The role of SCM’ s on rheology of sprayed mortar

Popis výsledku v původním jazyce

The role of various SCM’s on rheology of fresh sprayed mortar was studied. The mix design was inspired by recent trends in SCM’s with use of ground limestone, calcined clays and natural pozzolanas. New formulations were correlated to commonly used SCM’s like blastfurnace slag and fly ash. Sprayed mortar designed mostly for thin profile coatings is demanding material in terms of rheology requiring good adhesion, pumpability, shootability, stability after spraying, low segregation and minimum rebound. Particle packing model was used for sprayed mortar mix design. Time and shear rate dependent rheological parameters were calculated using conventional models to describe the properties of fresh sprayed mortars. A procedure for determining the segregation of the mortar using a rheometer was proposed.
