T. Vickers et M. Moukwa, EVALUATION OF TEST METHODS AND ENVIRONMENTAL-CONDITIONS TO PROMOTE EFFLORESCENCE FORMATION UNDER LABORATORY CONDITIONS, Journal of testing and evaluation, 24(2), 1996, pp. 80-83
Several test procedures that induct formation of efflorescence on the
surface of porous block specimens were investigated. This paper descri
bes the tests that were investigated and the environmental conditions
under which these tests were performed. A wicking procedure, run at an
elevated temperature and low relative humidity, rapidly produces effl
orescence on the surface of test samples. The rate of effloresence for
mation was fastest at an elevated temperature and lower relative humid
ity and slowest at a cool temperature and high relative humidity. The
wicking test can be used to rapidly determine the effect of changing m
ix proportion and the effectiveness of sealers and anti-efflorescence
additives on the efflorescence potential of porous masonry units.
