"VAC-LITE" is the
trade name for a naturally occurring structural lightweight
aggregate mined by California Lightweight Pumice,
Inc. "VAC-LITE" is produced at
our state-of-the-art vacuum processing plant for pumice
aggregate located in Little Rock, CA and is processed
and distributed exclusively by California Lightweight
Pumice, Inc.
Unfortunately, the general name, "Pumice"
is applied to a variety of material, of different purity
and differing chemical makeup. This particular deposit,
by the workings of nature over a period of time, is of
a uniformity and purity almost unmatched elsewhere in
the world.
"VAC-LITE" is a strong,
durable, porous glass Pumice aggregate of volcanic origin.
An ideal Natural material for use in structural
lightweight concrete. With the continuing increase in
energy costs, the use of a natural aggregate marks a return
to the economic principles associated with the use of
lightweight concrete, pumice was used in ancient Rome
over 2,000 years ago in the construction of the Pantheon,
the Coliseum, and the immense vaults of the public baths
and many other notable structures still standing today.
"VAC-LITE" produced
by California Lightweight Pumice, Inc. meets or exceeds
the requirements established by the American
Society of Testing Materials for use as an
aggregate in structural concrete and concrete block. This
aggregate has been approved for use by the International
Conference of Building Officials and by the Department
of Building and Safety, City of Los Angeles.
