Title: Evaluation of Low-Cost Engineered Cementitious Composites with Incorporation of Cellulose Nanocrystals
Performing Institution: Louisiana State University
Principal Investigator: Marwa Hassan, Louisiana State University
Start and Anticipated Completion Dates: 01/01/2026 to 01/15/2027
Abstract: Cellulose nanocrystals are a type of nanomaterial derived from cellulose, which have gained interest due to their effect on concrete materials. This research study aims to investigate the effect of Cellulose nanocrystals on the mechanical properties of cost-effective Engineered Cementitious Composites (ECC). To accomplish this goal, four levels of nanocellulose will be evaluated. In addition, two types of Engineered Cementitious Composites mixtures will be assessed; one with sugarcane bagasse ash (SCBA) and without SCBA. A comprehensive experimental program will be conducted to evaluate the compressive, tensile, and flexural performance of the Engineered Cementitious Composites mixtures. Results will provide insights into the effects of nanocellulose on the mechanical behavior of low-cost Engineered Cementitious Composites materials.  

The scope of this study is to investigate the effect of cellulose nanocrystals on the mechanical properties of cost-effective Engineered Cementitious Composites. The objectives of the proposed research are to synthesize cellulose nanocrystals from rice husk through acid hydrolysis treatment, prepare two sets of mixtures of Engineered Cementitious Composites: one with SCBA as sand replacement and one without SCBA, evaluate the compressive, tensile and flexural performance of Engineered Cementitious Composites mixtures, and evaluate the cracking behavior of Engineered Cementitious Composites materials after uniaxial tensile test.
