This method of Lightweight floor construction does not require the use of heavy concrete screeds. It consists of a layer of hard thermal insulation on which the tile flooring is directly mounted, usingan adhesive mortar reinforced with a glass fiber mesh. This article summarizes the current results of the strength tests of this radiator model with XPS thermal insulation for bending, compression and point compression with a variety of constructional models. Application in all tests of various types and structures of insulating panels, with the use of glass fiber mesh and without it, allowed us to check and compare the most important strength parameters with different variants. At the same time, the principle of accepting materials that produce results guaranteeing the quality, durability and optimal pr..... ReadMore

Manufacturing of fly-ash bricks are the very useful alternatives of conventional burnt clay bricks. Manufacturing of clay bricks cause top soil removal, environmental pollution and health problems. To avoid all this environmental threats an attempt is made to manufacture of bricks using fly-ash, gypsum, sand and cement. Mainly fly-ash bricks are made by applying compressive load on the mold. In this research, the effect of brick forming load on the crushing load, water absorption and unit volume weight were studied. For this purpose bricks were prepared for different fly-ash (50% to 65% at 5% increments), gypsum (12% to 3% at 3% decrements), sand (28% to 22% at 2% decrements) and 10% cement. All ingredients were thoroughly mixed and then poured them to a mold of 9.5cmx4.5cm x 2.75cm. Bricks were made by different forming load and mechanic..... ReadMore

This study is about the effect of fly ash as filler on bituminous mix design under various condition. The main purposes of this project is to study the possibility of using fly ash as mineral filler in bituminous paving mixes where in general stone dust are used. Fly ash from Barapukuria Coal Power Plant has been used in the present experimental work. Suitable aggregate grading is selected for bituminous mixes. Standard Marshall Mix design procedure is followed in the design by using standard filler stone dust and testing of those mixes to determine the density, stability, flow, voids in mixes and optimum bitumen content. By this optimum bitumen content, mixes are prepared by replacing standard filler stone dust with fly ash at levels 25%, 50%, 75% and 100% by weight of total filler. The mixes are tested to obtain optimum fly ..... ReadMore

Agricultural is the largest employment sector of Bangladesh and most of the people earn their living from agricultural production. The magnitude of agricultural production varies spatially as agricultural production depends on topography, the fertility of the land, availability of river, availability of marketing place, input and so on. The intent of our study is to regionalize all the 64 districts of Bangladesh based on Boro production, fish production and the number of growth center and to analyze the impact of it on rural development. To do so, the data are collected from the Bangladesh Bureau of Statistics (BBS), the composite index method was employed to analyze the data. The data reliability is checked through statistical parameters named level of skewness, kurtosis and standard error of the mean. The..... ReadMore

The aim of this study is the use of local materials (plaster, sand dunes and date palm fiber) for the region of southern Algeria. By expand areas of the use of these materials in the field of construction. Despite the large ament of gypsum, its use is limited to some secondary operations like coatings and decorative elements. The sand dunes and palm fiber, its use in the construction are very limited. In this study, the sand dunes and palm fiber was added to plaster, to find the mortar that has physical and mechanical properties that allow its use in construction. The results obtained showed that the addition of date palm fibers improves the physical properties (density, water absorption, etc.) and mechanical properties (compression strength, flexural strength, etc.)......

This paper outlines the utilization of municipal plastic waste (MPW) in construction industries. Both the MPW and the construction industries are increasing rapidly and world’s recycling rate of either Municipal Solid Waste (MSW) or MPW specifically is still low. Production of bricks is non-eco-friendly and a waste generating process because of the greenhouse gases released. Utilizing MPW as construction materials especially in production of bricks is one of a promising step towards a sustainable resources and waste management. Plastic waste can substitute either partially or completely one or more of the materials in brick production. Further research based on recent research and a better understanding in utilization of plastic waste in brick is needed to produce a high durability and quality of bricks as well as to achieve the optimum.....

TMT bars means Thermo Mechanically Treated Bars made from medium carbon steel (Carbon 0.25 Max Wt. %) and are used in construction industry. Because of its corrosion and rust resistance features it is widely used in construction of buildings in humid areas as well as long lasting, high strength, quality construction. Quality aspects of these rebar’s are of significance as any inherent abnormality in the material could lead to unwanted productivity losses or quality claims. In this present study, rebar samples failed during bending operation were collected from construction end for understanding their quality aspect and potential causes of failure while bending. Visual observations of rebar sample (U-bend) longitudinal surface defects were observed in both the tension and compression zone. On appearance, metal folded over the..... ReadMore

This paper reports on a study carried out to optimize the locations of multiple discharge points in a receiving stream, Amadi creek, so as to minimize the impact of oxygen demanding resources (BOD) on water quality. The study evaluated the water quality changes as a result of the increasing human and industrial activities around the creek. Water quality standards require the maintenance of dissolved oxygen (DO) concentration of 5mg/l or more at any time in streams. However practical analysis of the water samples from Amadi creek reveal a DO level as low as 2.3mg/l. The DO deficit was computed from data generated by sampling DO concentrations along the creek from various points of waste discharge downstream while the BOD of the stream was determined by monitoring BOD of samples obtained along the creek. The study also identified and quanti..... ReadMore

The use of Steel Fiber Reinforced Concrete (SFRC) has received a tremendous impulse in the last years in an attempt to push forward the boundaries of high-end structural applications. Generally, concrete is characterized by brittle failure, which limits the application and can be overcome by the inclusion of a small amount of short randomly distributed fibers (steel, glass, synthetic and natural) and can be practiced among others that remedy weaknesses of concrete, such as low ductility, high shrinkage cracking, low durability, etc. SFRC has the ability of excellent tensile strength, flexural strength, impact resistance, fatigue resistance, ductility and crack bridging. Therefore, it has been applied abroad in various professional fields of construction. Steel fiber reinforced concrete (SFRC) is a heterogeneous structural material compr..... ReadMore

The increment of vehicles due to the proportional increment of populations and a rapid development of modern society is a major concern in Metropolitan cities in developing countries like Bangladesh. So, it is imperative to monitor traffic volume as well as the quality of transport supply termed as the Level of Service (LOS). The present study is an investigation of the behavior of mixed traffic flow in Rajshahi city of Bangladesh. Field Traffic volume survey was carried out to determine the level of service at 3 major Unsignalized intersections in Rajshahi city corporation (RCC). Level of service (LOS) was determined by volume capacity ratio and peak hour factor (PHF) method. Nature of traffic flow in Rajshahi city is heterogeneous. So, this heterogeneous or mixed traffic are simplified by Passenger car unit (PCU). T..... ReadMore
