abstract = {Small cracks in cement-based materials represent one of their primary weak points. To address this, self-sealing techniques have emerged, being one of them the use of bacteria and nutrients. The objective of this work is to analyse the effect that these nutrients have on the properties of mortars and pastes. To achieve this, yeast extract, calcium lactate and calcium nitrate were selected. For mortar characterisation, compressive strength, and shrinkage tests were developed. These tests were complemented with rheological tests stress growth test and flow curve test in pastes. The results demonstrate how the incorporation of these nutrients alters the properties of mortars and pastes, such as the decrease of almost 50% in early age strengths when yeast extract is used at 1.25%, the significant increase in shrinkage when lactate is employed at 4% by up to 81%, or the increase in fluidity when nitrate is used, among others.},
