“…Different outcomes are seen when comparing the performance of GGBFS 20% and GGBFS 30% in concrete. According to one study, adding GGBFS to concrete at a 20% replacement ratio increased its compressive strength [20]. In two distinct concrete grades, a different study discovered that adding crystalline admixtures and GGBFS at a 30% cement replacement greatly enhanced the concrete's compressive and tensile strengths [21].…”

It is well known that using Ground Granulated Blast Furnace Slag (GGBFS) to replace some of the cement in concrete will cause it to take longer to reach its ideal compressive strength. However, several precast concrete manufacturing processes require high initial compressive strength values to speed up production. The impact of partially substituting GGBFS for cement on the initial strength values of concrete is investigated in this work. The 300 concrete cylinder samples were used to accomplish the study's goals. Compressive and split tensile tests determined the concrete's initial compressive strength and split tensile strength outputs. Therefore, the ideal percentage of GGBFS can replace cement by 20–30% to achieve the desired early compressive strength of 16 MPa in 16 hours by setting the proper water-cement (w/c) ratio at about 0.25. Because a low w/c ratio leads to low workability, some additives, such as silica fume or superplasticizer, can be employed to further increase the workability and performance of concrete.

The durability and strength of concrete in construction can be significantly compromised by permeability issues, which pose considerable challenges to its long-term effectiveness and reliability. By analyzing six selected articles from the Scopus database, this study meticulously synthesizes findings on the effectiveness of CAs in improving these essential properties of concrete. The research meticulously documents and analyzes key variables such as the CA dosage, water–cement ratio, evaluation duration, and treatment conditions, providing a thorough understanding of the factors that influence the performance of CAs in concrete. The results robustly indicate that CAs significantly reduce concrete permeability, thereby enhancing its resistance to water and other detrimental substances, and simultaneously boosts the compressive strength, leading to stronger and more durable concrete structures. However, the study also reveals that the impact of CAs can vary considerably depending on the specific conditions and methodologies employed in the individual studies. This underscores the importance of standardized testing procedures to ensure consistent and comparable results across different studies. This research provides valuable insights for optimizing the use of CAs in concrete formulations, ultimately aiming to improve the durability, performance, and sustainability of concrete in construction applications.
