BACKGROUNDUntil end of 1970s large laboratories such as PCA, BCA and CERILH carried out basic work on cementitious materials
Work in universities was fragmented and carried out in small, isolated groups
Duplication, reinventing the wheel, no follow-through
PhD structure: studies limited to 3 years
Current developments largely empirical and incremental
Recognition that situation has to change
Mounting challenge to decrease environmental footprint

INDUSTRY PROFILINGWhy we use concrete?
STRONG AND DURABLEConcrete is used for its strength that actually increases over time, and is not weakened by moisture, mould or pests.
LOCAL AND AFFORDABLEconcrete is less cost effective to produce and remains extremely affordable as all of its raw materials are sourced locally.
FIRE-RESISTANTAs it is naturally fire-resistant, concrete forms a highly effective barrier to fire spread.
21
INDUSTRY PROFILINGWhy we use concrete?
EXCELLENT THERMAL MASSConcrete walls and floors slow the passage of heat, reducing temperature swings, making buildings more energy efficient.
SUSTAINABLEConcrete is a low carbon construction material compared to steel etc. Concrete is made from materials that are abundantly available and can contribute to the circular economy by integrating industrial by- products or waste as raw material. When the structure reaches the end of its useful life, concrete can be recycled.
22
INDUSTRY PROFILINGfrom construction to cement and concrete
The Construction Industry
Largest single economic sector in Europe
About 10% of total GDP in EU
More than 10% of total employment in EU
Construction activities increasing globally
High growth rates in emerging economies (China, India) to build up infrastructure
50% of all materials extracted are used for construction
► ENORMOUS ECONOMICAL, ECOLOGICAL AND SOCIETAL IMPACT
23
INDUSTRY PROFILINGfrom construction to cement and concrete
The Construction Industry
CONCRETE IS:
A readily available raw material
Strong and durable ► it is not weakened by moisture, mould or pests
Local and affordable
Excellent thermal mass ► concrete walls and floors slow the passage of heat
Sustainable ► concrete is made form abundantly available materials and can be re-used or recycled
24
INDUSTRY PROFILINGfrom construction to cement and concrete
The Construction Industry
Concrete is a low carbon constructional material that can be produced anywhere in the world using local resources.
In 2011, global cement production totalled 3.4 billion tonnes
4 out of 5 top cement producers are European■ Lafarge, France■ Holcim, Switzerland■ HeidelbergCement, Germany■ Italcementi, Italy■ Cemex, Mexico
Annual turnover > €65 billion (increasing)
Cement production is estimated to reach over 5 billion tonnes by 2050

ENVIRONMENTAL, ECONOMICAL AND SOCIETAL CHALLENGES:
Reduction of (natural) resource consumption
Increase use of alternative fuels and raw materials
Increase recycling rate
Local markets versus global competition
Competition from other materials (wood, steel)
Lack of well-trained employees (attractiveness)
Reduction of GHG emissions and emission trading
Cement production accounts for about 5% of CO2 emissions► Objective: 20% reduction of CO2 emissions 1990–2010 (Holcim)
27
INDUSTRY PROFILINGfrom construction to cement and concrete
Cement & Emissions
Cement production accounts for 3-8% of global CO2
With the development of emerging economies, cement use is set to double by 2050
Emissions from cement production come from:■ energy use ■ chemical reaction during the production process■ use of electricity in the production process

Cement & Emissions
CaCO3 + heat = CaO + CO2
A simple formula that is responsible for the majority of the emissions in cementproduction.
The emissions per tonne of cement vary from plant to plant but are on average around 760 kg of CO2.

Cement & Emissions
The Emission Paradox
Compared to other building materials concrete has a low carbon footprint, i.e. it emits less CO2 per tonne. And yet, the enormous volumes used mean that concrete production accounts for about 3 - 8 percent of the man-made CO2 emissions worldwide.

Emission Reduction Research
Our research focuses on cement at a nano-scale level: fundamental chemistry and physics. We research ways in which we can:
Reduce or substitute the proportion of limestone in the clinker,
Mix clinker with other materials. Less clinker means less decarbonated limestone, and thus reduced emissions.
Increase the use of waste materials or industrial by-products as a raw material
Change the composition of concrete by using less cement
Extend the life of structures by developing concretes that are more resistant to deterioration

WHY IS IT HARD? OBSTACLES:
Changing the chemical composition of cement affects its properties and performance
Fundamental research is required into cement and concrete that will emit less emissions but will continue to offer required level of performance
Time and the environment will play a critical role

THE RESOURCES OF THE EARTH MEAN
WE DO NOT HAVE A LOT OF OPTIONS!
Only 8 elements constitute >98% of the earth’s crust
Even elements we regard as common are more than 1000 times LESS abundant that the elements found in cement – cost and geographical distribution
The composition of the Earth’s Crust limits the possible chemistries
But the limited range mean we can explore all options

POTENTIALConclusions and looking into the future
IN THE FUTURE SUSTAINABILITY CAN BE INCREASED BY:
Extending the use of current clinker substitutes;
The development of novel, cost-effective supplementary cementitious materialsand alternative clinkers;
Optimising the use of waste materials as substitutes for clinker and fuel; However such developments can only be successful if we can provide the basis in understanding and performance tests for users to have confidence in the many potential solutions
There is no magic bullet solution: sustainability can only come from mastering an increasingly diverse range of cementitious materials
47
POTENTIALNeed for Innovation
HOW CAN R&D HELP TO TACKLE THESE CHALLENGES?
Development of blended cements with strength and durability equal to thatof ordinary Portland cement (OPC)
Maximum utilization of alternative fuels and raw materials (AFR) withoutnegative effect on performance
Development of low energy or alternative binders
Full recycling concepts
Long predictable service life of concrete
