It is mentioned previously that the reactivity of slag is influenced by its fineness of grinding (specific surface area) that is determined by the sizes of slag particles. The finer the slag particles, the larger the surface area, which means higher hydration degree of slag. However, if disregarding the fineness, in other words, take two […]
Granulated Blast Furnace Slag (GGBFS, or GGBFS, or BFS) is the most used material in cement industry to make slag cement. How is GBFS made? What are the processing and its applications? Process: water quenching Generally speaking, GBFS is formed by water quenching. The glassy and granular material is generated when slag is rapidly chilled […]
Although it is somewhat difficult to measure the reaction degree of slag in slag blended cement comparing with the case in Portland cement, many researchers performed experiments on this field. A large body of literature can be found on the kinetics of Portland cement/slag blends. Based on the modification of Takashima’s salicylic acid extraction method, […]
