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.
