Benefits of using HSBFC
- Reduce the risk of early-age thermal cracking especially in mass concreting;
- Improve the resistance to sulfate and chloride attacks of concrete, especially for marine structures. According to SS EN 197-1, if GGBS/GBBFS replacement is 66% or higher, regardless C3A content in clinker, the blended cement is classified as sulfate resisting cement ;
- Eliminate the risk of damage caused by Alkali-silica Reaction (ASR) in concrete;
- Improve long-term strength development of concrete.
HSBFC possesses other features such as good workability, prolonged slump retention, higher ultimate compressive strength and higher flexural strength. The more aesthetically pleasing appearance of lighter colour in HSBFC concrete can soften the visual impact of large structures.
Typical uses of HSBFC
With the superior characteristics over OPC and conventional Sulfate-resisting cement (SRC), HSBFC is highly recommended for use in the following areas:
- Marine structures
- Basement or sub-structure works
- Dams, reservoirs and hydro-electric projects
- Sewerage treatment plant
- Foundation such as piles in soils containing sulfates/chlorides
- Underground pre-cast/in-situ-placing concrete structures such as tunnels
- Large concrete members such as transfer beams
- Pre-cast sewerage pipes
