Compressive Creep of Prestressed Concrete Mixtures With and Without Mineral Admixtures
Concrete experiences volume changes throughout its service life. When loaded, concrete experiences an instantaneous recoverable elastic deformation and a slow inelastic deformation called creep. Creep of concrete is composed of two components, basic creep, or deformation under load without moisture …

Modeling the Time to Corrosion Initiation for Concretes with Mineral Admixtures and/or Corrosion Inhibitors in Chloride-Laden Environments
The application of a mineral admixture, or a corrosion inhibitor, or a combination of both are methods used for the corrosion protection for reinforced concrete bridges. The results of a study on evaluation of corrosion inhibitors from three different manufacturers and of concretes with fly ash, …

Carbonation and permeability characteristics of modern South African concretes
… The construction industry has introduced mineral admixtures as partial replacement of PC in the attempt to mitigate the negative environmental impact of cement production. The use of mineral admixtures has positive economic and environmental benefits. In the context of concrete durability, …

Monitoring Early Age Cementitious Materials Using Ultrasonic Guided Waves
… ratios (w/c = 0.40, 0.50, and 0.60), chemical admixtures (accelerant and retardant), mineral admixtures (silica fume and fly ash), and coarse aggregate (pea gravel). The time of setting and compressive strength of the various mixtures was determined in accordance with ASTM standards. …

Early-age hydration and volume change of calcium sulfoaluminate cement-based binders
… binders. For the first time, interaction between mineral admixtures (Class F fly ash, Class C fly ash, and silica fume) and OPC-CSA binder was studied. Various physico-chemical factors such as the hydration of ye’elimite (main component in CSA cement), amount of ettringite (the main phase …

Complete stress-strain characteristics of high performance concrete
… such a better quality of 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 …

Examination of the forensic engineering techniques employed on fire-damaged concrete structures
… and these ‘blended cements’ typically involve mineral admixtures such as ground granulated blast-furnace slag (GGBS), fly ash (FA) and silica fume (SF). The percentage of PC replaced in these concrete mixtures varies depending on the type of cement and design criteria as well as other related …
