Resumen
[EN] Nowadays the sustainability and safety requirements of structures inspire the study of new
self-healing materials and preventive repair methods on cementitious elements. To achieve this
undertaking, this research replaces widely employed synthetic polymers by biodegradable ones as
consolidants and water-repellents, and assesses the protection and consolidation effect of biopolymers
(obtained by using waste biomass of mixed microbial cultures from polyhydroxyalkanoates production
processes) as eco-friendly healing agents by analysing the water absorption of two kind of materials.
The first group of samples are cement mortar specimens whose external surface has been treated with
biopolymer products and subsequently evaluated by water drop absorption test. The second group of
samples are cement mortar specimens formulated with biopolymer products included in its mixing water
and later the waterproofing efficiency is analysed by capillary water absorption tests. The water
absorption behaviour of both kind of samples shows a potential improvement of cementitious elements
durability, since water absorption results have decreased for treated samples in comparison with
untreated ones
