际工程,介绍了大掺量矿物掺合料高性能混凝土原材料选择、配合比设计、施工工艺等方面的控制技术。

Based on engineering practice in Beijing-Shanghai high speed railway, effect to concrete workability, meachincal performance, and durability of mineral admixtures are studied, at the same time the preparing technology of high performance concrete with high-volume supplemementary cementitious materials are studied. Combining with pracitce engineering, control technology of raw materials, design of mixing proporation and construction for high performance concrete with high-volume supplemementary cementitious materials are introduced.
