In the present investigation, high strength concretes prepared with different percentages of Nanosilicate (GAlA NANOSILICE) (0.3%, 0.5%, 0.7%) are studied, based on a concrete pattern (CP) designed with a Superplasticizer (viscocrete sc-50), in a dose of 0.1% with respect to the weight of the cement, the main objective was to determine as it increases the mechanical resistance to compression in different doses of Nanosilica added on the basis of the Standard Concrete. For this, it was proposed to design concrete mixtures according to the methodology proposed by the ACI 211.4 for the compressive strengths of 420 and 600 kg / cm2, using three dosages of nanosilicate additive of 0.3%, 0.5% and 0.7% by weight of cement for each resistance, and taking into account parameters for concrete with additive of 1 to 2 inches according to the ACI 211.4 for the concrete pattern (without additive), which serve to establish concrete properties such as its workability and consistency. After having the appropriate dosages, we proceeded to the preparation of each one of these, performing the following tests on the concrete in fresh state: settlement (Slump), temperature, volumetric unit weight and percentage of air; Subsequently tests were performed on concrete in hardened state: resistance to compression at 3, 7 and 28 days of age, as a result of the compression resistance analysis process it was possible to know the most optimal Nanosilice additive which is 0.5%. To define the dosages of nanosilica additive and superplasticizer, the manufacturer's recommendation was used, which established a range of 0.5% to 3.0% and 0.5% to 1.8% respectively, the dosages of the aggregates were split according to the design methodology of the ACI 211.4 committee. For 420 kgf / cm2 the optimum content is 0.80% achieving resistance of 448.10 kgf / cm2. For 600 kgf / cm2 the optimum content is 0.80% achieving resistance of 637.60 kgf / cm2.
