Abstract
We read with great interest the recent article by Erenson (2023)entitled “Dispersion characteristics of clayey soils containing waste rubber particles”. The author has studied the dispersion characteristics of clayey soils containing different percentages of waste rubber particles (WRPs) by performing several tests (viz. consistency limit, linear shrinkage limit, double hydrometer, crumb test and pinhole test) and scanning electron microscopy (SEM) analysis on five clayey (viz. Na-activated bentonite, refined ball clay, Ukrainian kaolin, Avanos kaolin and Afyon clay) samples containing 0%, 5%, 10% and 15% WRPs. It should be noted that Erenson (2023) has presented some interesting observations, but there are some serious issues that we want to share through this discussion and request the author of the original paper to address them to avoid their persistence in the scientific literature.
