Table 1 Different types of rheometers.

a

ICAR Rheometer

Vane-in-Cup

(rotating vane

inside a cup)

Vane radius

63.5 mm; cup

radius 143 mm;

vane height ~ 

127 mm

Rugged, portable

instrument for

measuring yield

stress and plastic

viscosity of fresh

concrete.

b

SLIPER (Sliding

Pipe) Rheometer

Vertical sliding pipe,

piston-driven

Tube diameter

unspecified (lab

scale device)

Designed to assess

pumpability of fresh

concrete; measures

pressure and

displacement to

derive pumpability

and pressure

losses.

c

Plane–Plane

Tribometer

Flat plate vs.

flat plate

Plate separation as

per simulating

formwork conditions

Measures frictional

resistance at the

concrete–formwork

interface under

conditions simulating

site pouring

induced flow

behavior to estimate

workability of

concrete .

Research-grade

device for flow and

deformation testing

of concrete; specific

geometry/gap not

detailed in

accessible sources

h

for measuring shear

properties,

viscosity, and flow

curves in concrete

and other materials
