Diseño de un concreto permeable para la recuperación de agua / A pervious concrete design for water recoveryCarlos

The constant search for new construction methods that reduce the impact on our environment has led to the increasing use of environmentally friendly materials. Among the developments in sustainable construction are pervious concrete pavements. The main virtue of permeable concrete is the adequate management of rainwater, which infiltrates through this concrete favoring the recharge of aquifers and preventing flooding of the areas where it is implemented. In this research, a permeable concrete was designed for use in car wash stations, so that the water can be recovered for treatment and reuse or discharged into sewage systems with a lower load of pollutants. The same cement, fly ash and silica sand were used as admixtures in the process. The results showed that concrete without fine aggregate and 15% silica fume as an admixture develops the necessary strength properties for this application at 21 days of age.
