CEMENT AGEING AT THE PARTICLE SURFACE
CEMENT AGEING AT THE PARTICLE SURFACE
During storage and handling, cement particles are exposed to moisture and atmospheric CO₂, leading to partial pre-hydration and carbonation at the particle surface. These reactions form thin surface layers that seal reactive clinker sites.
This surface ageing:
Reduces surface energy and wettability
Impairs particle dispersion
Increases water demand
Degrades workability and consistency
As a result, aged cement no longer behaves like fresh cement, despite appearing unchanged in bulk.
QUANTREG™: NANO-REGENERATION OF CEMENT REACTIVITY & WORKABILITY
QUANTREG™: NANO-REGENERATION OF CEMENT REACTIVITY & WORKABILITY
QUANTREG™ is a NANOARC nano-regeneration technology designed to restore cement surface reactivity and intrinsic workability at the nanoscale.
QUANTREG™ operates directly at the cement–water interface, interacting with carbonated and pre-hydrated surface layers to recover effective particle mobility and hydration efficiency.
QUANTREG™ delivers:
QUANTREG™ delivers:
Improved workability without reliance on chemical plasticisers
Enhanced particle separation and dispersion
Restored surface wettability and enhanced hydration for rapid cure and early strength gain
Renewed efficiency of C-S-H nucleation
This allows aged cement to hydrate and flow closer to fresh-cement behaviour, with simplified mix designs.

VALUE FOR INDUSTRY
VALUE FOR INDUSTRY
QUANTREG™ supports NANOARC’s mission to maximise material efficiency and reduce embodied carbon by enabling:
Recovery of performance from stored or aged cement
Reduced additive consumption
Lower material waste and rejection
Greater consistency in concrete production
QUANTREG™ boosts cement reactivity regenerates cement particle surfaces and enhances concrete performance in both new builds and existing infrastructure.
This cement nano-regeneration mechanism enables concrete to exhibit self-healing behaviour that supports repair and long-term durability.
REVIVE CEMENT. RESTORE STRENGTH. REDUCE WASTE
Nano-(Re)generation refers to the use of advanced nanomaterials and nanoscale processes to restore, heal, or enhance the microstructure and properties of deteriorated cementitious materials (e.g., cement and concrete). The aim is to regenerate material performance to enhance the mechanical integrity, durability and service life of ageing infrastructure without full replacement.
Cement naturally loses performance over time during storage, shipment, and handling. QUANTREG™, a NANOARC proprietary nanotechnology, restores cement strength and enhances concrete in one step.
Ultra-low dosage: 0.001 - 0.003 wt %
Effectiveness: Restores ~30 % of remaining potential strength
Form: Stable nanopowder that never expires
Application: Suitable for fresh or aged cement of any age
QUANTREG™ enables sustainable construction, reduces waste, and improves operational efficiency.
WHY CEMENT PERFORMANCE DECLINES
WHY CEMENT PERFORMANCE DECLINES
Cement does not fail suddenly. Its performance gradually declines with age:
0–2 weeks: Minor loss (0–2 %) under controlled storage
2–6 weeks: Early pre-hydration and mild carbonation can reduce strength by 5–10 %
6–12 weeks: Prolonged storage and temperature changes cause 10–20 % loss
3–6 months: Surface passivation and partial hydration reduce performance by 20–35 %
6–12 months: Carbonation and clinker loss cause 40–60 % reduction
Over 12 months: Advanced degradation may reduce cement strength by 60–80 %
Even small performance reductions can impact concrete quality and durability, highlighting the need for regeneration.

AVERAGE Cr (VI) CAPTURE DOSE : 1 gram of QUANTREG CHROME absorbs approx. 50 mg of Cr (VI). Dose varies with the level of Cr(VI) contamination.
APPLICATIONS : Expired cement can contain concentrations of water-soluble hexavalent chromium (Cr(VI)) well above the regulated limit of 2 mg/kg, with some samples showing levels as high as 4.7–25 mg/kg of cement. QUANTREG CHROME is a highly effective nano-sorbent material for the removal of hexavalent chromium (Cr(VI)) through a combination of adsorption and redox reactions, where it reduces Cr(VI) to less toxic trivalent chromium (Cr(III)).
It is effective in shielding Gamma rays, enhances the flexural strength of aggregate in high density concrete for radiation shielding in nuclear power plants, X-ray facilities and uranium mining sites.
It is a high thermal mass material for concrete insulation, High density concrete is efficient in heat retention than standard concrete. This enables it to be used retard hold in solar heat from exteriors (hot climate) or retard solar heat loss from interiors (temperate and cold climates) or as a high emissivity coating to release heat to the environment, when surrounding temperatures drop.
