The shape and roughness of aggregates play a predominant role in the properties of cement mixes.Due Host-parasite interactions between the piranha Pygocentrus nattereri (Characiformes: Characidae) and isopods and branchiurans (Crustacea) in the rio Araguaia basin, Brazil to that, some regulations limit the content of manufacture fine aggregate at 30% of the total of fine aggregate in concrete.However, few design methods consider the shape and roughness surface of aggregates in the mix proportioning.

This study presents an optimization method to increase the percentage of manufactured fine aggregates to be used, based on the void volume of the aggregates and their correlation with the fresh properties of mortars.To achieve that, the characteristics of the fresh and hard state were evaluated Acteoside and ursolic acid synergistically protects H2O2-induced neurotrosis by regulation of AKT/mTOR signalling: from network pharmacology to experimental validation in order to carry out a comprehensive analysis on the influence of the method on the performance of mortars.From the results emerges that it is possible to maximize the content of manufactured aggregates without detrimental effects on compressive strength.
