Low Carbon (Low Cost) Cement
Each year, more than 4 billion tonnes of cement are produced, accounting for ~8% of global CO₂ emissions. While common low-carbon approaches—such as supplementary cementitious materials (SCMs), alternative cements, and carbon capture, utilization, and storage (CCUS)—often involve tradeoffs like slower early strength, longer curing, shrinkage risk, higher cost, and supply constraints, CNTs enable low-cost, low-CO₂e concrete with enhanced durability—without these tradeoffs.
With just a small addition — as low as 0.1% by weight of cement — NTeC®-C solutions enables a breakthrough in durability and permeability performance: more than 80% Rapid Chloride Permeability Test (RCPT) reduction, unlocking sustainability, cost advantages, and enhanced reliability.
CHASM is building the world's largest CNT production network through technology licensing and is seeking strategic licensing and commercialization partners to accelerate global adoption.

Our production approach combines proprietary catalyst technology and rotary kiln reactors to deliver low-cost high performance CNTs at industrial scale, supporting broad adoption across the construction industry.
NTeC-C solutions utilize dry dispersion technology to enable safe, uniform incorporation of CNTs as a drop-in additive in cementitious systems.
Enabling Low-Carbon, High-Performance Concrete
Various end-user evaluations validate that NTeC-C CNT additives significantly enhance concrete performance – delivering higher durability and improved corrosion and crack resistance, with over 80% reduction in chloride penetration at just 0.1% dosage. This enables low-CO2, low-clinker mix designs with increased SCM use while maintaining mechanical performance, improving cement efficiency to achieve required strength at lower cost and carbon footprint. NTeC-C solutions are designed for practical drop-in use, with safe, dry dispersion techology for seamless integration into concrete systems.
