3
Aim of workshop

• To create a common understanding of sustainable
  cement, aggregate, concrete and pavement
• To start the work with selecting environmental
  indicators

4
ECO-SERVE Objective

• Reduce the environmental impact of the
  construction industry
• Improve the working environment
• Contribute to growth and wealth by increasing
  productivity, competitiveness and quality

5
Task 2 Objectives

• Establish environmental baseline
• Establish Best Available Technology (BAT)
• Develop environmental indicators
• Develop tools and guidelines for the clusters
• Mapping/identification of players in the
  ECO-SERVE field

6
Definition of an environmentally sustainable
concrete structure

• Designed, built, operated or reused in a
  ressource-efficient manner
• Utilising the inherently environmentally
  beneficial properties
• Tailor-made for the use
• Total environmental impact during the entire life
  cycle reduced to a minimum
• Proposal from Concrete for the environnment - a
  Nordic Network.

7
Criteria

• Use aggregate that is extracted in an
  environmentally sound manner
• Use cement manufactured using modern production
  technology, recycled raw materials and
  alternative energy sources.
• Be produced at concrete plants where
  environmental impact is minimised,
• Have an optimal clinker content according to the
  intended strength and durability.
• Not introduce environmental problems such as
  leaching of heavy metals etc.
• Proposal from Concrete for the environnment - a
  Nordic Network

8
Examples of ways to achieve sustainable concrete
structures

• Use recycled products such as silica fume, fly
  ash and slag etc.
• Use the good durability of concrete to increase
  the service life.
• Use the strength to minimise the total concrete
  volume needed.
• Use the thermal capacity to reduce the energy
  consumption
• Proposal from Concrete for the environnment - a
  Nordic Network

9
About benchmarking

• Benchmarking is to compare with competitors, e.g.
  productivity or energy consumption
• If the company in the bottom can get to the level
  of the company in top, substantial improvents are
  made
• Simple key-parameters are essential

10
Three levels

• RD level
• BAT
• Baseline average

11
Environmental impact of structures dependent on
Demolition and reuse/recycling
Raw materials extraction and processing
Service, repair and maintenance
Construction
Materials production

Task 2 interaction with clusters
Steering committee
Task 2
Cluster 2 Blended cements
Cluster 1 Alternative fuels
Cluster 3 Aggregate/ concrete
Cluster 4 Pavements
13
Task 2 challenges

• To secure network objectives are fulfilled
• To secure a life cycle thinking while the network
  focuses on materials
• To consider national and regional differences
• To develop operational tools
• To co-ordinate between clusters

14
Keywords
Simple
Practical
15
Task 2 in practice

• Prepare guidelines/examples
• Clusters suggest/revise indicators
• Comments from task 2
• Discussion/agreement
• Data collection by clusters
• Calculation /gathering of data

16
Available material

• Note Cleaner Materials Production plus
  Structure
• Slides from presentations today
• Memo to introduce to group work
