Alkali-Silica Reaction and High Performance Concrete
Answers the question if high-performance concrete is susceptible to alkali-silica reaction. The paper contains details on the alkali-silica reaction mechanism and the factors influ…
Argument for Using Coarse Cements in High-Performance Concretes.
Investigation of the effects of particle size distribution and water-to-cement ratio on hydration kinetics. Printed in: Cement and Concrete Research, 1999. Besides an abstract, the…
Assessment of Commercial Corrosion Inhibiting Admixtures for Reinforced Concrete
This report conveys the results of a three-part laboratory study of corrosion inhibiting admixtures in concrete. The abstract is available in HTML and the fulltext as PDF (1.4 MB).
Comparison of Concrete Rheometers
Comparison of measurements from five types of concrete rheometers (four of them are commercial available). The aim was to provide data to establish correlations among them.
Fresh Concrete Rheology - Recent Developments
An overview of the tests that are commonly used to measure the rheology of fresh concrete and methods to predict the flow of concrete from either compositon or laboratory tests. Ma…
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.
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…
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 exp…
Ultrasonic non-destructive testing for concrete
Photo and short description of the testing facilities at the National University of Singapore.
Visible Cement Dataset
A collection of three-dimensional data sets of hydrating cement, Plaster of Paris, and common brick material, all obtained using x-ray microtomography at the European Synchrotron R…
