Durability performance of latex modified nylon fiber reinforced concrete for precast concrete pavement applications
The mechanical and durability characteristics of latex-modified nylon fiber-reinforced concrete (LMNFRC) are investigated with a view to precast concrete pavement applications. Precast concrete pavement can mitigate various problems in the field, e.g., eliminating the need for concrete casting and curing on-site. Compared with conventional concrete, using precast concrete pavement minimizes the wait time following repairs, thus enabling the earliest movement of traffic. Concrete cracking is an issue in the field. In this study, the nylon fiber volume fraction (0, 0.05, and 0.1%) and the amount of added latex (0, 5, 10, and 15% of the cement weight) are varied, and the slump, compressive strength, flexural strength, chloride ion penetration, abrasion resistance and impact resistance are measured. Increasing the latex content improved the flexural strength, permeability resistance, abrasion resistance, and impact resistance of the LMNFRC. Increasing the volume fraction of the nylon fiber improves the same properties. These improvements are attributed to stronger bonding and greater impact absorption capability by the nylon fiber and latex.
