The present investigation was carried out in Lima, at the facilities of the company Master Builders Solutions Peru SA (MBS), where the influence of the percentages of superplasticizer additives on the consistency of the concrete fluids was determined, the instrument used was the observation guide , test guide to analyze the data, statistical inference was used when crossing the data of the results, the problem posed corresponds to the rapid loss of consistency of the flowable concrete and not having an ideal dose for these types of concretes based on nature of superplasticizer chemical additives that allow us to modify aspects in fresh and hardened concrete achieving superior characteristics to conventional concrete (without additive), according to the studies, consistency values of 8 ½ to 10 ½ inches are presented when the% of additive is increased from 1.0 to 2.5% with water reduction from 8% to 22.5%, the compressive strength of f´c = 270 kg / cm2 without additive af´c = 643 kg / cm2 in the additive LBTPA-003-19 and f´c = 608 kg / cm2 for the additive LBTPA-002-19 at 28 days, with relationships a / c from 0.56 to 0.45, which means that the evaluated concrete can have initial strengths at 100% in 61 and 64 hours. It is possible to find the influence of the percentage of superplasticizer additives in the consistency of fluid concrete, having an improvement in its use to obtain fluid consistencies without the need to increase water to the mix, the optimal dose of the additive LBTPA-003-19 is 1.5% of the weight of the cement and the additive LBTPA-002-19 is 2.0% according to the proposed design.
