Abstract:
During the past year, a severe odor developed in some
floors of a large office building. The odor has been
attributed to interactions among a self-leveling
compound, carpet adhesive, and the carpet. The owner of
the building, the General Services Administration (GSA),
wanted to ascertain if the odor could be eliminate by
removing the existing self-leveling compound and
replacing it with a compound of a different composition.
The National Institute of Standards and Technology
(NIST) was asked to evaluate the properties of selected
self-leveling compounds being considered for use in the
building. Lightweight concrete was also to be tested
for possible use as a substrate for the self-leveling
compounds. This report gives the results obtained on
the self-leveling compounds alone or in combination with
normal weight concrete or lightweight concrete. It also
gives the test results obtained on lightweight concrete
alone. An overall ranking of the compounds was not
attempted, because the rank would depend on the weight
given to each property by the user in each application
of the compound. Specifications for some of the
properties tested were developed by GSA. It was not the
aim of this study to measure or observe any odor
generated by the self-leveling compounds alone or in
conjunction with the concrete substrate or any other
material.
