Entre ellas destaca la llevada a cabo por un equipo del MIT, que ha descubierto que, lejos de tener una configuración solamente cristalina, los hidratos de cemento presentan una condición híbrida, parcialmente amorfa, y que, hipotéticamente, permitiría sustituir por otros materiales la sílice presente hoy en los cementos, dotándolos así de mayor resistencia y flexibilidad, y reduciendo asimismo la cantidad de emisiones de GEI asociadas a su fabricación y vida útil.

Counteracting these impacts at the roots through changes in the composition of the materials may offer an opportunity to moderate the huge carbon footprint produced by construction activity. In the case of reinforced concrete, this possibility depends on some recent studies whose ultimate purpose is to produce cement with a low environmental impact. One of these researches has been undertaken by a Massachusetts Institute of Technology group, which has discovered that cement hydrates are not only crystalline, but have a hybrid, partially amorphous condition. This would hypothetically allow replacing the silica present today in cements with other kinds of materials, giving them greater resistance and flexibility, and furthermore reducing the amount of greenhouse gas emissions that are associated with their manufacturing process and life cycle.
