Students from the University of the Philippines (UP) Institute of Civil Engineering won the eco-concrete competition at the American Concrete Innstitute (ACI) Spring 2019 Convention in Quebec, Canada.

Instead of the usual gravel and cement, the group of civil engineering students developed an environmentally friendly concrete composed of recycled, co-product, and locally sourced raw materials that replaced conventional concrete materials.

“Rapid global urbanization boosts the demand for concrete at an unprecedented rate. This means that the environmental footprint of concrete production can no longer be ignored. The conventional concrete mix, which consists only of cement, gravel, sand, and water, must be revisited to achieve environmental sustainability in the decision-making process,” said in a post on its website.

The students only used “locally abundant Diliman tuff as partial replacement to cement and waste glass in making an environmentally friendly concrete.” They won over schools from North and South America, Europe and Asia.

The award-winning entry from Angelica Anne Munar, Ryan Ramelo, Paulo Santos, and Alexis Declaro took home a $750 prize after winning the competition.

(L-R): Engr. Froilan Martillano (ACI Philippines director); Engr. Justin Seranilla (coach); student winners, Angelica Anne Munar, Alexis Declaro, Ryan Ramelo and Paulo Santos; Engr. Christian Orozco (coach and ACI Philippines vice president); Engr. Ramon Allado (ACI Philippines president)

The eco-concrete competition aims to promote the idea of environmental performance in concrete mix design as an important aspect of sustainability.

“Teams thus have the mission to develop an innovative concrete mixture, which will have the lowest possible environmental impacts while maintaining optimal mechanical and durability performances,” it wrote.

The second prize went to the team from the Universidad de Cuenca in Ecuador, while West Pomeranian University of Technology in Poland got the third spot.
