Characterization of Regular Concrete and Low-Cost Engineered Cementitious Composites with Incorporation of Cellulose Nanoparticles and Cost- Effective Ingredients

Cellulose nanocrystals (CNC) are a special class of nanomaterials derived from cellulose, which is the most abundant natural polymer. These nanomaterials have gained growing interest due to their mechanical, chemical, optical, and rheological properties. This study aims to investigate the effect of CNC on the physical and mechanical properties of ECC and concrete materials. To accomplish the goal of this study, three levels of CNC dosage will be assessed for both ECC and conventional concrete. In the case of concrete, a structural class A1 concrete mixture will be prepared according to the Louisiana specifications. In addition, three different mixtures exhibiting different strength and ductility levels will be assessed for ECC. A comprehensive experimental program will be conducted to evaluate the mechanical properties of the prepared mixes (compressive strength, tensile strength, and surface resistivity as an indicator of concrete permeability). Furthermore, the microstructure and crack behavior of the prepared mixes will be evaluated using scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS). Results will provide insights into the effects of CNC on the fundamental properties of ECC and PCC composites. It is also expected that incorporating CNC into ECCs can further help the implementation of the readily available low-cost ingredients for optimum performance and cost.
