» 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 influencing it as well as an overview on available test methods (ASTM C1260 and » 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 fulltext is available as PDF (371 kB). » 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. » Concrete with Greater Resistance to Acid and to Biogenic Sulfuric Acid Corrosion
Comparison on the resistance to biogenic sulfuric acid corrosion of mortars based on Portland cement and high-alumina cement. Information about the stresses on the concrete in sewer systems and the formation of sulfuric acid by microorganisms and how to » Curing of High Strength Concrete Using Lightweight Aggregates
Report about tests with prewetted lightweight aggregates as a water supply in high strenght concrete. [PDF, 468 kB] [PDF] » 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. Materials Science of Concrete VI. Proceedings, 2001. » 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 [PDF] » 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. » Methods for Investigation of the Hydration Process in Cementitious Materials
Comparison of results investigating the hydration process in cementitious materials. Methods used are ultrasound, scanning electron microscopy and nuclear magnetic resonance spectroscopy. » 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 met » Optimization of the Mixture of no-fines Lightweight Concrete
Details on the failure mechanisms of the texture and on the effects of aggregates, bonding agents and additives. [PDF] » 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 y » 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 » Technical Dictionary of European Mortars - EMODICO
A compendium of terms and definitions concerning mortar products and their use, available in English, French, German, Spanish and Portuguese. The European Mortar Industry Organization (EMO) prepared this document in order to make technology exchanges easi » Ultrasonic non-destructive testing for concrete
