Excellent fire resistance (FRL up to 180/180/180)
Superior acoustic performance (STC 50-65)
70-80% reduction in explosive spalling under fire
15-25% improvement in carbonation resistance
100+ year service life with proper design
Constraints
15-50 $/m³ premium over standard concrete
Requires Performance Solution pathway under NCC
Engineering certification mandatory
Limited pumping capability at high dosages (>80 kg/m³)
