Concrete and Concrete Structures: A Review and Directions for Research opens with a chapter by Juan M. Moro, Romina S. Meneses, and Néstor F. Ortega presenting research on recycled concrete in an effort to improve durability. Next, Germán D. Ercolani, Néstor F. Ortega, and Daniel H. Felix examine different methods of crack detection to determine the best course of repair. Rina (Irina) Wasserman discusses a study on alkali-solutions-caused changes in cement pastes and concretes, after which Romina S. Meneses, Juan M. Moro, and Néstor F. Ortega deliberate on research on corrosion in structural elements of reinforced concrete exposed to flexion. Following this, Alireza Joshaghani explores the durability of concrete prepared with sugarcane bagasse ash. Behrouz Behnam investigates the post-earthquake fire resistance of reinforced concrete structures. Continuing, Néstor F. Ortega exhibits results of a study focusing on the performance of reinforced concrete beams exposed to accelerated corrosion. In closing, Alireza Joshaghani studies self-compacting concrete mixtures by using blended binders comprised of sugarcane bagasse ash and rice husk ash.
