钢筋混凝土结构的耐久性是许多研究人员关注的主要问题。乳胶改性混凝土（LMC）在建筑中的使用促使研究人员审查和研究其不同的性能。这项研究是对聚合物在混凝土中的使用进行全面调查的一部分。本研究的主要目的是调查和评估苯乙烯-丁二烯乳胶改性混凝土 (LMC) 与传统混凝土相比的主要耐久性方面。此外，还使用扫描电子显微镜 (SEM) 研究了 LMC 的主要微观结构特征。LMC 的 SEM 研究表明，与传统混凝土相比，其微观结构存在重大差异。事实证明，LMC 的耐久性优于传统混凝土的耐久性，特别是其水密性（通过水渗透、吸收和吸着性测试来测量）、耐磨、腐蚀和抗硫酸盐性。 (C) 1997 爱思唯尔科学有限公司。
The durability of reinforced concrete structures represents a major concern to many investigators. The use of latex modified concrete (LMC) in construction has urged researchers to review and investigate its different properties.This study is part of a comprehensive investigation carried on the use of polymers in concrete. The main objective of this study to investigate and evaluate the main durability aspects of Styrene-Butadiene latex modified concrete (LMC) compared to those of conventional concrete. Also, the main microstructural characteristics of LMC were studied using a Scanning Electron Microscope (SEM).The SEM investigation of the LMC showed major differences in its microstructure compared to that of the conventional concrete. The LMC proved to be superior in its durability compared to the durability of conventional concrete especially its water tightness (measured by water penetration, absorption, and sorptivity tests), abrasion, corrosion, and sulphate resistance.
