Worldwide concrete is the most widely consumed civil construction material regarding its versatility, strength, and durability, among other benefits. Concrete is used in almost every type of construction, including homes, buildings, roads, bridges, airports, and tunnels. However, the environmental impacts of cement (and thus concrete) production are significant, considering a mean value of 0.948 kg CO2/kg Ordinary Portland Cement (OPC) for the life cycle CO2 footprint of OPC. According to The Global CO2 Initiative (2016) research revealed that significant progress in CO2U has been made in the past five years (2011-16), with many technologies shown to be scalable. Momentum is favorable for four major markets – building materials, chemical intermediates, fuels and polymers.

To become more sustainable, the concrete industry also uses industrial waste by-products such as fly ash (from coal combustion) and blast furnace slag (from iron manufacture) to constitute a portion of the cement used in producing concrete. Additionally, the incorporation of solid wastes, such as construction & demolition and tyre rubber to replace natural aggregate are eco-friendly alternatives.

Green concrete is defined as concrete that uses waste material as at least one of its components, requires less amount of energy for manufacture and, compared to conventional concrete, produces less carbon dioxide. However, the climate benefit of a CO2U (carbon dioxide utilization) product depends not only on how much CO2 the product contains but also the amount of CO2 emitted in making the product.

The construction engineering industry is a leader in innovating sustainable practice to address the UN sustainable development goal, and this webinar discusses the technologies that can support engineers, architects, and construction professionals seeking efficient, advanced solutions that conserve non-renewable resources and reduce carbon dioxide emissions. Dr. Ana Evangelista has been investigating the properties of recycled concrete and eco-friendly building materials. She will present the potential alternatives to design a durable and eco-friendly concrete mix.

3 key takeaways from this webinar:

• Overview of Construction Engineering sector and UN sustainable development goals (SDG)
• Alternatives to mitigate CO2 emissions in the manufacturing process of concrete
• A recent trend in research and commercial interests in carbon capture concrete is that of the CO2 consumed during the curing and mixing of concrete
