This manuscript presents two novel methods of evaluating the adsorption of air-entraining admixtures (AEAs) by coal ashes used in cementitious mixtures. A developed three-phase equilibrium (TPE) method measures fly ash adsorption capacity accounting

Carbon dioxide was investigated for use as a beneficial admixture to concrete as it was truck mixed. The reaction between the CO2 and the hydrating cement creates finely distributed calcium carbonate reaction products that thereby influence the subse

In Brazil, 20% of annual steel production where the furnaces are fueled using charcoal, with growth prospects the increase in the use of charcoal as a substitute for coke. The slags from coal blast furnaces (coke) have a large percentage of CaO, whil

Chloride threshold value is an important input parameter in service life predictions. There has been a need for a reliable method for testing this value in order to improve the understanding of basic factors influencing the corrosion initiation. For

There are many ways to reduce the carbon footprint of concrete including reduction in its portland cement clinker content by methods including: (a) optimization of total aggregate gradations, (b) use of water-reducing admixtures, (c) intergrinding cl

The performance of concrete, in terms of its placeability, physical properties, and its durability, can be enhanced by the use of slag-blended cements or separately added ground granulated blast-furnace slag. It also has advantages for architectural

There is a need to develop a better understanding of the relationship among short-, medium-, and long-term tests to assess the resistance of concrete to chloride penetration. In this contribution, a resistivity-based test is compared to a 90-day salt

To evaluate measures to prevent alkali-silica reaction (ASR) in concrete and to correlate short-term laboratory tests to long-term performance, an outdoor exposure site was established in Kingston, ON, Canada, in 1991. Alkali-silica reactive aggregat

Sulfate attack comprises a series of chemical reactions between sulfate ions and the components of hardened concrete. As these reactions may lead to cracking, spalling or strength loss of concrete structures, appropriate test methods are needed to de
