Solid Waste Management TRIZ Cases

Treating air-quenched steel slag with calcium lignosulfonate and silicon powder improves bonding, moldability, and concrete strength.

This case mixes tire particles passing a 2 mm sieve with dry concrete to reduce pollution and produce durable construction materials.

This case replaces organic binders with a pack-then-react process for faster, lower-impact, more recyclable foundry casting elements.

Blocking agents stabilize aluminous cement mortar for controlled anchoring cure.

Temperature-triggered expansion forms sealing crystals in wellbore cement, helping prevent water seepage and cracking under cyclic stresses.

A slag, fly ash, steel-slag, alkaline-residue, and lithium-battery waste binder tackles organic acids and moisture in mucky soil.

This case combines magnesium oxide cement, natural fibers, and pressure consolidation for uniform density and faster panel production.

A lightweight filler core lowers fiber cement weight for easier handling, while dense outer layers retain strength and water resistance.

Segmented seals, controlled liquid injection, and exhaust control support uniform cement solidification without aerosol diffusion.

C5 cement uses carbonation curing to build strength with less energy.

This case combines timed CO2 carbonation, fraction separation, and washing to remove pollutants and recover concrete-grade aggregates.

Hydrated superabsorbent polymer enables a 0.35–0.50 water:cement ratio, reducing evaporation and improving concrete durability.

This case combines CO2 carbonation with chloride and mineral additives to stabilize IBA and reduce leaching in concrete aggregates.

This case uses sol-gel mixing and additive encapsulation to form geopolymer composites without energy-intensive curing, drying, or milling.

This case combines geopolymer binder, coated cellulose aggregates, and controlled porosity for durable biological growth.

This case addresses cement CO2 emissions and inconsistent geopolymer supplies using local glassy microspheres made by in-flight melting and quenching.

A mixed alkyd and polymer binder slows film formation, extending tile-film removal to 30 minutes while maintaining joint performance.

This case combines hydrothermal treatment with carbonation to improve aggregate reactivity, CO2 uptake, and composite cement strength.

This cement admixture case uses pH activation and polymer thickening to preserve particle dispersion, rheology, and higher additive loading.

Recycled aggregates and CSA cement create lightweight concrete with strength and insulation.

This case balances molten phase, viscosity, and gas release to form porous lightweight aggregates from waste-coal combustion ash.

This dry mortar uses biomass ash with limited cement and additives to meet EN 12004-1 tile adhesive requirements.

Electric pulses separate hydrated paste from aggregate while CO2 enables carbonation.
