Abstract

This project studied a biologically based concrete repair method to understand micro-characteristics and durability. Scanning electron microscopy (SEM) and rapid chloride permeability testing (RCPT) were used to study an enzyme modified (CA-Add) concrete and ordinary portland cement (OPC) concrete. Inter-facial bonding of the repair to CA-Add substrate was visible in SEM. Permeability of CA-Add was lower than OPC. Results showed differences between the concrete mixes, however further research is recommended.
