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] Comparison of Concrete Rheometers : Comparison of measurements from five types of concrete rheometers (four of them are commercial available). The aim was to provide 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 Axim Concrete: AXIM delivers a broad range of admixtures and specialized chemicals that enhance concrete and masonry performance, as well as improve 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 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 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 Methods for Investigation of the Hydration Process in Cementitious Materials: Comparison of results investigating the hydration process in cementitious materials.
