Comparative study on high-strength structural elements and CNT additions

Carbon Nanotubes (CNT) show extraordinary properties such as high strength and stiffness, the highest among known materials. This is what makes them potential candidates for concrete reinforcement. This paper explores the applicability of CNT in cementitious matrices comparing results derived from h...
