CEE 6980 (Directed Studies): Engineered Cementitious Composites and Microstructural Analysis of ECC (Fall 2007-Spring 2008)
Prerequisites: Graduate student standing and permission from instructor
Project Description: · To assess the durability of PVA fiber-mortar composites (engineered cementitious composites) to wet/dry cycling (rain/heat cycling). Durability will be quantitatively measured through flexural strength and toughness (ASTM C 78 and modified ASTM C 947) and average residual strength (ASTM C 1399). · To qualitatively observe changes in the fiber-cement interfacial transition zone via environmental scanning electron microscopy (ESEM) after specific intervals of wet/dry exposure.
