Calcium aluminate cements - Wikipedia

Calcium aluminate cements (CAC) are often used in coination with calcium sulfate and Portland cement for special appliions where rapid setting, rapid drying and shrinkage compensation are required. A growing fraction of the clinker, which has the highest CO2 intensity, is being replaced by supplementary cementitious materials (SCM). These SCM are usually from industrial by-products …

Materials | Free Full-Text | Steel Corrosion Behavior of Reinforced Calcium Aluminate Cement …

Mineral additions can eliminate the conversion in calcium aluminate hydrates and thus inhibit the future strength retraction of calcium aluminate cement (CAC). However, the impacts of these additions on the protection capacity of CAC concrete in relation to the corrosion of eedded steel reinforcement remains unclear. This paper focused on the corrosion behavior of steel reinforcement in slag
