Abstract This paper presents a constitutive model that predicts the water retention behaviour of compacted clays with evolving bimodal pore size distributions. In line previous research, differentiates between present inside saturated pores clay aggregates (the microstructure) and macrostructure). A new formulation is then introduced to account for effect macrostructural porosity changes on soi...

The presence of soil solids, water, and air complicates understanding unsaturated dynamics. A thorough behavior is essential for the fruitful design slopes, embankments, retaining structures. series constant void ratio confining pressure triaxial compression tests were carried out under water content conditions (pore drained pore undrained) to study shear strength deformation characteristics a ...

Thickening is the first step in the design of sustainable (cost effective, environmentally friendly, and socially viable) tailings management solutions for surface deposition, mine backfilling, and sub-aqueous discharge. The high water content slurries are converted to materials with superior dewatering properties by adding long-chain synthetic polymers. Given the solid and liquid composition o...

Portland Cement Pervious Concrete (PCPC) is becoming more utilized across the U.S. due to increased requirements for stormwater management. This paper details the experience of the installation of a PCPC test section/parking area in Sioux City, Iowa. In order to evaluate a large number of mixture designs, the test section incorporated five different mixtures, each placed with and without air en...
