Durability of Engineered Cementitious Composites (ECC) and Reinforced ECC (R/ECC) Structural Members
The durability of Engineered Cementitious Composites (ECC) stems from the intrinsically tight crack width even when strained to hundreds of times the strain capacity of normal concrete. The less than 100 μm crack width is autogenously controlled by the composite and does not depend on steel reinforcement. It is also independent of specimen size and thickness. As a result, transport properties such as permeation and chloride diffusion of ECC can be significantly lower than similarly strained concrete, even when steel reinforcement is used.
