This research entitled ““Influence of SIKA VISCOCRETE-40 HSCL admixture on the mechanical properties and durability of self-compacting concrete““ seeks to contribute to the chain of knowledge of methods to elaborate a high performance self-compacting concrete, in order to minimize the problems faced in the realization of anchored walls, as retaining walls in deep excavations, with considerable thicknesses, one-sided formwork, and due to the thrust forces of the volume of concrete to be poured involved, it is not possible to use mechanical vibration methods, because of the danger of opening the found, creating possible consequences in the quality, internal voids, crabbing, exposed reinforcing steel, etc. Added to this is the need to achieve early compressive strengths of the poured concrete, in order to anchor the wall and advance in the construction process, without forgetting a necessary degree of impermeability due to soils with considerable contents of total soluble salts in humid conditions, due to the proximity to the water table. Therefore, the main objective of this research was to determine the effect of Sika ViscoCrete-40 HSCL admixture on the flowability, segregation, compressive strength and water penetration depth of self-compacting concrete. Initially, aggregate characterization tests were carried out, then fresh concrete was tested by means of extensibility, V-funnel, J-ring, L-box and U-box tests, and then hardened concrete was tested for axial compressive strength and permeability. It was concluded that the admixture effect provides good workability, favorable axial compressive strength at early ages and reaches a beneficial low degree of permeability.
