Investigation of medium-term self-healing performance of strain-hardening cementitious composites incorporated with colloidal nano silica
Construction and Building Materials（2022）
Abstract
•Colloidal nano silica (CNS) improved the mechanical performance of the cementitious composite.•The regaining of the mechanical performance of the pre-damaged sample was improved by CNS.•The addition of CNS improved the hydration degree and pozzolanic reaction.
