Influence of soil contaminated water on clogging phenomenon of different void based pervious concrete

In many circumstances, water passing through pervious concrete (PC) is contaminated with soil sediments. Hence, in such cases, the clogging of PC affects its functional characteristics and service life conditions. The clogging behaviour of different void based PC under the influence of soil-contaminated water is not yet clearly understood. This study explores the effect of using three different kinds of soil-contaminated water such as sand contaminated water, clayey silt contaminated water, and a mixture of sand and clayey silt contaminated water on the pore clogging phenomenon of different void based PC. Three different concentrations of soil contaminated water for each kind of PC were employed for carrying out clogging process in this present study. The clogging process was executed until reaching the minimum permeability level of the PC. This paper also elucidates the effectiveness of the washing process on the de-clogging behaviour of each clogged PC. In addition to this, various characteristics of different void-based PC, such as, strength, permeability, macroscopic pores distribution, and leaching parameters, were assessed. The outcomes of the experimental research work disseminate consensus behaviour of PC that would be helpful to provide a conceivable solution to develop the desirable performance of PC for wide applications.
