A common challenge as the construction industry intensifies its focus on sustainability has been balancing lower carbon emissions with the need for fast-paced project delivery and Chryso is addressing this issue with a range of products that allows for the use of low-carbon concrete without sacrificing early strength performance.
“Reducing the carbon footprint of buildings is no longer optional it is becoming a priority for developers and specifiers. But traditional methods for lowering embodied carbon such as replacing ordinary Portland cement with supplementary cementitious materials (SCMs) typically slow down early strength development,” says Patrick Flannigan, Chryso GM technical and product support management Africa
This trade-off can cause costly delays on site as slower strength gain means formwork and scaffolding must remain in place longer. It also limits turnaround time in precast manufacturing where production speed is key to profitability.
Chryso’s EnviroMix range effectively resolves this challenge. Designed to support concrete mixes with high SCM content such as fly ash or ground granulated blast furnace slag it ensures that early strength targets are still reliably achieved. This allows for quicker demoulding, formwork removal and overall project momentum without compromising sustainability goals.
“The economic impact of delayed early strength is significant.; Whether it’s slowing down a construction schedule or reducing precast output it affects profitability. “Our products give contractors and manufacturers the ability to keep to their deadlines while using greener materials.”
“With EnviroMix, sustainable concrete no longer means a compromise on productivity or quality. It is a vital step toward greener construction made practical, reliable and economically viable,” Flannigan concludes.
