Journal ArticleDOI
Application of bacteria as self-healing agent for the development of sustainable concrete
TL;DR: In this article, a specific group of alkali-resistant spore-forming bacteria related to the genus Bacillus was selected for this purpose, and the bacterial spores directly added to the cement mixture remained viable for a period up to 4 months.
Journal ArticleDOI
Quantification of crack-healing in novel bacteria-based self-healing concrete
Virginie Wiktor,Henk M. Jonkers +1 more
TL;DR: In this article, a two-component bio-chemical self-healing agent consisting of bacterial spores and calcium lactate is released from the particle by crack ingress water, which results in physical closure of micro cracks.
Journal ArticleDOI

Jonkers +21 more
TL;DR: In this paper, the state-of-the-art of self-healing concrete is provided, covering autogenous or intrinsic healing of traditional concrete followed by stimulated autogenous healing via use of mineral additives, crystalline admixtures or (superabsorbent) polymers.
Book ChapterDOI
Self Healing Concrete: A Biological Approach
TL;DR: In this paper, the authors considered the heterogeneity of the composition of its principle components, cement, water, and a variety of aggregates, the properties of the final product can widely vary.
Journal ArticleDOI
Bacteria-based self-healing concrete to increase liquid tightness of cracks
TL;DR: In this article, the effect of the healing agent when incorporated into the mortar matrix and the evaluation of the recovery of liquid tightness after cracking and exposure to two different healing regimes (water immersion and wet-dry cycles) through water permeability tests was investigated.
