The state also clearly advocates the development of concrete mixing plants, the promotion of ultra-fine grinding of slag and fly ash, and the preparation of cement and high-performance concrete according to market demand. 3.
Application of Hydrothermal Treatment on BF Slag and Waste
Application of Hydrothermal Treatment on BF Slag and Waste Glass for Preparing Lubricant Materials in High Strain Rolling for Ultrafine-grained Steel Production By Shinsuke Sato, Takeshi Yoshikawa, Masashi Nakamoto, Toshihiro Tanaka and Jiro Ikeda
Abstract The initial setting time, fluidity and rheological properties of compound paste systems containing ultra-fine GGBS (UFS) were studied. The replacement of UFS into cement results in fast setting. An increase in the dosage of UFS shortened the initial setting time gradually due to the shortening of the induction period. Under the same UFS dosage, the induction period and initial setting

Immobilization of Ultrafine Metal Nanoparticles to High
Ultrafine metal nanoparticles (UMNPs) have a high surface-to-volume ratio and provide a large number of available active sites per unit area, affording unique catalytic properties. Because of their high surface energy, however, UMNPs tend to aggregate. The immobilization of UMNPs to high-surface-area materials with nanoporous or two-dimensional nanolayer structures can not only control the

Strength and durability of ultra fine slag based high
Aug 10, 2021Cement was replaced with ultra fine slag in different percentages of 5, 10, and 15% to study the compressive strength, porosity, resistances against sulfate attack, sorptivity and chloride ion penetration. The experiments to study compressive strength were conducted for different ages of concrete such as 7, 28, 56, and 90 days.
May 09, 2021Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine
