Plastic Fiber Reinforced Concrete for Large, Restrained Structures

该项目将研究在混凝土中加入一种塑料材料，如聚丙烯，以确定对复合材料收缩和干燥的影响。要研究的概念是塑料材料在复合材料养护阶段控制混凝土裂缝的可能有益效果。在养护过程中控制混凝土的裂缝将导致更细小和更多的裂缝，从而提高材料的耐久性。其结果将对高速公路路面、机场跑道、用作建筑物和仓库基础的平板、桥梁甲板和隧道衬砌的建筑业大有裨益。

This project will investigate the inclusion of a plastic material, such as polypropylene, into concrete to determine the effect on the shrinkage and drying of the composite material. The concept to be investigated is the possible beneficial effect of the plastic material to control cracking of the concrete during the curing stage of the composite material. Controlling the cracking of the concrete during curing will result in finer and more numerous cracks thus increasing the durability of the material. The results will be of great benefit to the construction industry for highway pavements, airport runways, slabs as foundations of buildings and warehouses, bridge decks, and tunnel linings.
