Self-healing of cement mortars based on fly ash and crystalline admixture

The actual study has followed the effect of fly ash and crystalline admixture on cement mortars' mechanical self-healing properties. Three types cementitious mortars composed (i) 16 wt.% ash, (ii) admixture, (iii) were compared to standard mortar (in compliance with EN 196-1). capillary water absorption determined sealing efficiency cracks over a period time. experimental results showed that by autogenous 40% after 28 days treatment 70% 6 months treatment, but addition admixtures stimulated self-healing. best containing where achieved 79% 98% months.
