Building Greener: Oltmans Trials Low-Carbon Concrete Mixes in Real-World Applications

In partnership with National Ready Mix, Oltmans' self-perform division successfully placed a series of low-embodied carbon concrete mixes to showcase their potential for real-world construction applications. The demonstration highlighted both the versatility and performance of sustainable concrete technologies in a range of building scenarios.

The team trialed eight separate mix designs, incorporating innovative combinations such as LC3 Cement, LC3 + Slag, Type 1L, and Type 1L + Slag. These mixes were applied across multiple construction uses, including casting slabs, tilt-up panels, slab-on-grade, and sidewalks.

This effort represents a significant step forward in evaluating low-carbon concrete technologies in the field. By experimenting with diverse mix designs and real construction methods, Oltmans and National Ready Mix are helping the industry move closer to reducing embodied carbon without compromising quality, strength, durability, or efficiency.

Relevant Project Experience:

• The Flex Buildings at Goodman's Eastvale Commerce Center, used a specific type of ready-mix, Vertua® low-carbon concrete, to reduce the industrial project's environmental impact.
• Building 3 of The Park at Live Oak project successfully incorporated low embodied carbon mix designs, primarily utilizing Type 1 PLC (Portland Limestone Cement) powder in construction.
• Successfully implemented on the Be Well Behavioral Health Campus , the concrete slabs poured on the three buildings are rated 131-481 Global Warming Potential (GWP), representing the lowest GWP-rated, self-performed product that Oltmans has poured to date.
