Self-compacting pervious concrete mix design for permeable concrete soakaway rings

Abstract

Permeable concrete soakaways store surface rainwater and let it seep slowly into the soil. This minimizes the risk of flooding, which is an increasingly larger problem because of climate change causing heavier and heavier rainfalls. In the present study, a self-compacting pervious concrete mix design is developed to use for permeable soakaway rings. A self-compacting mix design ensures a more uniform void distribution throughout the soakaway ring compared to the use of a conventional stiff pervious concrete mix design. The study is divided into two main parts: laboratory testing, in which the influence of the casting height on the void distribution is also considered, and full-scale casting of a 2.25-m-high pervious concrete soakaway ring. The overall conclusion is that a successful self-compacting pervious concrete mix design was developed by carefully balancing the use of a superplasticizer and stabilizer. Thereby, it was also possible to perform a successful full-scale casting.
