However, the mixture of the aggregate with the cement paste creates one of the most vulnerable areas of concrete, the interface of aggregate and cement paste. The judicious application of nanoporous thin films (NPTFs) on the aggregate’s surface is an effective way to improve those interfaces. The most recent work on concrete shows that the use of different types of NPTF can induce changes in different properties of concrete or in an aggregate’s mineralogy. In particular, the observed changes in mechanical properties such as compressive, flexural, and tensile strengths; modulus of elasticity; and drying shrinkage can ameliorate longitudinal and transverse cracking, corner breaks, punchouts, and D-cracking. Several mechanisms are proposed to explain the changes observed in concrete and the implications for its ultimate performance. These new results open doors for new applications of NPTFs and indicate possible future research in this field.
