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. Can be mixed to Steintec's recommendations for use as a jointing mortar and as a priming/bonding mortar. tuffset G combined with Steintec tuffgrit aggregate produces a high strength gain bedding mortar.


A modular pavement constructed using tuffset G for the bedding mortar, the priming mortar and as the jointing mortar: can be trafficked in three hours.


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 3MPa rather than the requirement of 2MPa), 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.
