摘要

A solution to mitigate floods in cities is the use of pervious concrete pavements. This is a concrete composed of a structure of interconnected voids allowing the flow of water, reducing the speed of surface runoff. Reactive powders concrete, with the addition of coarse aggregate, propitiates the creation of a pervious material combined with good resistance, hardly found in this type of product. The application of thermal curing allows an acceleration of resistance gain in young ages, making the pieces reach the market in less time. Therefore, we sought to study two traces of pervious concrete with RPC ratios: 1:4.0 and 1:3.5 gravel in mass, evaluating the resistance behavior by means of thermal curing. Significant gain in compressive strength is achieved in the early ages with thermal curing, and the permeability obtained by both lines analyzed was satisfactory.
