Influence of Mineral Admixtures on the Rheology of Cement Paste and Concrete
Rheological tests on cement paste were used to successfully select the type and dosage of mineral admixtures that improved concrete workability.

Resistance of Portland Cement Mortar to Chemical Attack
A report on a study on the resistance of concrete to chemical attack by various inorganic and organic compounds, undertaken using mortar bars (1.5 x 1.5 x 10 cm). About 1200 specimens have been placed under test, many have been exposed for more than two years. [PDF, 3.0 MB]

Heat-insulating from no-fines Lightweight Concrete
The major variables influencing the thermal conductivity of masonry materials are illustrated by taking blocks made from no-fines lightweight concrete as an example. With notes for an optimized product development. Reprint from Betonwerk Fertigteiltechnik 7/1999. [PDF, 1.2 MB]

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.
