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.

该项目将研究塑料材料的包含，如 如聚丙烯，进入混凝土，以确定对收缩的影响 和干燥复合材料。 要研究的概念是 控制塑料材料的可能有益效果 在复合材料的固化阶段混凝土开裂 材料 控制混凝土在养护过程中的裂缝， 从而增加耐久性 的材料。 其结果将对 高速公路路面、机场跑道、平板等建筑行业 建筑物和仓库、桥面和隧道的基础 磨擦片.
