Carbon Capture TRIZ Cases
- Precipitated Calcium Carbonate Additive for Low-CO2 Blended Cement
Mineralized CO2 is converted into reactive precipitated calcium carbonate that boosts blended cement strength and lowers embodied emissions.
- Supplementary Cementitious Material Activation for Low-CO2 Concrete
Mechano-thermal activation turns low-reactivity crystalline inputs into SCMs that cut cement CO2 and can improve concrete strength and durability.
- Igneous-Rock Clinker Composition for Low-CO2 Cement Strength
Using igneous rocks instead of limestone removes calcination CO2 while producing hydraulic clinker with strong, acid-resistant cement.
- Mechanochemically Carbonated Clay Filler for Low-CO2 Concrete
Mechanical agitation with CO2 turns clay into an active filler that cuts cement demand, improves concrete strength and durability, and sequesters carbon.
- CO2-Treated Desert Sand Aggregation for Concrete Strength
CO2 treatment roughens and enlarges desert sand grains, then binds them into concrete-grade aggregate while storing carbon.
- Carbonated Supplementary Cementitious Material for Lower-Clinker Cement
Milling mineral particles with over 8% CO2 creates an SCM that captures flue gas, speeds hydration, cuts setting time, and reduces clinker use.
- Cement Clinker Carbonation for Low-Cost Flue Gas CO2 Sequestration
Cement clinker reacts with flue gas CO2 to form calcium carbonate microfibers, cutting capture cost while strengthening cement.
- Multimodal Vaterite Cement Composition for Low-Viscosity Strength
Bimodal and trimodal vaterite particle blends raise packing density and workability while lowering paste viscosity and cement CO2 impact.
- Cement Plant Preheater Gas Extraction for High-CO2 Carbon Capture
This case cools and dedusts CO2-rich preheater exhaust before capture, improving separation efficiency and enabling CO2-lean gas reuse.
- Fluidized Bed Calcination of Clay and Fly Ash for Cement Clinker
Integrating clay and fly ash calcination in a single fluidized bed prevents iron oxidation, eliminating red discoloration while simplifying production.
- Low Ca/Mg Cement Curing with Organic Acids
Low calcium cement reacts with organic acids to form insoluble compounds, enabling curing without CO2-rich atmospheres.
- Composite Curing System with CO2 Gas Control
A curing system manages carbon dioxide concentration and humidity to condition composite materials.
- Electrical Calcination of Metal Carbonates for Cement
Replacing fossil fuel combustion with electrical heating eliminates CO2 emissions from raw material calcination while maintaining required temperatures.
- Two-Step Carbonation Hardening of Hydraulic Cement Concrete
A two-step carbonation method hardens hydraulic cement concrete using controlled CO2 exposure during initial hydration and final curing stages.
- Cement Plant Exhaust Gas Carbonation for CO2 Reduction
Utilizing existing exhaust infrastructure to carbonate waste materials, reducing CO2 emissions without increasing capital expenditures.
- Calcined Clay Limestone Cement Strength Emissions
Composite supplementary material reduces CO2 emissions while maintaining concrete strength.
- CO2-Activated Clinker Binder from MSW Incineration Residues
Transforming municipal solid waste incinerator residues into carbonation-activated clinker binder reduces energy consumption and carbon emissions.
