Soft Soil Remediation with Permeable Low-Density Cellular Concrete

This paper will address the feasibility of using permeable low-density cellular concrete (PLDCC) in soft soil remediation applications. In discussing this feasibility, the paper will review and evaluate data from recent studies conducted at the University of Missouri-Kansas City related to the physical properties of PLDCC, including permeability, infiltration, freeze/thaw cycles, shear strengths, and void structure. This paper will cover the most typical applications for the utilization of PLDCC and take a brief look at the constructibility and cost considerations. Three specific case studies are examined, including a wall abutment project in Bellingham, WA, a structural foundation project in New Orleans, LA, and a sinkhole remediation project in Chester County, PA. All three of these case studies utilized 25-35 pcf (pounds per cubic foot) (400 and 560 kg/m(3)) PLDCC for soft soil remediation.
