owing to the proximity of certain locations to the thermal power stations, it has always been efforts of engineers to enhance the flyash utilization rate in various civil engineering constructions adopting suitable strategies. in the present study, a soilflyash interface mechanism has been evolved using different soil-flyash ratios to upgrade significantly stabilization of supporting medium bas...

patients and methods the study was conducted among 40 young rural pregnant women, 12 to 20 years old by implementing a questionnaire during 2012 to 2013 in four villages in southeast of iran. the women were exposed to high-risk factors such as shortage or lack of drinking water, high pressure electric power sources and chemicals released from burning gas both from cooking and cars as a fuel. th...

This study describes an approach for measuring and modelling diffusive and advective transport of radon through building materials. The goal of these measurements and model calculations is to improve our understanding concerning the factors influencing the transport of radon through building materials. To reach this goal, a number of experiments have to be conducted. These experiments, includin...

Innovation in construction materials (CM) implies changing their composition by incorporating raw materials, usually non-traditional ones, which confer the desired characteristics. However, this practice may have unknown risks. This paper discusses the ecotoxicological potential associated with raw and construction materials, and proposes and applies a methodology for the assessment of their ec...

DNA is a promising construction material for the supramolecular 'bottom-up' engineering of artificial nanostructured devices. The use of DNA for the selective positioning of macromolecular components, the fabrication of nanostructured DNA scaffolds, as well as the DNA-templated synthesis of nanometer-sized and mesoscopic complexes, consisting of inorganic and bioorganic compounds, are exciting ...

The building materials that help designers or architects achieve their goal of defining and enclosing space are usually concrete, steel, glass or wood. For these materials designers have both empirical data gained from experience and at times complex calculation methods enabling them to use them in their designs in a tangible, reckonable and, consequently, almost risk-free manner. It seems obvi...

A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, susta...

Global sustainability goals have led to the development of the green building movement. The Green Building Program, stemming from the movement, has had unprecedented success as it provides a quantifi able metric to people’s efforts towards sustainable development. Sustainable development and green buildings are often used interchangeably. Although, sustainable development and green buildings ar...

This study examines the potential reuse of textile effluent treatment plant (ETP) sludge in building materials. The physico-chemical and engineering properties of a composite textile sludge sample from the southern part of India have been studied. The tests were conducted as per Bureau of Indian Standards (BIS) specification codes to evaluate the suitability of the sludge for structural and non...
