Abstract: As energy-efficiency standards for buildings become increasingly stringent, using a traditional insulation material often means having to accept increasingly thick layers of insulation in walls, floors, and roofs. In renovation projects, even if it is possible to increase insulation thickness at all, significant aesthetic and functional compromises are often required to fit more insulation on the inside or outside of the building envelope. The article offers an analysis of the use of nanotechnological insulation materials and innovative phase change materials (PCM) in renovation of buildings, illustrating the possibility of integration into the envelope and the benefits achievable in terms of architectural quality, comfort and energy saving, with particular reference to the historic buildings subjected to architectural constraints.

Abstract: Today, high performance concrete can be produced as easily as normal strength concrete. Concretes are expected to have ductile behavior and have compressive strength, as well. In the recent years, in order to have ductile behavior, researchers have started to strengthen concrete using fibers and have done lots of researches. In this study, normal and high strength concrete with steel and polypropylene fiber are produced, the compressive strength and the tensile strength in split of these concrete is investigated and the crack mechanizm of notching samples are examined.
