In this study, we discuss about the energy saving in different type of building walls by using optimum insulation thickness with suitable insulation material. The energy saving is maintained by reducing the energy consumption in buildings. Heat losses from building envelope have a major share in waste of energy. So it is essential to save the energy by using optimum insulation thickness. The in...

We analyze a well known type of puzzle in planar geometry: given a planar shape, it is required to find a cut that divides the shape into two identical parts (up to rotation and translation). Clearly not all shapes can be so dissected and for some shapes that appear in puzzles the cutting curve is quite surprising and difficult to find. In this paper we first analyze the inverse problem of asse...

The dynamic identification of a full-scale, two-storey building, made rubble stone masonry, was achieved. Different configurations were analyzed: unstrengthened masonry and retrofitted in both undamaged damaged conditions. Damage accomplished by testing the building under lateral cyclic loading, to reproduce seismic effects. strengthening technique (CRM – Composite Reinforced Mortar) consisted ...

For more than 100 years, the primary theme underlying the NBS/NIST staff contribution to the crystallography of building materials has been the development of an improved understanding of concrete materials performance. Over that time period, portland cement concrete has become one of the most important of our construction materials for roads, buildings, and other large municipal structures. At...

The possibility of using technogenic raw materials – the screening crushed stone with addition cullet based on a silicate binder for production construction structural purposes is studied. By varying processing temperature, it was possible to increase softening coefficient products and achieve pH neutrality their pore liquid. Products processed at temperature 500700 °C have following performanc...
