Designing self-healing into cementitious materials can open a new world of opportunities for resilient concrete infrastructure under service loading conditions. The self-healing process should be robust as well as repeatable, allowing for self-repair after multiple damage events. The repeatability poses great challenges when self-healing strategies mainly rely on the formation of low-strength c...

This paper is a summary report based on the discussion of JCI-DFRCC committee. The paper attempts to summarize the terminologies related to DFRCCs and the structural advantages and application concepts of DFRCCs. The attempt is made for the purpose of further discussion at JCI International Workshop on Ductile Fiber Reinforced Cementitious Composites -Application and Evaluationheld in 2002 at T...

The work presented in this article attempts to evaluate the effect of partial and full substitution silica sand by fine recycled waste glass (RG) M45 engineered cementitious composites. Two groups with a total eight mixtures were prepared 2% or without untreated polyvinyl alcohol (PVA) fibers. Each group included four RG ratios 0, 30, 60, 100%. compressive strength flexural all tested at ages 7...

This paper presents a study on cracking characterization of engineered cementitious composites (ECC) under flexural cyclic load using digital image correlation (DIC) technique. Five stress levels, namely 0.65, 0.75, 0.8, 0.85 and 0.9 the strength, were applied. Strain map at side surface was obtained by DIC used to drive evolution midspan deflection, damage pattern, maximum crack width, number ...

In this study, iron ore tailings (IOTs) are used as aggregates to prepare iron-ore-tailing-engineered cementitious composites (IOT-ECCs) achieve clean production. Some mechanical indexes, such compressive strength (fcu), four-point flexural (ff), axial (fc), deformation properties, toughness, and stress–strain behavior, studied. The mass loss, fcu relative dynamic modulus elasticity (RDEM), det...
