SUSTAINED LOAD AND AGING IMPACT ON WATERPROOF MEMBRANES: A REVIEW OF CURRENT RESEARCH
Main article
Abstract
Building leakage is a prominent quality issue today. The application of waterproof membranes is the most widespread in waterproofing projects, and these membranes must consider the influence of external and various natural factors, primarily including the effects of external forces, natural conditions, and defects in concrete structures. Only by accurately analyzing these influencing factors can scientifically grounded and operable repair solutions be proposed. This paper reviews relevant academic literature and reaches the following conclusions: (1) Studying the mechanical properties of waterproof membranes, such as tensile strength and elongation at break, under adverse or accelerated conditions is an intuitive and effective method for evaluating their performance. Under sustained loading and stress, the performance of waterproof membranes generally declines, including reduced waterproofing effectiveness and mechanical strength. (2) Although waterproof membranes demonstrate good durability, factors such as light, heat, and oxygen can still negatively impact their performance. Utilizing these factors to induce aging is a common method among researchers and is worth considering. (3) The results indicate that the durability of waterproof membranes is primarily determined by the base material. The impact of sustained loading under high-temperature conditions is more pronounced, potentially leading to accelerated material fatigue and aging. Despite the existence of numerous studies and review articles exploring various aspects of waterproofing, there remains a significant lack of in-depth reviews specifically addressing the impact of waterproof membranes under sustained loading and their aging performance. Given the increasing importance of concrete durability and water resistance in construction, it is crucial to systematically evaluate the performance of waterproof membranes. This research aims to fill this gap by examining the behavior of waterproof membranes under sustained loading conditions and assessing their effects on aging performance. Understanding these effects is vital for optimizing concrete performance and addressing long-term water resistance challenges. The necessity for this review lies in providing a comprehensive analysis of waterproof membranes, guiding researchers and engineers in selecting appropriate materials and techniques to enhance concrete protection.
