Experimental Study on the Durability of Alkali-Activated Slag Concrete after Freeze-Thaw Cycle

Advances in Materials Science and Engineering, 2021
A freeze-thaw resistance is an important indicator of the durability of alkali-activated slag concrete, which causes structural failure when the performance is low, especially in severely cold areas.

Effect of the activator dose on the compressive strength and accelerated carbonation resistance of alkali silicate-activated slag/metakaolin blended materials [PDF]

, 2015
The effects of activator dose on the properties of alkali-activated slag/metakaolin blends, were studied in fresh and hardened states: heat evolution, strength and accelerated carbonation. High activator concentrations affect the slag dissolution rate,

Using Carbonated BOF Slag Aggregates in Alkali-Activated Concretes [PDF]

Materials, 2019
This experimental study aimed to develop alkali-activated concretes containing carbonated basic oxygen furnace (BOF) slag aggregates. In the first stage, the impacts of replacing normal aggregates with carbonated BOF slag aggregates in different alkali-activated concretes were determined by assessing mechanical properties (compressive and flexural ...

Experimental study on flexural mechanical properties of steel fiber reinforced alkali-activated slag concrete beams

Frontiers in Physics
As an environmentally friendly alternative to ordinary concrete, slag concrete is subject to limitations such as drying shrinkage and micro-cracking during its promotion and application. In order to address these challenges, steel fibers, known for their
