Effect of Aggregate Size Distribution on Concrete Compressive Strength
Corresponding Author : M. B. Haque (bashir-cee@sust.edu)
Abstract :
Effects of size distribution of both fine and coarse aggregate and maximum coarse aggregate size on concrete compressive strength were analyzed. Other variables like water cement ratio, aggregate cement ratios were kept constant and only 28 days compressive strength was measured to evaluate the result. Mixtures of Sylhet sand and local sand were used as fine aggregate and stone chips were used as coarse aggregate. Twelve set of cylinders were crushed with different combination of fine aggregate having fineness modulus…
Impact on sustainability of Hail Haor by integrated water management activities
Corresponding Author : Md. Misbah Uddin (mun_cee@yahoo.com.uk)
Abstract :
This study concerns with the activities running through the projects under different wellknown institutions and the effects of the projects on sustainability of the environment of Hail haor. Hail haor is the main water reservoir of Moulobhi bazar-Sreemangal area. Hundreds of Choras (small canals in hilly area which carries water) discharge water in this haor. Huge amount of water also carries tones of sediments. This causes siltation of the haor as well as the Choras. As the depth of the…
Influence of Weather Parameters on Red Spider Mite- A Major Pest of Tea in Bangladesh
Corresponding Author : M. Ahmed (hoquemm@gmail.com)
Abstract :
An investigation was carried out at the main farm of Bangladesh Tea Research Institute (BTRI), Srimangal, Moulvibazar, Bangladesh during 2005-2009 to find out the influence of weather parameters on the infestation of red spider mite in Bangladesh tea. Monthly data on mite population and infestation were recorded from the experimental plots with systematic sampling method. Five years meteorological data of the experimental area under the Srimangal Meteorology Station were also collected for the study from the Meteorological Department, Dhaka. The…
Integrated Filtration System for Iron-Free Water in Small Public Buildings
Corresponding Author : M. A. Islam (msaamin-cep@sust.edu)
Abstract :
An integrated filtration system has been developed for drinking and washing purposes. This is a bench scale unit made of locally available low-cost materials. The unit can remove iron and bacteria, and produce household water maintaining the accepted standard. The operation and maintenance of the plant is simple and could be done by unskilled labor. Based on the experimental results, techno-economical evaluation has also been done for a large-scale plant. The academic building ‘B’ of SUST is selected as a…
Redesigning Cycle Rickshaw Wheel using QFD Technique to Minimize Accident Probability and Severity
Corresponding Author : K. Nahar (mosharraf80@yahoo.com)
Abstract :
This paper reviews the possible problem areas of non-motorized means of travel in Rajshahi city, particularly cycle rickshaw, with respect to the view of rickshaw pullers and passengers; and severity analysis. Accidents are more frequent now a day mainly caused by lack of rickshaw pullers’ adequate training and design of rear wheels; according to market analysis and reviews. Violent accidents are occurred while the rickshaws drive beside one another and it is observed that they made collisions and ultimately accident…
Renewable Energy Systems for Newly Constructed Residential Buildings in Dhaka: Barriers and Probable
Corresponding Author : Md. Mostafizur Rahman (mostafiz-arc@sust.edu)
Abstract :
Energy is essential to ensure quality of life and to underpin most of the services to our environment. Bangladesh faces unprecedented energy crisis due to high-energy demand and poor management. Low production results frequent disconnection; load shedding and most of the service sectors in the city are interrupted. Surprisingly residential sector consumes 45% electricity of Dhaka and the demand is increasing day by day. Another problem is that government introduced new satellite towns to keep pace of development and to…
The Trends of Environment Friendly Product Design in Bangladesh

Abstract :
Environmental awareness continues to rise, and customers of all types are realizing the importance of eco-friendly products which are essential to protect our planet. Eco-designer creates designs that are demanded by markets. Green design rules are needed to support the implementation of environmental features in the practical design situation. Green design or Design for Environment (DfE) is a field of product design methodology that includes tools, methods and principles to help designers reduce environmental impact. The main objective of this…
Trends of Climatic Variables (Rainfall and Temperature) at Sylhet, Bangladesh
Corresponding Author : A.F.M. Kamal Chowdhury (aic_cee@sust.edu)
Abstract :
The study has evaluated long-term changes and trends in certain climatic variables such as rainfall and temperature at Sylhet. The data has been collected from Bangladesh Meteorological Department (BMD) and Climate Change Cell of the Department of Environment. For convenience of analysis, the available rainfall data (1960-2010) were divided into two halves 1960-1985 and 1986-2010 as well as temperature data (1948-2010) into 1948-2010 and 1980-2010. The rainfalls during the summer, critical period and monsoon are found to have an increasing…
Deposition and Characterization of p-Cu2O Thin Films
Corresponding Author : M. Rasadujjaman (rana1phyru@gmail.com)
Abstract :
In this work we have studied the p-type cuprous oxide (Cu2O) thin film fabricated with thermal oxidation and spray pyrolysis techniques. Cuprous oxide layer was prepared by thermal oxidation method inside a furnace in the temperature range of 930°C - 1010°C. X-ray diffraction studies revealed the formation of single phase cubic Cu2O films. The best quality Cu2O films were obtained at 970°C. The electrical resistivity of the Cu2O layer varies with the variation of temperature and found of the order…
Effect of Mn Substitution on the Electric and Magnetic Properties of Nanocrystalline NiMnCu Ferrites
Corresponding Author : S. Nasrin (sharifa_labiba@yahoo.com)
Abstract :
Nanosize powders of NiMnCu ferrites were prepared by combustion technique. The X-ray diffraction (XRD) patterns exhibited well defined single crystalline phase and formation of spinel structure. From the XRD data lattice constant was calculated. It is found that lattice constant increases with increase of Mn content, which indicates that the present compositions obey the Vegard’s law. It is also found that due to substitution of small amount of Mn average grain size, initial permeability, saturation magnetization and dielectric constant enhanced.…
