Solid Waste Management TRIZ Cases
- Crack-Resistant UHPC for Water-Rich Strata
Lightweight aggregate provides internal curing to suppress shrinkage cracks in underground engineering.
- Sulfate-Resistant Cement with Fly Ash for Wellbore Integrity
Fly ash combined with low calcium aluminate cement prevents expansive ettringite formation while maintaining mechanical strength.
- Cement Slurry Additive Using Silica and Layered Silicate
A cement slurry additive combines silica with layered silicate to stabilize the mixture.
- Polycarboxylic Acid Copolymer Cement Additive Slump Loss
Composite polymer architecture with polyalkylene glycol ether units prevents slump loss and maintains compressive strength over time.
- UA-HPD Grout for Fast Curing and Stain Resistance
Urethane-acrylic hybrid polymer dispersion grouts solve slow strength development by combining polymer binders with fillers for rapid curing.
- Moss Adhesive with Natural Polymers and Clay Fillers
A composite adhesive uses konjac glucomannan, chitosan, collagen, and clay fillers to bond moss securely.
- Two-Part Thixotropic Slurry for Lost Circulation Sealing
Separate pozzolan and calcium slurries mix in situ to gel, preventing fluid loss from erosion while maintaining pumpability.
- Dry Plaster Mixture with Hollow Glass Microspheres for Sprayable Insulation
A dry plaster mixture uses hollow glass microspheres and calcium sulfoaluminate cement to form a sprayable thermal insulation layer.
- Balling Machine with Reciprocating Scraper for Aggregate Control
Reciprocating scraper creates controlled ridges inside the rotatable tube, enabling precise ball size control while eliminating separate pre-mixing steps.
- Dry Mortar Composition for Drainage Paving
A dry mortar mixture with hydrophilic fibers and CSA cement reacts with sprayed water to form a permeable, consolidated paved surface.
