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 improve the resistance of concrete to attack by acid. [PDF, 1.9 MB]
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.
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]
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 easier.
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.
Accelerating admixtures for concrete - Common accelerators and their effect on cement and concrete.
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.
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]
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.
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).

Wikipedia Articles

Sarajevo Rose - A Sarajevo Rose is a concrete scar caused by a mortar explosion. Mortar rounds landing on concrete create a unique fragmentation pattern that looks almost floral in arrangement.
Parge coat - Parge coat (concrete): A thin coat of a cementitious or polymeric mortar applied to concrete for refinement of the surface. The typical parge coat is 1/32"-1/16" in thickness; this may be less than the minimum thickness allowed by many mortars types.
Slipform stone - A reinforced concrete wall with stone facing in which stones and mortar are built up in courses within reusable slipforms. It is a cross between traditional mortared stone wall and a veneered stone wall.
Noxer block - Noxer blocks are blocks of cement mortar with a 5-7mm thick surface layer of Titanium(IV)oxide (titanium dioxide), which is a heterogeneous catalyst, on it. Titanium(IV) oxide is a photocatalyst that uses sunlight to absorb and render oxides of nitrogen (NO and NO2) harmless by converting them to nitrate ions (NO3-), which are then either washed away by rain or soaked into the concrete to form stable compounds Paved with titanium' an article by Stephanie Makins, Chemistry Review, 2002, Volume 11, Number 2.
Masonry trowel - The Masonry trowel is a hand trowel used in brickwork or stonework for leveling, spreading and shaping mortar or concrete. They come in several shapes and sizes depending on the task.
