Estudo experimental do concreto permeável para pavimentação

Abstract

The porous paving is a sustainable alternative that allows the rainwater’s infiltration, leading it back to the water table, without it overloading the drainage system, mitigating the urban floods’ highs. This work’s purpose was to study porous concrete destinated to permeable paving’s covering in pedestrian’s traffic’s areas. Two different concretes were made with the variation of the characteristic maximum diameter of the coarse aggregates to identify the influence of itself in the concrete’s physics and mechanical characteristics. In this regard, tests were made, including: apparent dryness specific mass, loopholes rates, constant load permeability and uniaxial compression resistance. According to the results, the relation within the characteristics determinated in the tests and the characteristic maximum diameter was analyzed in the concrete’s trace. It was belived that the characteristic maximum diameter of the coarse aggregate didn’t influence the studied characteristics, but rather the range of particle size variation of the employed aggregate. The trace with more uniform variation presented better results in all characteristics.
