Our Trojan cements generally contain between 21% and 35% fly ash, (Pulverised Fuel Ash). Our primary product is Trojan T27, which contains 27% fly ash and has been designed to optimise performance in terms of workability and long-term durability, without compromising early strength.
ScotAsh's Trojan cement meets the requirements of BS EN 197-1 for CEM II A/B-V and CEM IV A/B cements. Trojan cements also meet the requirements of BS 6610 and our Trojan T27 meets the requirements of 42.5N cement.
Uses and Benefits
Blended fly ash-based cements can be used in virtually any application where Portland cement would normally be used.
As fly ash is a pozzolana, reacting with free lime liberated from the hydration of Portland cement to form additional cementitious hydrates, it continues to gain strength with time. Trojan cements offer a lower heat of hydration, reduced shrinkage and creep and are resistant to sulfate attack and reduced chloride ingress.
Recommended Construction Uses of Fly Ash Based Blended Cements
Potentially alkali-reactive aggregates
Use with care
In high early strength applications unless hydration is accelerated by increasing temperature
Trojan blended cements are also used for:
- Mortars for the laying and grouting of granite setts in roads and pavements
- As a hydraulic binder in foamed bitumen Macadam
- As cementitious content in grout for mine void filling
- To provide cementitious content in concrete blocks
