The modern level of technological development involves the use traditional materials modified with additives various types and functional purposes, as well composite allowing to obtain a product improved properties. Expanding area application products based on gypsum for facade systems creation weather-resistant, and, first all, waterproof polymers. purpose experiment, results which are present...

Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...

this paper presents a simple methodology for cost estimation of a near optimal heat exchanger network, which comprises mixed materials of construction. intraditional pinch technology and mathematical programming it is usually assumed that all heat exchangers in a network obey a single cost model. this implies that all heat exchangers  in a network are of the same type and use the same materials...

sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. there are many examples of residential buildings in iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...

The research program consists of a series of investigations in the field and in the laboratory. First, four short-span bridges are installed so as to outline the construction-related issues associated with the use of these materials. The bridges are located in a residential area of St. James, Missouri and each bridge utilizes FRP materials in a slightly different way, demonstrating the versatil...

The paper aims to illustrate the relevant use of infrared thermography as a nondestructive, non-contact and real time technique (a) to observe the progressive damage process and failure mechanism of wood, and (b) to detect the occurrence of intrinsic dissipation localization. The investigated parameter is the heat generation due to intrinsic dissipation caused by inelasticity. Thanks to the the...
