Type IL Cement & Strength Performance
Did you know that Type IL cements don’t necessarily have lower strength performance compared to OPC? In fact, many producers are achieving comparable or better performance with PLC, for both early and late-age strength.
The Key?
- Optimising clinker reactivity and kiln burning conditions
- Optimising the milling process conditions and particle size distribution
- Use of performance enhancing grinding additives to enable coarser grinding at comparable strength
- Proper placing, finishing, and curing practices on site
When these factors are optimized, T-IL cements can match or exceed OPC performance across a range of applications.
The effect of specific surface area (Blaine) on concrete strengths (w/cm = 0.49 to 0.51) produced with PLC and OPC from the same cement plant (Thomas et al. 2010)
How Chryso Can Help
Our grinding aids are designed to:
- Improve particle dispersion and hydration kinetics
- Support early strength development
- Enable higher limestone substitution at lower fineness without compromising performance
