The following research was aimed at studying the physical and mechanical properties of traditional concrete and comparing it with added polypropylene microfiber. The polypropylene microfiber is a building material which helps reduce cracking in the first 24 hours after casting, cracking caused by volume changes of concrete by loss of water in the mixture. The preparation of samples for testing were performed as indicated in the Peruvian technical standards (NTP) over concrete; cylindrical samples which were 30 centimeters high by 15 centimeters in diameter and 15 centimeters prisms base, 15 centimeters high by 50 centimeters in length 100% solid made with cement, aggregate and polypropylene microfiber. These samples were tested in different dosages, thus having a specific pattern without addition of microfiber, concrete added with 250 grams of microfiber per cubic meter of concrete, concrete added with 300 grams of microfiber per cubic meter of concrete and concrete added with 350 grams of microfiber per cubic meter of concrete. According to the results, conclusions were obtained, which emphasize that the greatest resistance to compression and bending increased with the addition of polypropylene microfiber in an amount of 300 g / m3, with higher and lower amounts increased resistance was lower. Consistency, obtained through the slump test, was diminished with the further addition of polypropylene microfiber. Thus it was demonstrated that polypropylene microfiber is a material which improves resistance to compression and bending of the concrete, but the consistency decreases with increasing addition of polypropylene microfiber.
