MAKING MORE DURABLE CONCRETE WITH POLYMERIC FIBERS. CONCRETE DURABILITY. KATHERINE AND BRYANT MATHER INTERNATIONAL CONFERENCE, HELD AT ATLANTA, GEORGIA, USA, 27 APRIL-MAY 1987

The use of fibrillated polymeric fibers as secondary reinforcing to improve concrete durability is presented from a wide range of data with the purpose of demonstrating major trends. In this paper, results presented are focused on one type of polymeric fiber, a collated fibrillated polypropylene (cfp), at an addition rate of 1.5 lb/cubic yard (0.9 kg/m3). Tests on qualities that can affect durability illustrate cfp fiber reinforced concrete increases resistance to: plastic shrinkage cracking, impact, abrasion, shattering, freeze-thaw, deicing scaling, permeability, fatigue, and fire. The toughness index is increased up to 4.9 with the use of this fiber. Polypropylene will not degrade or corrode, and is not negatively affected by an alkaline environment of portland cement concrete. A great deal of research is being dedicated to the discovery of specific trends through lab testing. Once a trend is established, it is reconfirmed in the lab and then again in field applications. Since most durability properties are long term in nature, and cfp fibers are in their advent, future papers will discuss more conclusive results of research in this field. This paper is an attempt to characterize polypropylene fibers and their relative contribution to durability of concrete. (Author/TRRL)
