Top 10 Ways to Reduce Concrete's Carbon Footprint

 

DOWNLOAD PRESENTATION

Concrete is the building block of modern society and the most widely used building material. Nearly every structure built today, including buildings, bridges, homes, and infrastructure uses concrete in some way. It provides us with shelter along with places to work, learn and play. It connects us through roads and rapid transit and airports. Water is delivered and treated in concrete structures. Concrete is economical, available everywhere, durable, and versatile. As demand for building construction continues to increase, it is likely the demand for concrete will also increase. Like all building products, however, concrete has a carbon footprint. This presentation will analyze the top ten strategies to take advantage of concrete’s benefits while ensuring the lowest possible carbon footprint.

​The Economic and Environmental Value of Stronger, More Resilient Construction

DOWNLOAD PRESENTATION

The past decade has made it clear that our built environment – buildings and infrastructure – is not prepared for 21st century natural hazards. Since 2012, the United States has averaged fifteen weather-related events – hurricanes, floods, wildfires – with damages in excess of $1 billion dollars. The MIT CSHub has been carrying out research to better estimate both the risks posed by natural hazards to the built environment and the economic and environmental value of mitigation solutions. This presentation will review work that has comprehensively analyzed hurricane risks to residential buildings throughout the US East and Gulf Coasts. Our work has shown that current models undervalue stronger construction in nearly all coastal communities. For some states, this undervaluation exceeds a billion dollars per year. Using these same models, we will also review the environmental impacts, especially the embodied materials impacts, of hazard-susceptible vs hazard-resistant construction.

Comparative Resilience Benefits of Concrete Construction

DOWNLOAD PRESENTATION

 

Modern building codes do a good job of ensuring that buildings will be safe following a major natural disaster, regardless of their construction material. But that doesn’t mean all materials perform equally. The US Resiliency Council, through a grant from the RMC Research & Education Foundation, studied the performance of a common, four-story apartment building under hypothetical earthquake scenarios in three US cities, when constructed of Insulated Concrete Forms, traditional wood stick framing, CLT, and hot rolled steel framing. The study indicated that the performance of stiffer materials such as concrete result in higher performance, both in terms of repair costs and recovery time, and yield a positive ROI when compared to the cost of construction.

Biochar Concrete: Carbon Reduction, Mechanical Enhancement and Commercial Viability

DOWNLOAD PRESENTATION

In the past 10 years, development in the field of biochar concrete has seen several important milestones through the efforts of an international community of researchers and practitioners. Significant progress has been made on the understanding of the mechanisms by which biochar enhances various mechanical properties of concrete. The capability of biochar concrete under extreme operational conditions was also experimental demonstrated; for example, biochar concrete was shown to be able to resist ingress of chloride and sulfate ions better than normal concrete, thus paving the way for utilizing it for marine applications or in seawalls to protect coasts from sea-level rises in the future. After a summary of these progresses, this talk will reflect on the commercial viability of biochar concrete, from a life cycle systemic perspective. This perspective will also make a case for the need to develop a holistic industrial symbiosis network and circular economy consisting of waste recycling, biochar production and multi-pronged cascading applications of biochar.
