What’s on the Inside
Matters
The Science Behind the Sustainability
We must be mindful with our construction. Concrete is the second most-used material on earth. With Gunlakeโs BlueStar Low Carbon Concrete range you can adapt your construction approach and replace energy-intensive cement with supplementary cementitious materials (SCMs) like fly ash and blast furnace slag. These recycled industrial by-products reduce the carbon footprint of each mix while enhancing long-term durability.
For projects seeking full carbon neutrality, BlueStar Zero offsets remaining emissions through trusted, audited initiativesโfrom reforestation in Australia to clean energy access overseas.
Options for Sustainability
and Flexibility
Three Tiers. Infinite Possibilities.
The BlueStar Low Carbon Concrete range is a system designed for flexibility. Many of Gunlake concrete mixes can be made available in one of three BlueStar categories, providing a proven selection to meet your projectโs sustainability goals without compromising performance requirements.
Whether youโre targeting Green Star certification, striving for internal ESG benchmarks, or simply looking to lower your environmental impactโGunlake BlueStar Low Carbon Concrete products can be tailored to your sustainability goals.
Each mix is engineered to maintain the industry-standard 28-day strength.
