ENHANCING THE STRENGTH OF PERVIOUS CONCRETE USING POLYPROPYLENE FIBRE

CONCRETE TECHNOLOGY

Pervious concrete pavement is an effective means to address important environmental issues and support green and sustainable growth. By capturing storm water and allowing it to seep into the ground, pervious concrete is instrumental in recharging groundwater, reducing storm water runoff, and Meeting U.S. Environmental Protection Agency(EPA) storm water regulations. In fact, the use of pervious concrete is among the Best Management Practices recommended by the EPA. This report provides the information obtained from a literature search, site visits, and a laboratory study of polypropylene fibers in Pervious concrete. The literature search yielded information from numerous laboratory studies of the material properties of polypropylene fiber reinforced concrete (PFRC). The literature showed that, for the low fiber volumes (0.15% and 0.2%) recommended by most manufacturers, there was marginal improvement in toughness, fatigue, impact resistance, permeability, shrinkage, and wear resistance. Limited construction has taken place on PFRC suitable for airport construction. Most construction has been of slabs-on-grade and structural slabs. The laboratory study showed that, at 0.2% percent by volume of fibers, the reinforced concrete enhances the strength of pervious concrete.
