Workshop Description

The purpose of the workshop is to present important technical information and review production and construction aspects for the use of fibers from pulp and paper industry primary treatment residual solids in structural-grade ready-mixed concrete, as well as potentially in flowable slurry (CLSM). Flowable Slurry is a very low-strength concrete-like material that is usually made from one or more of the materials such as coal ash, wood ash, used foundry sand, post-consumer crushed glass, concrete sand, water, and some portland cement. The strength of the flowable slurry can vary from 50 psi to 1200 psi at the age of 28 days. Flowable slurry is being specified increasingly by municipalities, state highway departments, and engineers for many applications. The workshop will include a demonstration of use of residual solids in a structural concrete slab and placement, as well as slabs placement from similar previous activity. Handout materials will be provided. The workshop should be of interest to those associated with managing environmental challenges for pulp and paper mills, as well as engineers involved in durable concrete construction and design, architects, engineering technicians, engineers working in governmental agencies, industry and private practice, engineering faculty and students, as well as ready mixed concrete producers, aggregates suppliers, and contractors. Knowledgeable professionals will present state-of-the-art information.

Dr. F. Andrew Gilbert, Jr., Division Environmental Services Manager, Stora Enso North America, Wisconsin Rapids, WI.

Dr. Gilbert primarily provides support services in the areas of solid waste management and wastewater treatment to Stora Enso’s mills in North America. Dr. Gilbert has had an ongoing interest in beneficial use of solid waste and has been involved in the establishment of numerous programs at Stora Enso. He has authored and presented papers to the National Council for Air and Stream Improvement for the pulp and paper industry (NCASI) and the Technical Association of the Pulp and Paper Industry (TAPPI). He has also worked on technical advisory committees to state regulatory agencies in the areas of solid waste management and beneficial re-use.
