Description / Abstract:
This method covers test methods and selection criteria for
prequalification of sealers for protecting new concrete or
prolonging the life of sound in-service concrete used in highway
structures. Sealer testing and evaluation for routine and job site
product quality assurance, field performance, and reapplication are
provided in the "Guideline for Quality Assurance, Job Site Quality
Control, and Reapplication of Protective Sealers for Portland
Cement Concrete."
Sealers are divided into two basic types: coatings, which remain
on the surface; and penetrants, which penetrate into the concrete
to some measurable depth and do not substantially change the
appearance of the concrete.
The values stated in SI units are to be regarded as the
standard.
