Dataset for "Air-entraining admixtures as a protection method for bacterial spores in self-healing cementitious composites: Healing evaluation of early and later-age cracks"

This dataset contains the experimental results obtained when evaluating the feasibility of using air-entraining agents (AEAs) as an economical and straightforward encapsulation method for bacterial spores in bacteria-based self-healing cementitious materials when cracks (~ 0.50 mm) are formed at an early (28 days) or later age (9 months).
The data included here corresponds to the following test methods:
1) Determination of air-content (BS EN 1015-7 (Method A- Pressure method)).
2) Flowability (BS EN 1015-3).
3) Compressive and flexural strength of mortar specimens (BS EN 1015-11).
4) Images and data used for determining the mean healing ratio of the complete cracks using image binarization.
5) Crack healing (%) as a function of the initial crack width for mortar specimens cracked after 28-days or 9-months of curing.
6) Improvement in water penetration resistance following RILEM test method 11.4.
7) Raman spectroscopy for 9-months-old mortar specimens after a healing period of 56 days.
8) Images and data used for determining the micro-bubbles total area and size distribution.
