Abstract

This study aims to address the issues posed by frost damage to concrete structures in cold regions, focusing on reinforcement and repair methods to increase the service life of existing structures instead of costly reconstruction solutions. Due to the limitations of conventional concrete in terms of durability and strength, this research focused on ultra-high-performance concrete (UHPC) by replacing part of the cement with recycled brick powder (RBP) to strengthen ordinary C50 concrete, obtaining UHPC-NC specimens. Mechanical tests investigated the bonding performance of UHPC-NC specimens under various conditions, including interface agents, surface roughness treatments, and freeze-thaw after 0, 50, 100, and 150 cycles with a 30% replacement rate of RBP. Additionally, a multi-factor calculation formula for interface bonding strength was established according to the test data, and the bonding mechanism and model were analyzed through an SEM test. The results indicate that the interface bonding of UHPC-NC specimens decreased during salt freezing compared to hydro-freezing, causing more severe damage. However, the relative index of splitting tensile strength for cement paste specimens showed increases of 14.01% and 14.97%, respectively, compared to specimens without an interface agent. Using an interface agent improved bonding strength and cohesiveness. The UHPC-NC bonding model without an interfacial agent can be characterized using a three-zone model. After applying an interfacial agent, the model can be characterized by a three-zone, three-layer bonding model. Overall, the RBP-UHPC-reinforced C50 for damaged concrete showed excellent interfacial bonding and frost resistance performance.

摘要

本研究旨在解决寒冷地区混凝土结构冻害所带来的问题，重点关注加固和修复方法，以延长现有结构的使用寿命，而非采用成本高昂的重建方案。由于传统混凝土在耐久性和强度方面存在局限性，本研究聚焦于超高性能混凝土（UHPC），通过用再生砖粉（RBP）替代部分水泥来增强普通C50混凝土，从而获得UHPC-NC试件。力学试验研究了UHPC-NC试件在各种条件下的粘结性能，包括界面剂、表面粗糙度处理以及在RBP替代率为30%的情况下，分别经过0、50、100和150次冻融循环后的粘结性能。此外，根据试验数据建立了界面粘结强度的多因素计算公式，并通过扫描电子显微镜（SEM）试验分析了粘结机理和模型。结果表明，与水冻融相比，盐冻融过程中UHPC-NC试件的界面粘结性能下降，造成的损伤更严重。然而，与未使用界面剂的试件相比，水泥浆试件的劈裂抗拉强度相对指标分别提高了14.01%和14.97%。使用界面剂提高了粘结强度和粘结性。未使用界面剂的UHPC-NC粘结模型可用三区模型表征。使用界面剂后，该模型可用三区三层粘结模型表征。总体而言，RBP-UHPC增强受损混凝土的C50表现出优异的界面粘结和抗冻性能。
