LOW CARBON TECHNOLOGY PARTNERSHIP INITIATIVE (LCTPI)

Operate in more than 100 countries

One third global cement production

26 CSI MEMBER COMPANIES AROUND THE WORLD

LCTPi CEMENT: AN AMBITION

Scale-up CO2 emission reductions of the cement sector in the range of 20% to 25%

in 2030 compared to business as usual

‣Enhancing the coverage of the sector’s CO2 and energy database

‣Electric and thermal efficiency

‣Reducing the clinker content in cement

‣Use of alternative fuels and waste

‣Low carbon cement clinkers

‣Avoided emissions

‣Capture, use and store carbon at scale

OUR COMMITMENT: CONTINUE FOSTERING INNOVATION

Argos Center for Innovation

Medellin, COLOMBIA

CASE 1: CAPTURE, USE AND STORE CARBON AT SCALE

MICROALGAE TECHNOLOGY: Capturing the value of CO2

CASE 2: PERVIOUS CONCRETE, LET THE WATER FLOW

• Urban Planning + water cycle • Urban Heat Island Effect (UHIE)

CASE 3: ULTRA HIGH PERFORMANCE CONCRETE (UHPC)

• A versatile material for

multiple applications

• Increased strength 24,000 psi

vs. 3,000 psi• Less embedded CO2 per

unit weight

CASE 4: LOW CARBON CEMENT CLINKERS

• Lower fuel consumption (10%)

• Lower temperature 1300°C (-10%)

• Less limestone requirements on its

formulation.

• Lower CO2 emissions (-30%)

CEMENT (CSA): A new cement for a

sustainable world

CASE 5: REDUCING THE CLINKER CONTENT IN CEMENT

Neutral CO2 cement makes for a very low CO2

concrete without additional emissions
