Ultragreen™ uses by-products from other manufacturing industry such as fly ash and slag, at a 50% cement replacement. This reduces the overall environmental impact of these industry waste by-products, and reduces the overall carbon footprint of the concrete. Lafarge utilizes Portland Limestone Cement, which results in a 10% reduction in carbon dioxide emissions as compared to regular portland general-use cement.
To minimize our impact on water resources, Lafarge reduces the amount of fresh water consumption by incorporating a percentage of reclaimed water to the concrete. Regular quality control testing ensures there is no impact to the concrete's fresh and hardened properties.
In some Lafarge locations, Ultragreen™ products 30MPa and below contain 20% recycled aggregate, produced from Lafarge’s internal returned concrete and is manufactured right at the plant. This reduces our consumption of natural aggregates and reduces our carbon footprint by eliminating a percentage of the transportation of natural aggregates from source manufacturing gravel pits.
