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.
