Zahra Abdollahnejad

Current Position:
Postdoctoral Researcher

Institution:
University of Connecticut

Discipline:
Civil Engineering

Recognized for: Forward-thinking design and development of green construction materials for buildings. Concrete is responsible for 4-8% of the world’s global carbon dioxide (CO2) emissions. Through her development of specialized mixtures of environmentally-friendly concretes, mortars, and insulating components, Abdollahnejad could significantly reduce the impact of concrete on global warming by 50-90% compared to cementitious compositions, making newly constructed buildings more energy-efficient. Her work is re-shaping how the construction industry uses concrete, creating more sustainable buildings for our future.

Research Summary:

Zahra Abdollahnejad, PhD, is a materials scientist and engineer tackling urgent civil engineering problems with geochemical underpinnings. Her work on green, sustainable construction materials for buildings is quite literally re-shaping the way the construction industry views concrete—a material that is responsible for approximately 4% to 8% of world’s global carbon dioxide (CO2) emissions. Abdollahnejad began her career in architectural conservation, excavating and renovating historic sites and old buildings in Qazvin, Iran. Her work in the conservation of monuments provided her with a unique perspective and has informed her present work on the development of green, sustainable building materials, like concrete.

Abdollahnejad’s work on concrete has proven that greener construction materials can, not only, dramatically enhance the mechanical properties of these materials, but can also be environmentally-friendly. To reduce the impact of concrete on global warming, she developed specialized mixtures of concretes and mortars activated by chemical elements. The mixtures use discarded or recycled waste materials from industrial iron blast furnaces, along with natural fibers like hemp, to not only enhance the strength of the concrete, but also to capture the greenhouse gas CO2 through a process called carbonation, greatly reducing the carbon footprint of concrete by 50-90% compared to cementitious compositions. Abdollahnejad has also developed a novel type of foam insulation material—a concrete-based foam that will make buildings more energy efficient. The foamed concrete is cost-effective as a building material and also non-toxic to the environment. Her work spans a range of problems in civil engineering and her forward-thinking ideas are moving the construction industry onto a more sustainable and eco-friendly path.

Many women do not pursue or persist in science careers, or advance to leadership positions — not because they lack the talent or aspirations, but because they face barriers. The Blavatnik Awards for Young Scientists provides equal opportunity for women and other underrepresented groups in science and engineering, which is a valuable endeavor.
