“…PC is developed by mixing well-graded aggregate/fillers and a polymer resin that partially or fully substitutes the cement binder. Due to its advantages, PC is usually used in applications that require excellent resistance to aggressive environmental conditions [ 11 ], and high resistance to dynamic and cyclic loads (i.e., fatigue) [ 12 ]. Compared with conventional cement-based concrete, PC has several advantages, including low permeability, chemical resistance, high ductility, high mechanical strength, and excellent bonding with other types of surfaces [ 13 ].…”

Polymer concrete (PC) has been used to replace cement concrete when harsh service conditions exist. Polymers have a high carbon footprint when considering their life cycle analysis, and with increased climate change concerns and the need to reduce greenhouse gas emission, bio-based polymers could be used as a sustainable alternative binder to produce PC. This paper examines the development and characterization of a novel bio-polymer concrete (BPC) using bio-based polyurethane used as the binder in lieu of cement, modified with benzoic acid and carboxyl-functionalized multi-walled carbon nanotubes (MWCNTs). The mechanical performance, durability, microstructure, and chemical properties of BPC are investigated. Moreover, the effect of the addition of benzoic acid and MWCNTs on the properties of BPC is studied. The new BPC shows relatively low density, appreciable compressive strength between 20–30 MPa, good tensile strength of 4 MPa, and excellent durability resistance against aggressive environments. The new BPC has a low carbon footprint, 50% lower than ordinary Portland cement concrete, and can provide a sustainable concrete alternative in infrastructural applications.

“…Recently, nanoparticles such as nanoclay, carbon nanotubes, and carbon nanofibers were suggested by researchers to improve the mechanical properties of polymer concrete [16][17][18]. Jo et al [16] reported the ability to significantly enhance the mechanical and thermal characteristics of performance of UP polymer concrete using nanoclay.…”

“…Shokrieh et al [17] reported a reduction in the flexural strength of PC incorporating nanoclay. Daghash et al [18] showed the ability of COOH-functionalized multi-walled carbon nanotubes (MWCNTs) to improve the impact strength of epoxy PC. This improvement was attributed to the ability of functionalized MWCNTs to bond with the epoxy matrix and create a new epoxy-MWCNTs nanocomposite with improved impact and flexural strength [18].…”

Polymer concrete (PC) overlays are typically used in infrastructure applications, specifically bridges and parking structures, to provide durable protection to the structural system. However, PC suffers from cracking and crack propagation during its service life mostly due to fatigue. Fatigue cracking of PC results in limiting the service life of PC considerably. Monitoring of fatigue damage in PC can help extend PC service life.In this paper, we demonstrate the possible use of carbon nanotubes to monitor damage initiation and propagation in PC under fatigue loading. PC prisms were produced using epoxy polymer concrete with varying contents of multi-walled carbon nanotubes (MWCNTs). The percolation level of MWCNTs necessary to produce conductive PC was first determined. Fatigue testing using an AASHTO modified test set-up was conducted. Electrical conductivity of PC overlay was continuously measured during fatigue testing. Damage initiation and propagation in PC incorporating MWCNTs overlays can be detected and monitored.
