ABSTRACT
Abstract The total chemical shrinkage and the volumetric autogenous shrinkage have been determined experimentally for cement pastes incorporating different amount of the following additions: silica fume, fly ash, a silicate mineral filler fine (< 125 mm), medium (< 250 mm) and coarse (< 2 mm). The inert fillers were found to have little effect on the total chemical shrinkage; i.e. on the rate of the reaction of the cement. The effect on autogenous shrinkage is also minor; i.e. the implication is that volume change data determined on pastes are also relevant to concrete. The active additions silica fume and fly ash influence both types of volume change, as expected. Linear and volumetric measuring methods on the concrete are compared. Keywords: chemical shrinkage, filler, mortar, paste, sand, shrinkage measuring methods, silica fume.
