Abstract:
This interdisciplinary study focuses on enhancing the durability of concrete with protein admixtures and denaturing chemicals. By subjecting proteins to denaturation using specific chemicals such as lignin, SDS, and urea, modifications are induced on the molecular structure of proteins to improve their physico-chemical properties, including electrostatic charge and size and surface tension. The denatured proteins are then incorporated into cement paste, and their impact on properties like microstructure, sorptivity, freeze-thaw, hydrophobization and bulk resistivity are evaluated. The findings shed light on the potential of proteins in different molecular conformations (native and denatured) in concrete and their enhanced durability and resiliency to harsh environmental conditions like freeze-thaw. This research contributes to the ongoing efforts in developing bio-inspired approaches to improve the performance and environmental compatibility of concrete materials and admixtures.
