Influence of mix and environment on plastic shrinkage cracking

The influence of mix constituents (including corresponding concrete grade), retarding and air entraining admixtures and PFA additives, and the effect of environmental factors on plastic shrinkage cracking of mortar specimens is reported, supplemented by concurrent evaporation and bleeding tests. The dominant effect of environmental factors on evaporation, and that of corresponding concrete grade on plastic shrinkage cracking, were clearly...
