Development Toward Application of Crack Self-Healing Concrete to Actual Structures

JR East's Frontier Service Development Laboratory is developing crack self-healing concrete. This material will be able to fill cracks approximately 0.2 mm wide that have occurred due to hardening through compound precipitation. JR East can expect benefits, including construction and maintenance cost reduction, by not waterproofing underground structures after completing concrete development with crack self-healing concrete. Fresh concrete durability and properties, such as self-healing concrete liquidity at casting, were checked by JR East, taking actual structural application into account. Study results show that there will be no problem in applying self-healing concrete to actual structures since no significant difference exists between self-healing concrete and the normal mixture concrete it is compared to.
