Partnership for Advancing Technology in Housing: Extruded Fiber-Reinforced Cement Composites for Residential Construction

摘要混凝土比木材更坚固、更耐用、更耐火、性能更稳定，是住宅建筑的良好材料。然而，素混凝土相对脆弱和沉重。这些缺点可以通过特殊的加工技术和纤维增强来克服。最近，在西北大学ACBM中心，挤压技术已被应用于高性能纤维增强复合材料的生产。在这个过程中，高粘性的水泥膏体和微纤维混合物被强制通过所需截面的模具。与传统混凝土相比，挤压组合物更坚固，延展性更强，更不透水。这项研究的目的是开发适用于住宅建筑的高性能挤压复合材料，特别是先进的面板系统。复合材料的设计将实现PATH的目标，提高耐久性，降低维护成本，降低生命、伤害和自然灾害造成的财产破坏的风险。不同的截面，重点是蜂窝结构，将开发用于生产轻量化元件和先进的面板系统。与芝加哥住房委员会和建筑行业供应商的合作将提供向建筑商和承包商介绍这些产品的途径。

EXTRUDED FIBER-REINFORCED CEMENT COMPOSITES FOR RESIDENTIAL CONSTRUCTIONPROPOSAL ABSTRACTConcrete can be stronger, more durable, more fire-resistant, and perform more consistently than wood, making it a good material for residential construction. However, plain concrete is relatively brittle and heavy. Those drawbacks can be overcome with special processing techniques and fiber reinforcement. Recently extrusion technology has been adapted for the production of high-performance, fiber-reinforced composites at Northwestern University's ACBM Center. In this process, a highly viscous mixture of cement paste and micro-fibers is forced through a die of desired cross-section. Extruded compositions are stronger, more ductile and more impervious to water than conventional concrete. The objective of this proposed research is to develop extruded, high-performance composites suitable for residential construction, particularly advanced panel systems. The composites will be designed to accomplish the PATH goals of improved durability, reduced maintenance costs, and reduced risk of life, injury, and property destruction from natural hazards. Different cross-sections, with a focus on cellular construction, will be developed for the production of lightweight elements and advanced panel systems. Collaboration with the Chicago Board of Housing and suppliers to the construction industry will provide avenues to introduce these products to builders and contractors.
