Two recent trends have significant consequences for the design of drilled shaft concrete. First, longer service lives make drilled shaft durability imperative. Second, larger drilled shafts increase the challenges of providing workable, stable concrete mixes that avoid damage due to thermal distress. Dan Brown and Associates will deliver a webinar to present challenges associated with concrete for drilled shafts, especially large-diameter drilled shafts. DBA engineers will discuss requirements for workability, stability, and long-term durability, including with respect to thermal issues. They also illustrated a design methodology for predicting drilled shaft concrete temperatures to establish performance criteria.
Keller North America provides a wide range of geotechnical engineering and construction services to improve soils in place and to both construct new and rehabilitate foundations. The techniques that will be discussed include Compaction & Jet Grouting, Earth Retention and Shoring, Vibro Compaction & Replacement, Micropiles, Soil Mixing for Deep Basement Excavations, and Pile Driving. Within our range of services, a Ground Modification solution is generally available for the toughest subsurface conditions.
