Lu, Leung & Li 2018 - Flaw distribution and cracking strength in ECC

Citation

Lu, C., Leung, C.K.Y., Li, V.C. (2018). Flaw distribution and cracking strength in Engineered Cementitious Composites (ECC). Cement and Concrete Research, 107, 64–74.

Atlas role

• Key paper for quantifying flaw distribution and cracking strength.
• Important follow-up to artificial flaw and matrix tailoring concepts.
• Directly linked to Victor Li book Chapter 2 references, Ref. 37.

Why it matters

Victor Li book Chapter 2 states that matrix cracking strength depends on matrix toughness and flaw size. This paper is a direct modern source for translating that concept into flaw distribution and cracking strength analysis. It is important for formalizing EPS bead flaw design in low-fiber EGC/ECC.

Key claims to verify from original PDF

• Methods for flaw distribution measurement.
• Statistical relationship between flaw size and cracking strength.
• Whether flaw distribution is measured by CT, sectioning, or other image-based methods.
• How the study handles bridged versus unbridged flaws.
• Transferability to EPS bead systems.

Status

• Source in Victor Li book: confirmed.
