Obtención de un hormigón con alta permeabilidad para utilización en pavimentos, resistencia a flexión de 4 MPa, usando materiales de la provincia de Pichincha

Abstract

The present investigation is carried out in order to obtain a concrete design with characteristics of high permeability and flexural strength of 4 MPa for use in pavements, taking as a guide the pervious concrete report of ACI 522R (2010); for this purpose, the design contain different aggregates belonging of: Pifo, San Antonio de Pichincha and Guayllabamba from Pichincha´s province, Ecuador. A pavement that presents high permeability will provide solutions that tend to recharge aquifers, reduce costs in the construction of urban drainage systems and avoid accidents or complications on roads that do not contemplate a correct solution for filtration or drainage of rainwater or other sources. The high permeability is verified by the ASTM C1701 / C1701M standard test on a slab (850mm long x 850mm wide and 200mm thick) of the different permeable concrete designs, in order to simulate the implantation of a permeable concrete as pavement. The capacity for use in pavements is analyzed by means of its resistance to bending, for which concrete beams are used to be flexibly tested according to the ASTM C78 / C78M standard.
