| Abstract Scope |
A solution to mitigate floods and overflows in cities is the use of pervious concrete pavements. A concrete composed of a network of voids that allow water pass through, reducing the speed of surface runoff. The use of reactive powders concrete (RPC) makes possible to create a permeable material with high compressive strength, rare property in this type of concrete. The application of hot water bath curing allows an early strenght development, allowing the pavement material reach the market faster. Therefore, it was analyzed two pervious concrete mixes, with RPC: coarse aggregates ratios by weight of 1: 4.0 and 1: 3.5 and how the compressive strength behaves through hot water bath curing. The results show a significant gain in compressive strength in the early ages with hot water bath curing and that the permeability obtained by both analyzed mixes was satisfactory. |
