Better concrete that doesn't cost the earth.

We boost the performance of your low-performing SCMs, so you can use more of them and lower your cost and carbon per MPa.
Our why
Concrete is the most-used material on earth after water. But the way we make it has to change, because making cement, its binder, creates 8% of global carbon emissions.

Impact
We can boost SCM performance by 15 to 40%, enabling total cement reductions of up to 80%, depending on the material. The result is a lower cost and lower carbon per MPa, with no trade-off on strength.
Solution
Neocrete is a SCM performance booster. Its high surface charge particles activate the dormant pozzolans in low-performing SCMs, so that they match the performance of Portland cement and you can replace more of it.
Problem
Reliable SCMs such as slag and consistent fly ash are becoming scarce and expensive. The low-cost, local alternatives underperform, capping out at 10 to 15% replacement before strength, set and durability fall away. Producers cover the gap with extra cement, which erodes the saving that drive the switch.
Technology
Neocrete is a new kind of additive that boosts the performance of low-cost, abundant, low-performing SCMs so they can replace more cement, with no extra processing.
Molecular activation
Activates dormant cement and pozzolanic molecules, increasing the number of active molecules available for bonding.
Densifying microstructure
Increases the density of molecular bonds.
Reaction acceleration
Accelerates cement hydration and pozzolanic reactions.
Water reduction
Delays early hydration reactions.
