水下混凝土修补用环氧树脂复合材料的制备及性能影响机理
Preparation and performance influencing mechanism of epoxy composites for underwater concrete repair
摘要
Abstract
Underwater concrete repair materials are specialized substances designed for restoring submerged concrete struc-tures.Epoxy resin,with its rapid underwater curing capability,high strength,and superior adhesion properties,serves as an ideal base material for such applications.This study developed a water-based epoxy adhesive system and systemati-cally investigated the factors affecting its repair performance.The research examined the influence of component ratios,curing conditions,interface roughness,concrete strength,and surface environment on the composite material's bonding properties.Results indicated that optimal bonding strength was achieved after 7 days of underwater curing at 25℃,com-pared to shorter curing periods at higher temperatures.The study identified an optimal resin-to-curing agent ratio of 3.5∶1 and demonstrated that increased interface roughness and surface permeability significantly enhanced bonding perfor-mance.Furthermore,surface conditions such as extract presence or microorganism colonization were found to moderate-ly affect interface adhesion.These findings provide valuable guidance for optimizing underwater concrete repair applica-tions.关键词
