Quantitative solution of size and dosage of capsules for self-healing of cracks in cementitious composites
Haifeng Yuan and Huisu Chen

 
Abstract
    Self-healing (SH) technology of cracking is becoming a promising solution to improve the durability of cement based composites. However, little formula are available in the literature on determining the size and dosage of the self-healing capsules. Supposed that SH capsules will be broken and activated when they met cracks, a theoretical solution is developed to calculate the appropriate length of SH capsules based on Buffon
 
Key Words
    self-healing; geometrical probability; simulation verification
