The purpose of this research is the analysis of pervious concrete without the use of additives, with coarse aggregate form the Vilcanota River, Pampaccahua sector. Pervious or porous concrete is a concrete with zero slump, a high porosity and a high ratio of voids, it consists of Portland cement, coarse aggregate, and a little or none use of fine aggregate and water. The combination of these materials will produce a hardened material with connected pores, which allows water pass easily through them. The importance of this research is the achievement of a compressive strength of fc = 210 kg / cm2 at 28 days of age, with a percentage of 15% of voids, without the addition of any additives. Various attempts were used to achieve a water - cement ratio to get a zero slump and a workable mix, important factors for this type of concrete. The achieved ranges of permeability are between 0.2 to 0.54 cm/sec, 24 concrete briquettes were made with 15% percent of voids, also 24 concrete briquettes were made with 20% of voids; all of them were tested at the age of 7, 14, 21 and 28 days, different results were obtained, it was noticed that with higher percentage of voids in our concrete lower resistance is reached.
