Trojan Grouts
Trojan general purpose grouts are blends of PFA and Portland cement. Various blends are available, ranging from 1:1 PFA:PC (TGP1) to 20:1 PFA:PC (TGP20), depending on the properties required.
Quality
ScotAsh grouts are manufactured to comply with specifications such as the Civil Engineering Specification for the Water Industry, 5th Edition.
The PFA used in the grouts complies with BS 3892: Part 3 (Latest Revision) Specification for Pulverised Fuel Ash for Use in Cementitious Grouts.
Uses and Benefits
The PFA in Trojan General Purpose Grouts consists of hollow spheres of between 1 and 150mm in size. These form a continuous grading that improves the rheological properties of the grout.
In addition, PFA is a pozzolana and by reacting with the free lime released from the hydration of Portland cement it forms additional cemenitious hydrates, resulting in a denser, less permeable grout.
Some key advantages include:
- Economical - increased volume
- Reduced water to solids ration
- Increasing compressive strength with time
- Reduced bleeding
- Increased yield
- Reduced shrinkage
- Reduced permeability
- Increased resistance to sulfate attack
- Improved flow properties
