Workability, shear strength and build of wet-process sprayed mortars
conference contribution
posted on 2009-07-10, 15:27 authored by Simon Austin, Peter Robins, Chris GoodierChris GoodierThis paper, which reports on part of a three year research project into wetprocess
sprayed concrete for repair, examines the influence of rheology on the pumping and
spraying of sprayed mortars. The workability properties of seven commercially available prepackaged
repair mortars and six laboratory designed fine mortars were examined using the
Tattersall Two-point viscometer, the slump test, a build test and a vane shear strength test.
The Two-point apparatus was successful with low-workability mortars and the flow
resistance and torque viscosity of the mortars was determined. The vane shear strength test
provided an instantaneous reading of the shear strength of the mortars and is compared with
their slump. The build value, a measure of sprayability, is then compared with these two
workability parameters and the flow resistance in order to determine their inter-relationship.
