  Understanding the setting behaviours of alkali-activated slag …

  202441 · Ground granulated blast-furnace slag (GGBS) is widely used as supplementary cementitious material of interest for adjusting the performance of concrete. Unlike standard commercial products, characteristics of GGBS from different iron manufacturers vary significantly and assessment of its reactivity, especially at an early …

  (Micro)-structural comparison between geopolymers, alkali …

  200611 · Abstract Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS). Four different …

  Pore solution in alkali-activated slag cement pastes. Relation …

  200411 · Abstract In this work, the relationship between the composition of pore solution in alkali-activated slag cement (AAS) pastes activated with different alkaline activator, and the composition and structure of the main reaction products, has been studied. Pore solution was extracted from hardened AAS pastes.

  Hydration Characteristics and Microstructure of Alkali-Activated Slag ...

  Alkali-activated slag concrete (AASC) is a new green building material. The amount of CO 2 produced by AASC is 1/5th of that produced by ordinary Portland cement concrete (OPCC). In addition, AASC promotes the reuse of slag and other wastes and saves resources. Furthermore, the scope of use of slag has been expanded.

  Hydration and Properties of Slag Cement Activated by Alkali …

  2017413 · The results obtained show that the sulfate is more effective in activating the activity of the slag cement than the other chemical activators. Specimens prepared from calcium sulfate, blast-furnace slag, and ordinary portland cement exhibit better mechanical performance compared to admixtures prepared from other mix ratios.

  Utilization of copper slag waste in alkali-activated metakaolin ...

  2023101 · Abstract. This study aims to evaluate the feasibility for preparing alkali-activated metakaolin (AAM) pervious concrete incorporating copper slag (CS) waste. The effects of replacement of metakaolin with CS on the total void ratio, water permeability, mechanical properties, and abrasive resistance of the pervious concretes were investigated.

  The Effect of Alkaline Activator on Workability and …

  201751 · In this study, experimental results on alkali activated slag (AAS) concrete was assessed to achieve the optimum strength and workability. The alkali contents of Na2O to activate slag in concrete were equal to 3.5, 4.5, 5.5, 6.5 and 7.5 % by mass of slag and silicate moduli of alkali solution varied from 0.45, 0.65, 0.85 and 1.05. The compressive …
