CSRP Demonstration Projects
The following lists the demonstration projects that were planned for the last 3 years of the life of the Centre for Sustainable Resource Processing.
1. Cast in-situ concrete
Aim: To demonstrate the feasibility of batching, mixing, casting and curing cast in-situ geopolymer concrete using a transit mixer and local waste materials as aggregates, binder and activator.
Industry Participants: Alcoa, Rocla, Main Roads WA, Boral
Research Providers: Curtin University of Technology, CSIRO MSE.
2. Sewer pipe
Aim: To demonstrate the superior acid resistance of geopolymer concrete and its use in sewer infrastructure projects.
Industry Participants: Rocla
Research Providers: CSIRO MSE
3. Bayer residue in geopolymer formation
Aim: To demonstrate the opportunity to include residue products into geopolymer formulations.
Industry Participants: Alcoa, Rocla
Research Providers: Curtin University of Technology
4. High performance geopolymer concrete
Aims:
- To demonstrate the superior strength (compressive, but in particular tensile strength) and superior processability (rapid curing) of geopolymer concretes.
- To demonstrate the commercial feasibility of high performance geopolymer concrete in the compressive strength range of 100 to 300 MPa.
- To demonstrate the use of such concretes in structural elements such as beams and railway sleepers which normally require significant quantities of prestressing steel and large cross-sectional areas.
Industry Participants: Rocla
Research Providers: CSIRO MSE, Curtin University of Technology
5. Mine backfill using geopolymer binders
Aim: To demonstrate that mine wastes can be used as an alternative to OPC in mine backfill operations.
Industry Participants: Orica, Xstrata
Research Providers: Curtin University of Technology
6. Road applications
Aim: To demonstrate the use of waste materials (flyash, slags, red mud, red sands, alkaline solutions, etc) in the construction of highway elements (road bases, kerbing, culverts, lay-by zones, sound barriers, etc).
Industry Participants: Alcoa, Rocla, Main Roads WA
Research Providers: Curtin University of Technology, CSIRO MSE
Future demonstration projects
Future demonstration projects that were planned to become part of this program included:
Mine Infrastructure: To demonstrate the superior acid resistance of geopolymer concretes in acidic mine environments (for use as slabs, bunkers, culverts, roads, tunnel liners, dam walls, etc).
Fire Resistant Building Elements: To demonstrate the superior fire resistance of geopolymer mortars, foams and coatings in such areas as tunnel linings, partition walls, ducts, etc.
Fly ash Beneficiation: To demonstrate that Run-Of-Station ash (ie all flyash and bottom ash) can be benficiated to produce commercially viable concrete materials (aggregates and binders).
Toxic Waste Containment: To demonstrate that geopolymers offer an intermediate option for the solidification and containment of toxic metal wastes.
