Toggle navigation Dr David Stone works on a small domed building made with Ferrock, a material he has been developing as an alternative to Portland cement Collaborative venture between Iron Shell LLC of US and VIT Chennai ANI | Updated: Dec 24, 2020 13:44 IST New Delhi [India], December 24 (ANI/SRV Media): A new green alternative to Portland cement will be studied and developed in the Concrete Technology and Structures Laboratory at VIT Chennai. The innovative cement is called Ferrock because it is an iron-based material and becomes hard like a rock when it reacts with carbon dioxide. This greenhouse gas is trapped in the material making it carbon negative. In contrast, the manufacture of Portland cement is a huge source of CO2 and contributes about 8 per cent to the total global output.
