18. Calcium Aluminate Cements in Context: Comparative Performance for Conventional Concrete Applications

Kimberly Kurtis

Durability

Oral Presentation

Calcium aluminate cements (CACs) are often treated as specialty binders, but recent work suggests their performance merits broader consideration. Drawing on testing funded by the U.S. Federal Highway Administration and recently published in a comprehensive report (FHWA-HRT-24-012), we compare CACs to portland cement, calcium sulfoaluminate (CSA), magnesium phosphate cements, chemically...

27. Ultra-Rapid Hardening Repair Mortar with Amorphous Calcium Aluminates for Freezer Floor Applications at -25°C

Durability

Oral Presentation

Repairing damaged flooring inside commercial freezer warehouses presents significant challenges due to the extremely low temperature conditions, often below -25°C. This study presents the development of a self-leveling, ultra-rapid hardening mortar designed specifically for subzero applications. The binder system is based on amorphous calcium aluminates (ACA), which exhibit high reactivity and...

Durability

Poster Presentation

This paper presents a mathematical model developed to investigate the thermal modeling of calcium aluminate cement (CAC). A control volume is employed to simulate the heat balance behavior in CAC blocks with dimensions of 16 cm × 4 cm × 4 cm. These blocks were exposed to a constant temperature of 1450 °C to analyze the thermal effects during times.

36. Utilization of Granulated Slag as Aggregate and Alumina-Bearing SCM in Cementitious Systems

Ms Kelly Lau (Insight R&D)

Durability

Poster Presentation

This study explores the valorization of a water-granulated platinum slag (GPS) as both a fine aggregate replacement and a supplementary cementitious material (SCM) in mortar formulations. The slag, a byproduct of platinum smelting operations, contains high amorphous content and elevated MgO and Al₂O₃ levels—making it a potential contributor to cement chemistry when properly processed.
The GPS...

10. Comparison of Durability of Calcium Aluminate and Sulphoaluminate Cements (CAC, CSA and HB-CSA) for Aggressive Environment

Durability

Poster Presentation

Concrete made from traditional Portland cement in the sewer system faces severe corrosion. This leads to deterioration of Portland cement, causing a reduction in sewer pipes and an increase in maintenance and repair costs. This research addresses a pertinent issue by evaluating three types of specialty cements: calcium aluminate cement (CAC), calcium sulphoaluminate cement (CSA), and...

41. The durability of CAC compared to Portland cements in cases of biodegradation

Dr Tony Pons (Université Gustave Eiffel)

Durability

Poster Presentation

The biodeterioration of cementitious materials in the wastewater treatment cycle is caused by the biological acid produced by microorganisms. In the case of sewage systems in presence of H2S, sulfuric acid was produced by sulfo-oxidizing bacteria, and in the case of nitrogen pollution treatment in water treatment plants, is nitric acid produced by bacteria. The literature shows that...
