Freeze‑thaw resistance of self‑compacting concrete with marble powder & cement kiln dust filler powders and metakaolin

Popis výsledku v původním jazyce

Marble powder (MP) and cement kiln dust (CKD) are important industrial by-products generated in large quantities,nboth with low recycling rates. Contrary to common utilization practices and research trends—such as using MPnin plasters and assessing CKD as a supplementary cementitious material—this paper explores their potential usenas inert fillers in self-compacting concrete (SCC). This approach, especially for CKD, offers more efficient recyclingnroutes without compromising strength or durability. SCC mixtures of low environmental and economic cost werenproduced using MP and CKD as filler powder and metakaolin (MK) as a cement substitute (10% and 20% by mass).nEach composition was evaluated for fresh properties, compressive strength, water permeability, and freeze–thaw (F-T)nresistance. Mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM) were used to interpret thesenphenomena. Although CKD incorporation slightly increased strength, it reduced F-T resistance, while MK improvednstrength, permeability, and micromorphology, enhancing SCC’s durability.
