Renderoc HB70 Plus
High strength, high build, high resistivity, shrinkage compensated repair mortar conforming to EN1504-3 Class R4.
Uses
For the reinstatement of concrete where low permeability, high
compressive strength and high resistivity characteristics are
key requirements.
Renderoc HB70 Plus has been specifically developed for
vertical and overhead repair work, where it’s lighter weight
nature and high build characteristics make it ideal.
Renderoc HB70 Plus achieves 70 MPa @ 56 days. If lower
compressive strength is required for compatibility with host
concrete, Renderoc HB40 Plus should be considered.
Renderoc HB70 Plus is not suitable for repairs where
Galvashield anodes are being used – Renderoc HB70 should
be considered.
Description
Renderoc HB70 Plus, a concrete repair mortar, is supplied as
a ready-to-use blend of dry powders that requires only the
site addition of clean water to produce a highly consistent,
high-strength repair mortar.
The material is based on the latest advances in cement, fillers
and chemical additives technology, and is polymer modified
to provide a mortar with good handling characteristics, while
minimising water demand.
The hardened product exhibits excellent thermal compatibility
with concrete and outstanding water repellent properties. The
low water requirement ensures fast strength gain and long-term
durability.
Advantages
- Compatible with concrete strength > 45 MPa
- High strength – suitable for structural repairs
- Abrasion-resistant – suitable for aggressive
environments - Shrinkage compensated – provides long-term
dimensional stability - Low permeability to potentially damaging water, CO2 and chloride ions
- High build formulation – fewer applications of product
- High resistivity – provides increased durability
- Excellent bond to SSD concrete substrates – no
separate primer required in most circumstances – refer
to the Substrate Priming section - 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 - Sustainable product with lower carbon footprint –
formulation based on supplementary cementitious
materials - Complies with EN 1504-3 Class R4
