During the last decades natural polymers have become more and more frequent to replace traditional inorganic stabilizers in building materials. The purpose of this research is to establish a comparison between the most conventional building material solutions for load-bearing walls and a type of biomaterial. This comparison will focus on load-bearing walls as used in a widespread type of twenti...

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...

Chinese Fuzhuan brick-tea is a unique microbial fermented tea characterized by a period of fungal growth during its manufacturing process. The aim of the present study was to characterize, both physicochemically and microbiologically, traditional industrial production processes of Fuzhuan brick-tea. Fermenting tea samples were collected from the largest manufacturer. Physicochemical analyses sh...

Abstract Brick plays an important role in the construction industry due their excellent properties like compressive strength and durability. From earliest times they were considered factor purpose of building. Considering different types bricks, fly bricks are best recent because resource intensive cost effective. This article provides up-to-date review current studies categorizing these public...

reducing energy consumption and greenhouse gas emissions have become a worldwide necessity. iran has the sixteenth ranking position of global greenhouse gas emissions and its rate of growth is above global average. built environments are responsible for about 40% of energy consumption and it is generally approved that the greatest portion of built environment is dedicated to residential land us...

Quaternary ammonium compounds (QACs) are widely used in disinfection of water, surfaces and instruments as well as in textile, leather and food industries because of their relatively low toxicity, broad antimicrobial spectrum, non-volatility and chemical stability. Due to these advantages, QACs are also used in restoration and can be applied on historical material. The aim of this study was to ...

This paper presents a novel background model for video surveillance—Spatio-Temporal Patch based Background Modeling (STPBM). We use spatio-temporal patches, called bricks, to characterize both the appearance and motion information. Our method is based on the observation that all the background bricks at a given location under all possible lighting conditions lie in a low dimensional background ...

The thermal insulation properties of building walls are critical to the overall energy efficiency and comfort a building. One important factor that can affect these is type bricks used in construction. Bricks vary their geometry coefficient, which impact ability transfer heat through wall. brick its by altering amount air trapped within it surface area available for transfer. Hollow or those wi...

Ceramic brick as a building material is used in many civilizations worldwide. In the case of Historic Center Cuenca (Ecuador), it dates back to colonial times and remains determining factor local identity. However, beyond productive tradition, its technical conditions knowledge, use, conservation are limited. this context, present research resorts analytical techniques characterize raw solid fr...
