Construction System

In South Korea, the need for residential modular buildings has highlighted, due to the increase in demand for small housing and the high land price in urban area. Thus, the cruse housing system (CHS) was developed to build high-rise residential buildings. The object of this study is to analyze the characteristics and fabrication processes of CHS residential buildings when the in-fill construction method is adopted. The result of this study showed that there is the potential to utilize the fabrication processes of CHS in-fill construction system to build high-rise modular buildings.

Within this study, attempts were made to characterize the coarse and fine particulate aerosol fractions in urban area of Belgrade and define the inorganic chemical composition of the aerosol fractions. For this purpose, daily deposits of PM10, PM2.5 and PM1 aerosol fractions were collected during spring and autumn sampling periods in 2007 and analyzed for the PM mass concentrations, trace elements and secondary ions. The results obtained in the two campaigns showed average daily mass concentrations of 37 and 44 ?g/m3 for PM10, 22 and 23 ?g/m3 for PM2.5 and 15 and 17 ?g/m3 for the finest particulate matter fraction PM1 with the maximums exceeding the limit values set by the EU air quality regulations. A correlation with the gas-phase ambient air pollutants SO2, NO2 and O3 was found and is discussed. The concentrations of trace elements (Mg, Al, K, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Sb, Ba, Tl, Pb and Th) and secondary ions (NO3 -, SO4 2-, NH4 +, K+, Ca2+ and Na+) determined in the PM10, PM2.5 and PM1 aerosol fractions showed levels and distributions indicating soil and traffic-related sources as the main pollution sources. This study was conducted as the first step of PM assessment in order to point out main air pollution sources and suggest a remedy strategy specific for this region.
