Reduce carbon, increase performance
Neocrete's additive activates cement and cementitious materials (including natural and industrial pozzolans), adding workability and durability to concrete, and strength at all ages.
​
Neocrete's new generation additive will be available for pilot projects from May 2024. We are now accepting expressions of interest for commercial projects commencing in 2025.
Reduce cement and embodied carbon
​
Accelerate setting time and increase strength
Make concrete more durable and watertight
​
Improve self-healing of microcracks
​
​
Reduce cement content and carbon footprint
Neocrete's additive activator is added at just 2-4% of cementitious materials.
This enables a reduction of cement by up to 40% when used with natural pozzolans (volcanic ash) and 50% when used with industrial pozzolans - with no loss in strength at any age.
​
Our R&D programme is on track to create carbon neutral concrete by 2027, with no loss in strength and with greater durability than conventional concrete.

Increase strength
Neocrete Activator accelerates the strength setting of concrete. Independent testing shows an increase in day 1 strength of 70-140% and significantly earlier achievement of 28 day strength.
​
This is why D5 Green, our previous generation activator, was chosen for projects where developers needed to considerably decrease the period of construction or remove formworks early.
​
The new generation additive activator, made in New Zealand, is more potent and efficient than previous generations, and achieves higher early and ultimate strength.

Make concrete more durable and watertight
Neocrete's additive creates concrete with a tighter microstructutre. This makes is watertight and resistant to seawater - critical in a world increasingly impacted by floods, rising sea levels and other impacts of climate change.
​
Neocrete's previous generation activator D5 Green is BRANZ appraised for enhanced durability and water tightness.

Improved self-healing microcracks
Neocrete, just like Roman concrete, self-heals microcracks.
If through cracks (up to 0.5mm) appear in Neocrete due to external impacts, and water enters these cracks, Neocrete will self-heal without human intervention. This property has been achieved in the lab, and small scale trials, but is yet to be independently assessed by a certifying body.
