slag cement
Quick Summary
Slag cement is a type of pozzolana cement that uses slag as its pozzolana material. Portland blast-furnace slag cement is produced by grinding together portland cement clinker and granulated blast-furnace slag in varying proportions.12
Slag cements are similar in properties to portland cement but have lower lime and higher silica and alumina content. Cements with higher slag content exhibit improved resistance to chemical attack. Another type, supersulfated cement, contains granulated slag mixed with gypsum or anhydrite and a small amount of portland cement. This also offers increased resistance to chemical attack. Pozzolanic cements are mixtures of portland cement and a pozzolanic material, which can be natural (like volcanic materials) or artificial (like fly ash or burned clays). Pozzolanas react with lime in the presence of water to create cementitious compounds.3
