Abstract
Hydraulic concrete is prone to deterioration under the impacts of environmental and geological factors,and the development of efficient and rapid repair technologies is of great significance.Owing to their excellent bonding performance and compressive strength,silicate materials have broad application prospects in hydraulic concrete repair.Focusing on their repair applicability,this study investigates the performance differences between silicate materials and conventional cement mortar via comparative experi ments,optimizes the mix proportion,and analyzes the key factors influencing material performance.The experimental results demonstrate that the initial setting time of silicate materials does not exceed 25 minutes and can be precisely controlled.Furthermore,their overall performance is superior to that of conventional cement mortar:under the same freeze-thaw cycles,the mass loss is reduced by 15%,and the elastic modulus ratio is increased by 20%.This study confirms that silicate materials are an ideal material for the rapid repair of hydraulic concrete and can provide technical support and material solutions for related engineering projects.关键词
