摘要：

The use of Ground Granulated Blast Furnace Slag (GGBFS) as binder for concrete had been reviewed extensively in previous reviews. However, the influence of various types of alkali activators on the behavior of GGBFS based concrete had yet to be consolidated in a comprehensive review. Hence, this paper presented a comprehensive review of the effect of various commercial and by-product types of alkali activators on the fresh properties, mechanical properties, and durability of Ground Granulated Blast Furnace Slag-based concrete. Commercial alkali activators prescribed are those hydroxide-based, silicate-based activators, carbonate-based and oxide-based alkali activators. By-product activators can be obtained directly or derived from the industrial by-product. The by-product derived sodium silicate yielded almost similar mechanical properties to GGBS as compared to commercial sodium silicate. Lime kiln dust had similar properties as oxide and carbonate-based alkali activators in alkali activation of alkali-activated materials. (C) 2020 Elsevier Ltd. All rights reserved.
