Effect of Drying on Clay Clogging of Pervious Concrete ...

Clay drying may cause difficult-to-recover clogging due to two factors, namely, drying increases particle-to-particle cohesion and particle adhesion to pore walls, and drying causes particles to shrink to form aggregates that are larger than the pore size. This study facilitates the development of effective pavement maintenance strategies.

Characterization of drying behavior of granular materials ...

2014-9-1  It was then ground and sieved to achieve the desired particle size. Clay denoted 44‐12 R was found to have 9.8 wt% of particles above 150 μm, 23.4 wt% between 150 μm and 38 μm, and 66.8 wt% below 38 μm. Particle size distribution is an important parameter in determining the drying behavior of clay.

How to Find and Test Your Own Native Clays

Few things are as exciting as finding your own clay materials and then using them to make your own pottery. Especially if the items you make are strong, durable, functional and safe. Given the effort you likely won't save money compared to buying prepared bodies (unless you use alot of clay and can scale up the processing).
