Preparation and Performance Study of Pervious Concrete with Water Purification

Pervious concrete has a certain degree of air permeability and water permeability.In this paper,the preparation of pervious concrete by modified bentonite instead of aggregate is studied,with the influence of factors like the modification temperature,dosage,blending mode and particle size on the performance of pervious concrete analyzed.The experimental results show that the incorporation of 20% of modified bentonite can not only ensure the strength and water permeability of the pervious concrete,but also increase the adsorption rate of Rhodamine B solution up to over 70%.
