Concrete

Innovation Context Typical concrete mix

% by weight Cement 12% Cement production Sand 34% accounts for more than Aggregates 48% 90% of the energy used to make concrete Water 6%

Case Studies Exploration

The Cement Kiln The CO2 Numbers (approximate)

1 tonne cement = 1 tonne CO2

Cement Plant emissions in GVRD : 2 Million t

CO2 Total GVRD: 16 Million t Cement making: 12.5% of GVRD

Cement plant in the World: 1.5 Billion t

CO2 Total World: 20 Billion t Cement making: 8% of world total

1 A Concrete Example The Trend

World +39% CO2 embodied in Asia a high-rise concrete building: 6,000 t +39%

Africa-M-East-Oceania One car 4000 Km = 1 t +23% Production 1995 Mt/a Central South America Equivalent to 24,000,000 Km or Increase 1995-2010 Mt +57% each condo owner lifetime driving. North America +2%

Pacific North West Forest Sink : 840 t / ha Russian Federation +95% 7 ha of forest Europe ( 50 years) +21%

The Proposed Solution The Promises The Challenge

To minimize the GHG signature of concrete Higher strength Slower early strength by maximizing the replacement of Portland cement Lower cost in the concrete mix with SCM (*) Longer life span while maintaining cost, performance, and Better finish constructability

* Supplementary Cementing Material such as fly ash

Higher Strength Lower Cost 60

Flyash is a by-product 50 of coal-fired power plant

40 Production worldwide : 4,000,000 t Flyash Reference 30 US : 60,000,000 t World : 600,000,000 t

20 average use : 10% cost at the plant : 1/10 price of cement cost delivered : 1/2 price of cement 10
