tuffset G Specialist Rapid Mortar
Specialist, high-performance multi-purpose mortar with rapid strength gain.
Application
It can be used effectively as a bedding primer and grout, suitable for emergency repairs to modular paving, concrete and filling around gulley and manhole frames where Steintec's 'tuffset 60' has been used for bedding and re-setting ironwork in carriageways.
Description
A high-performance hydraulic mortar with rapid strength gain and enhanced cold weather strength gain characteristics.
Features and benefits:
- Capable of withstanding heavy trafficking within three hours.
- The absence of polymers, chemical admixtures and resin binders allows the mortar to be readily cleaned to avoid residual staining.
- The product meets and exceeds BS 7533 requirements for low elastic modulus, high adhesion bond (achieving 3 N/mm² rather than the requirement of 2 N/mm²), compressive strength and all-round performance.
- Final strength is unaffected by rapid early strength gain, and the stiffness modulus is similar to other products in the Tuffbau range.
- Declaration of Performance (DoP) EN 1504-3: ZA.1a.
For bedding mortar and emergency concrete repair, mix the product with tuffgrit aggregate; otherwise, for bonding and jointing mortar, mix with water.
