Renderoc HB40

Shrinkage compensated repair mortar for concrete strengths of 30-45 MPa
suitable for use with embedded
galvanic anodes

Description

Renderoc HB40 concrete reinstatement mortar is supplied as
a ready to use blend of dry powders which requires only the
site addition of clean water to produce a highly consistent,
medium-weight repair mortar. It is based on Portland cements,
graded aggregates, lightweight fillers and chemical additives
which provide a mortar with good handling characteristics
while minimising water demand. The low water requirement
ensures good strength gain and long-term durability.

Uses

For the reinstatement of large areas of reinforced concrete
where low permeability and low shrinkage characteristics are
required, and where higher compressive strength is an important
consideration.

Renderoc HB40 has been engineered for the repair of columns
and beams. Its relatively low fresh wet density makes it also
suitable for soffits and other overhead repair work. The mortar
can also be used for small, localised patch repairs.

Where compatibility with lower-strength concrete is required,
but low permeability and high-build characteristics are
important, Renderoc HB25 should be used. For higher strengths
Renderoc HB70 should be used.

Renderoc HB40 is suitable for use with Galvashield XP incipient
anode protection and the Cathodic Protection system. Contact
Fosroc for further details.

Advantages

• Compatible with concrete strength in the range 30 to 45MPa.
• Abrasion resistant – suitable for aggressive environments.
• Shrinkage compensated – provides long-term dimensional stability.
• Low permeability to potentially damaging water, CO2 and chloride ions.
• Suitable for use with Galvashield anodes.
• Can be applied using a wet-spray process – providing faster high-build repairs.
• Pre-bagged to overcome site-batched variations – only the site addition of clean water required.
• Complies to AS/NZS4020:2005 – suitable for use in potable water.
