Use of image analysis to study top surface clogging of pervious concrete

Pervious concrete is a type of sustainable concrete that can prevent excess urban runoff and increase groundwater storage. Though pervious concrete has a lot of advantages as a sustainable building material, the main disadvantage is the low strength and clogging of its concrete matrix. Clogging takes place in the top layers of the concrete matrix. The paper discusses image analysis on the top surface of pervious concrete to understand clogging patterns. The clogging material used is clay and sand. The image analysis is done in ImageJ software. The statistical analysis is done in R. The sand clogging of the pores is predominant compared to clay clogging since the aggregate size used is 2.36mm to 4.75mm, and the clogging sand particle size ranges from 1mm to 6mm. Since the top surface is the deciding surface for the overall clogging of the pervious concrete mix, a detailed analysis of the pore distribution becomes essential to predict the clogging of the concrete.
