EFFECTS OF DEICING SALTS ON THE DURABILITY OF CONCRETE INCORPORATING SUPPLEMENTARY CEMENTITIOUS MATERIALS
… mixtures incorporating one of two supplementary cementitious materials (SCMs), slag cement or Class C fly ash, exposed to sodium chloride (NaCl), calcium chloride (CaCl2), or magnesium chloride (MgCl2) is evaluated based on damage due to wetting and drying and scaling, with the goal of …

EFFECT OF CRACK-REDUCING TECHNOLOGIES AND SUPPLEMENTARY CEMENTITIOUS MATERIALS ON SETTLEMENT CRACKING OF PLASTIC CONCRETE AND DURABILITY PERFORMANCE OF HARDENED CONCRETE
… of crack-reducing technologies and supplementary cementitious materials on plastic settlement cracking and the durability of concrete subjected to freezing and thawing were evaluated. The study of settlement cracking included 86 concrete mixtures containing internal curing (IC), a shrinkage …

The Role of Reactive MgO as an Expansive Additive in the Shrinkage Reduction of Concrete
… since the 1970’s. At ~4% addition to the cement by weight, it is much simpler than conventional shrinkage measures and in particular, reduces the quantity of crack control reinforcement used. The mechanism is similar to conventional ettringite-based and lime-based expansive admixture …

Modeling the Time to Corrosion Initiation for Concretes with Mineral Admixtures and/or Corrosion Inhibitors in Chloride-Laden Environments
… manufacturers and of concretes with fly ash, slag cement, and silica fume and a concrete with silica fume and a corrosion inhibitor are presented. The specimens were built to simulate four exposure conditions typical for concrete bridges located in the coastal region or inland where deicing …

Complete stress-strain characteristics of high performance concrete
… chemical and mineral admixtures such as fly ash, slag cement, and silica fume, ground granulated blast furnace slag, as well as air-entraining agents are commonly used in the field construction. It has been found that high perforinance concrete can improve the workability, ultimate strength and …

Abrasion resistance of concrete and the use of high performance concrete for concrete railway crossties
… mixes was developed that utilized different replacement levels of portland cement by silica fume (3%, 7% and 15%), class F fly ash (18%) and slag cement (25% and 43%). These mixes were tested via a variety of standard tests, including shrinkage, permeability, freeze-thaw resistance and compressive …

Crystallization of Synthetic Blast Furnace Slags Pertaining to Heat Recovery
Heat recovery from blast furnace slags is often contradicted by another requirement, to generate amorphous slag for its use in cement production. As both the rate and extent of heat recovery and slag structure are determined by its cooling rate, a relation between the crystallization kinetics and …

Influencia de la composición de distintos hormigones en los mecanismos de transporte de iones agresivos procedentes de medios marinos
… de mar sobre los productos de hidratación del cemento, en especial al sulfato y al magnesio, así como a la corrosión de las armaduras en la presencia de cloruros. Los medios por los cuales los iones penetran en el hormigón son complejos y dependen en gran medida de las condiciones del material, …
