项目摘要
This proposed project aims to produce an innovative green surface treated fiber for use as reinforcement by the construction industry. The proposed project aims to use a patented technology to coat monofilament fibers of polypropylene and glass with pozzolanic material or supplementary cementitious materials (SCMs) like fly-ash and silica fume. The variables noted above including two lengths; a micro fiber (length <20mm) and a macro fiber (length >40mm) will result in eight different types of fibers. One of the main objectives of this project is to design and construct a prototype conveyor system with tow feed, adhesive spray/heat system, followed by SCM spray/curing chamber, and finally a chopping and bagging system. Microscopy and confirmatory product testing will allow for creating a fiber specification sheet for all the 8 products produced. Owing to the siliceous coating on the surface of these engineered fibers, these fibers develop superior (less voids) Interfacial Transition Zone (ITZ) with the cement matrix resulting in improved and more durable bonding. Addition of micro fibers in concrete is well known to reduce shrinkage cracking and combined use with macro fibers can add the otherwise lacking post crack strength in brittle matrix of concrete. The involvement of various external stakeholders will allow us to meet the project goal of rapid deployment of the fibers produced using this technology.
该拟议项目旨在生产一种创新的绿色表面处理纤维,供建筑行业用作加固材料。拟议项目旨在使用专利技术,在聚丙烯和玻璃单丝纤维上涂覆火山灰材料或辅助胶凝材料(SCM),如粉煤灰和硅灰。上述变量包括两种长度;微纤维(长度<20 mm)和宏纤维(长度> 40 mm)将产生八种不同类型的纤维。该项目的主要目标之一是设计和建造一个原型输送系统,包括丝束进料、粘合剂喷涂/加热系统、SCM喷涂/固化室,最后是切碎和装袋系统。显微镜检查和确认性产品测试将允许为生产的所有8种产品创建纤维质量标准表。由于这些工程纤维表面上的硅质涂层,这些纤维与水泥基质形成了上级(较少空隙)界面过渡区(ITZ),从而导致改进的和更持久的结合。众所周知,在混凝土中添加微纤维可以减少收缩开裂,并且与宏观纤维组合使用可以增加混凝土脆性基质中否则缺乏的裂缝后强度。各种外部利益相关者的参与将使我们能够实现使用该技术生产的纤维快速部署的项目目标。
