CURING AND CHLORIDE PERMEABILITY

The rapid chloride permeability test was used to evaluate the relative permeabilities of latex modified (lmc), low-slump dense (lsdc), superplasticized dense (sdc), and conventional concretes. The effects of age of concrete cured both under laboratory and field conditions were investigated. Permeability was found to be strongly influenced by time and curing conditions. Results of this study showed that, at all test ages, permeabilities of latex modified concretes were considerably lower than the other concretes tested. Permeabilities generally decreased with age, the largest decreases occurring for conventional and dense concretes cured under field conditions. Additions of water to restore slump led to significant increases in permeability for all of the concretes in this study. (Author/TRRL)
