Contempra Type GUL Portland Limestone Cement

What if there was an innovative cement that could reduce CO2 emissions by 900,000 tonnes − every year?

Cement and concrete are essential ingredients in building our communities and infrastructure. Engineered for a better tomorrow, Contempra is a contemporary cement that decreases CO2 emissions by 10% while still producing concrete of comparable strength and durability to that produced with regular Portland cement.

With such a reduction in greenhouse gas emissions, Contempra will make a significant contribution to more sustainable construction and cleaner air in Canada. Once adopted for all suitable concrete applications, it is expected to reduce Canada’s greenhouse gas emissions by up to 900,000 tonnes annually.

This is equal to 172,000 fewer cars on the road., or planting 23 million trees.

Contempra makes concrete – already renowned for its safety, sustainability, durability, resiliency, versatility, energy-efficient attributes and contribution to LEED certification – a smarter choice than ever for building stronger communities.



A general-purpose cement suitable for all uses where the special properties of other types are not required. As of late 2014, CSA allows the use of GUL in sulphate environments with the appropriate testing completed.
