UWM-CBU Concrete Materials Technology Series Program No. 72 Construction Demonstration for Use of Residuals and Reject Fibers from Pulp and Paper Industry in concrete and CLSM
Sponsored

Department of Natural Resources, Madison, WI
August 28, 2008, Best Western Midway Hotel-Brookfield, 1005 S. Moorland Rd., Brookfield, WI, and New Berlin Redi-Mix, Inc., 20500 W. Lawnsdale Rd., New Berlin, WI
Workshop Description The
purpose of this 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 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 in CLSM.
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.
State-of-the-art information will be presented.
