摘要
针对普通水泥混凝土存在的刚度大、变形能力小和柔性不足等问题,提出在混凝土结构耐久性要求较高的地区,采用聚合物改性水泥混凝土进行公路混凝土构造物的修筑,可提高工程耐久性能,通过微观形貌观测和孔结构分析等手段,着重对混凝土的微观结构进行了研究。
Aiming at existing problems like large rigidity, small deformability and insufficient flexibility and so on of common cement concrete, the area with higher requirement on durability of concrete structure is put forward, the polymer modification cement concrete is adopted to construct the highway concrete structure, so as to improve the endurance quality of the project. Through some means like micro morphology observation and pore structure analysis and so on, the research on microstructure of concrete is made emphatically.
