混凝土技术的发展与展望

Development and Prospect of Concrete Technology

混凝土是基础设施建设的主体建筑材料。继钢筋混凝土、预应力钢筋混凝土与纤维混凝土之后,基体微结构调控与性能提升将成为未来混凝土技术第四次飞跃的主要驱动力。本文从近年来混凝土技术发展现状与趋势两个方面入手,重点介绍了混凝土的工作性调控、裂缝控制、力学性能提升、耐久性提升四个方面的主要技术现状,同时对上述混凝土技术的主要发展趋势进行了展望。

Concrete is the used building material for infrastructure construction.Following the reinforced concrete,prestressed reinforced concrete and fiber concrete,the microstructure control and performance improvement of the concrete will become the main driving force for the fourth leap of concrete technology in the future.The recent development of workability regulation,shrinkage and cracking mitigation,mechanical properties improvement and durability improvement are reviewed.The prospective and main development trends are also introduced.
