ABSTRACT
Abstract This paper deals with the consistency of fresh lightweight polyester mortars as high-performance or multifunctional building materials. Fresh lightweight polyester mortars using an unsaturated polyester resin, lightweight fillers and aggregate are mixed with various mix proportions, and tested for slump as a measure of consistency. The influences of mix proportioning factors on the slump of the lightweight polyester mortars are examined, and the empirical equations for the slump predictions are successfully proposed. Keywords : Artificial lightweight aggregate, binder content, consistency, filler-binder ratio, lightweight polyester mortars, slump, slump predictions, unsaturated polyester resin.
