My name is Mateo, I am a Civil Engineer graduated in Ecuador, South America. I am 27 years old, I published an article in the ACI called: "Influence of Recycled Expanded Polystyrene for Sustainable Structural Concrete". I did my specialty in University Teaching and I am doing a Master's Degree in Seismic Resistant Structures. I love collaborating in technological advances and new engineering discoveries. A hug to all.
