Accelerated Infrastructure Rehabilitation Using Low-Carbon Belitic Calcium Sulfoaluminate (BCSA) Concrete: Recent Advances, Specifications and Prospects
Rapid-setting binders such as Belitic Calcium Sulfoaluminate (BCSA) are increasingly in demand as the need for rehabilitation and fast return to service of roads, bridges, and airport pavement grows. Speed of construction, low shrinkage, and low carbon footprint are the key features of BCSA concrete. The binder was first developed in the United States in the mid-seventies. It allows concrete infrastructure to be replaced and returned to service within hours. BCSA concrete slabs placed at the Seattle International Airport (SEA) in the 1990s are still in service 20 years later and have doubled in strength. BCSA concrete placed on California freeways has tripled in strength in 25 years. The binder also allows innovation in pavement and concrete design. BCSA is also the basis for the design of various rapid-setting performance-engineered concretes, such as Portland-Limestone Cement (PLC) and Limestone Calcined Clay (LC3) concrete with enhanced early strength. This paper reviews recent concrete applications based on BCSA cement and the opportunities they offer in building a more resilient, lower-carbon concrete infrastructure. We also discuss durability and standard specifications.
