Stress Due to Alkali-Silica Reaction in Mortars
A test method and test apparatus is presented. It does not measure the length change but measures
the stress generated by the swelling of the gel. The force required to prevent expansion is
measured over time while the specimen and frame are immersed in a solution of 1-N NaOH at 50°C.
With some test results.

Modified Slump Test to Measure Rheological Parameters of Fresh Concrete
The ease of placement of concrete depends upon at least two physical properties, the yield stress
and plastic viscosity. Currently the most common field test is the slump test, and it is related
only to the yield stress. Therefore, a simple field test method intended to provide an evaluation
of the two Bingham rheological parameters, yield stress and plastic viscosity, was developed.
Description of apparatus and test procedure.
