WP 8 Life cycle assessment of cost, sustainability, safety and aesthetics

1. WP 8 Life cycle assessment of cost, sustainability, safety and aesthetics Participants: CTU | DTI | ELC | PD | SUP | GS | DTP| DRA| UNC| GR

2. WP8: Life cycle assesment of cost, sustainability, safety and aesthetics Research Partners:DTI, CTU Industrial Partners: PD, SUP, GS, DTP, GR, DRA, UNC, ELC Workpackage Objective: To assess the TailorCrete concept in the life cycle regarding cost, sustainability, safety and aesthetics. The main objective is to compare TailorCrete to the traditional concept.

4. WP8: Lifecycleassesmentofcost, sustainability, safety and aesthetics Life‐Cycle phases  • Pre‐construction phase – design • Raw material production • Construction • Operation and use, maintenance • Demolition

5. WP8: Lifecycleassesmentofcost, sustainability, safety and aesthetics Formwork Construction

6. WP8: Life cycle assesment of cost, sustainability, safety and aesthetics • Such evaluation is a very complex task • Some tasks need not to be analyzed, as their impacts/costs are approximately the same in both approaches (design, demolition) • The focus is on differences between traditional and TailorCrete approaches

7. T8.1 Life Cycle Cost Task  objective: To compare costs between the traditional process and the TC for a specific construction project. Representative structure (ML 8.1) BenidormWall Particular section Extrapolated drawings

8. T8.1 Life Cycle Cost • Traditional and TC processes: construction phase decomposition • Identification of partners to provide data. • Continuous process to gather information of the construction process in terms of costs, resources, etc. • Identification of tasks which do not need cost analyzed since they cost the same (or with negligible differences) both in the traditional process or in the TC process.

9.

10. T8.2 Life Cycle Analysis • Task  objective: • To asses sustainability of TailorCrete concept, evaluate product’s energy use, and environmental carbon , water, and waste footprints. • The same representative considered: Section of Benidorm wall • Prepared extensive LCA data sheet for the partners to fill out. • Continuous process to gather information of the construction process of the Benidorm Wall (CAD files, Costs, Materials, Resources and construction processes followed). • GaBi software evaluated, facilitating investigation and comparison of environmental impacts of a process, material or building work. • LCA Database with the cost, energy and environmental impact data

11. T8.3 Safety in the life cycle • Task  objective: • To make sure that TC concept will not worsen existing safety concerns. Existing safety issues should be improved, if possible. • Developed material data sheets and safety questionnaire • The open literature and project materials reviewed (DLs, Reports) • Currently data analysis under progress to identify possible safety issues and to propose possible solutions.

12. T8.3 Safety in the life cycle • Material data sheet • Document with information on the potential hazards (health, fire, reactivity, and environmental) of any material • Including description on composition, handling , and work safety of the product • Example: Wax • Not a new material, but its processing requires melting -> possible risk for workers -> protective gear recommended. The electronic version of this questionnaire can be downloaded from http://mech.fsv.cvut.cz/TC

13. T8.3 Safety in the life cycle • Safety questionnaire • Structured according to individual life cycle phases • Focused on identification of new safety issues during individual phases. • Recommendations to how possible or existing safety problems can be eliminated. • Collected results (6 partners contributed) Example: Fibers • Service life: -> improvement of safety (improved ductility - earthquakes, polypropylene fibers - spalling prevention) • Production: need for quality control (dosage) -> solved for steel fibers, still open for polypropylene The electronic version of this questionnaire can be downloaded from http://mech.fsv.cvut.cz/TC

14. T8.4 Aesthetic evaluation • Task objective: • To assess the aesthetic factors (smoothness, texture, surface deterioration) using accelerated tests • Accelerated testing allows to simulate in a short period time the expected performance of cement specimens exposed to different environmental conditions. • 11 samples for accelerated aesthetic evaluation have been received from project partners • Concrete tiles of eleven different conventional or SCC recipes have been casted following the same procedure in different laboratories with similar hydration time • Carried out colour measurements during a preliminary conditioning period

15. T8.4 Accelerated testing • Due to delays in delivery of some samples, the completion of the accelerated ageing tests will have been postponed 2 months • A draft of DL8.4 will be prepared for 31st of January 2013 with the preliminary results and conclusions from the accelerated ageing tests. • The final DL8.4 will be submitted by 1st of April 2013 and uploaded to ECAS.

16. WP8 Future Planning • Tasks 8.1 and 8.2: (LCA+LCC) • Considered postponement of DL8.1 and DL8.2 to perform LCA and LCC directly on demonstrator project. • Higher impact to project • Results more valuable and solid • Task 8.3: (Safety) • Final communication with partners to propose solution on how to improve identified issues • DL 8.3 will be on time. • Task 8.4: (Aesthetics evaluation) • Accelerated testing of received samples and their evaluation in progress.
