This research was conducted to evaluate the behavior of the concrete to which was added Microsilica 10% by weight of cement and superplasticizer at rates of 0.5%, 1.0%, 2.0% and 3.0% by weight of cement in three brands different, the most representative of the market. I concrete were made with Portland cement IP brand “YURA“ fine quarry Pampas and coarse aggregate 1 “Quarry Huancabamba city of Andahuaylas, department of Apurimac added; the Microsilica used the brand SIKA - FUME, and superplasticizer on brands: Chema SUPERPLAST, Sika Sikament® 290N and Euco 37, corresponding to the classification of superplasticizer type F; the mix design for the particular pattern and concrete additives was performed by ACI method. a specific resistance to compression quality fc = 210 kg / cm2, for which we started to perform the respective assays Aggregates (specific gravity, unit weight, moisture absorption, particle size), the fresh concrete (designed settlement) and hardened concrete (axial compressive strength of the concrete); we proceeded to the development of the briquettes to be evaluated compression 7, 14 and 28 days. These mechanical properties (compressive strength) and physical (consistency and unit weight) were assessed for each type of concrete so that it was determined that the concrete superplasticizer microsilica and 10% reached a strength fc = 396 kg / cm2 , higher than the specific quality standards Fc = 210 kg / cm2. For the consistency of concrete test, it was possible to obtain a higher slump to 6 “superplasticizer added more than 1%, which gives us a fluid consistency so that the concrete is pumpable. Corresponding to unit weight of concrete superplasticizer added microsilica and 10% a decrease in direct proportion to the percentage of superplasticizer unit weight was obtained.
