摘要

输水隧洞衬砌作为薄壁强约束结构，其混凝土在早龄期易因收缩开裂而影响耐久性。传统矿物掺合料的掺入虽可一定程度降低收缩变形，但会延缓早期强度发展，无法有效改善混凝土抗裂性能。本研究引入超细矿粉重构胶凝材料体系，调控胶凝材料的组成与级配，探究其对混凝土工作性能、力学性能和抗裂性能的影响。试验结果表明，相较于对照组（单掺15%粉煤灰，FA15），经过优化后的混凝土（掺入10%超细矿粉SL₂和10%粉煤灰，SL210FA10）3d抗压强度提高6.9%，劈裂抗拉强度提高18.0%；干燥收缩7d后有所下降，开裂风险系数下降9%以上；微观机理分析表明，超细矿粉的物理填充作用优化了颗粒堆积，液膜厚度下降6.3%，物理填充作用和火山灰活性共同促进了微观结构致密化，使界面过渡区厚度降低20%，微观弹性模量提高33%，抗裂性能显著改善。本研究通过掺入超细矿粉实现了混凝土早期强度和抗裂性能的同步提升，为输水隧洞工程实践提供了理论依据和技术支持。

Abstract

The lining of hydraulic tunnels is a thin-walled, strongly constrained structure and its concrete is prone to shrinkage cracking at early age, which affects its durability. Although the incorporation of traditional mineral admixtures can reduce shrinkage deformation, it delays the development of early strength and cannot effectively improve the crack resistance of concrete. In this study, ultrafine mineral powder was introduced to optimize the composition and particle gradation of cementitious materials, and its effects on the paste's working performance, as well as concrete's mechanical properties and crack resistance, were investigated. The test results show that the 3-d compressive strength of concrete increases by 6.9%, and the splitting tensile strength increases by 18.0%. After 7 days of drying, the risk coefficient of cracking decreased by more than 9 %, the thickness of liquid film decreased by 6.3%, the thickness of interfacial transition zone decreased by 30%, the microscopic elastic modulus increased by 10%, and the crack resistance was significantly improved. In this study, the early strength and crack resistance of concrete were improved simultaneously by optimizing the physical filling effect and activity regulation of cementitious materials, which provided theoretical bases and technical support for the engineering practice of hydraulic tunnels.

Key words： water conveyance tunnel; lining concrete; ultra-fine slag; crack resistance; particle gradation
