Fly ash vs ggbs
WebApr 14, 2024 · The fly ash (FA) used was low-calcium fly ash obtained from the Gongyi Yuanheng Water Purification Material Plant, with a specific surface area of 368 m 2 /kg. The ground granulated blast furnace slag (GGBS) was obtained from Henan Yuanheng Environmental Protection Engineering Co., Ltd., with a specific surface area of 412 m 2 /kg. WebFrom structural point of view, GGBS replacement enhances lower heat of hydration, higher durability and higher resistance to sulphate and chloride attack when compared with normal ordinary concrete. On the other hand, it also contributes to environmental protection because it minimizes the use of cement during the production of concrete.
