“…In bioconcretes with Sporosarcina pasteurii, in addition to the substrate [23,26] and type of aggregates [14,39,42] used in the designs, interestingly, its effect was evaluated when subjected to special conditions, such as compressive strength, crack depth, as well as the water/cement ratio in the mix [41]. In relation to experimental designs with increasing stimulus, it has been applied in relation to the bacterial concentration [17,28,36,43,44], substrate [36,45], recycled aggregate [28], fly ash [44,46] and fiber used [11,47]. It has been shown that increasing up to a certain bacterial concentration favors the properties of concrete, as long as the curing water is potable, since these are reduced if salt water is used, but this is not the case with Dunaliella salina, which has the ability to improve the properties of concrete and even more when increasing its concentration in the mixture and this is due to the fact that it is halophilic [17].…”
