Abstract

Abstract

En 中文
• Applicability of bacteria based self-healing in CACs was Investigated. • The effects of self-healing nutrients on the mechanical properties, phase assemblage, and reaction kinetics of CAC were examined. • Nutrients enhanced the compressive strength of CAC. • Dissolution of CAC was limited due to the addition of yeast extract and calcium lactate. • Addition of yeast extract and calcium lactate retarded the reaction kinetics.
