For this purpose, two different mortar formulations were made with proportions of 1:6 and 1:7 (cement:natural sand). In addition, the composition of the mortars included the use of a plasticizing additive (additive mortar - AA) and household detergent (mortar with detergent - AD). The mortars were characterized in the plastic (consistency, density, water retention and air incorporation) and hardened (mass density, capillary and total water absorption, flexural and compressive tensile strength) states. For performance analysis, the permeability test was performed using the pipe method. The results showed that despite the difference in the proportions of cement: aggregate and the use of detergent in the composition of the coating mortars, all presented high workability/plasticity with cohesion of their particles. Regarding the properties in the hardened state, the variables evaluated in the research did not prove to be determining agents to the point of making them distinct from each other, according to some of the criteria of the NBR 13281-1 (ABNT, 2023) standard.Acesso AbertoAbsorção de águaPropriedades mecânicasAditivo plastificanteDetergenteWater absorptionMechanical propertiesPlasticizing additiveDetergentCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - Artigo
