Buildings and their construction together account for 36 percent of global energy use and 39 percent of energy-related carbon dioxide emissions annually. Globally, the embodied carbon of buildings account for about 11 percent of emissions. The design and construction of civil engineering infrastructures are impacting global warming and climate change and the world is facing a big challenge in the form of environmental degradation occasioned mainly by global warming due to ozone layer depletion, fauna loss, deforestation and pollution. A new UN Environment Programme (UNEP) report cautioned that unless global greenhouse gas emissions fall by 7.6 per cent yearly between 2020 and 2030, the world will miss the opportunity to get on track towards the 1.5o temperature goal of the Paris Agreement on the eve of a year that nations are due to stren.....

The article presents static shear tests of adhesives connecting various types of lightweight floor system (LFS) composites with a heating coil. This method is approved for use, and its advantage is the reproduction of the real working conditions of a light floor. Preliminary tests were carried out to determine the point shear strength of selected adhesives and the target ones, using a strain gauge method of deformation measurements. Three types of adhesives used in the lightweight heated floor system were researched-cement deformable, type C2S1, C2S2, and polyurethane BondT8. In addition to determining the maximum shear stress, deformation and approximate displacement of adhesives in this type of composites, the Kirchoff ’s and Young’s modulus were also calculated. The method used did not allow determining Poiss..... ReadMore

Life on Earth depends on the circuit of water, carbon and everything that rises into the sky. In the atmosphere, their mixing, concentration, various chemical-physical processes, transformations take place, and with precipitation everything returns to the earth. On the soil, substances become the building material of bodies and plants, which, as they grow and multiply, produce waste, eat up, and waste again rise into the sky. Humanity, in its development and the pursuit of the comfort of its existence, destroys the circuits. Vapors without changing the properties of vapors are clearly visible on the water - it came with precipitation and immediately went back to the atmosphere. In nature, such fumes come from the surfaces of water bodies, from stones, and other hard surfaces. But with the development of the industry, there ar..... ReadMore

The term commuter is defined as a person who travels some distance to work on a regular basis Asensio et al. [1]. A large number of commuters are attracted every day from the suburban area because of the growing economy and urban employment opportunity of Rajshahi Islam et. al, 2016. Most of these commuters have to depend on different transport modes for their daily commuting. As commuters have to travel a long distance during the peak periods, choice of transport mode is very crucial for them. Suburban traveling is multimodal in characteristics which involve combination of multiple modes [2]. Different studies showed that mode choice plays the vital role along with the main mode for a long-distance commuting [3]. It is necessary to study different aspects of their mode choice behavior to meet the expected necessities of the co..... ReadMore

The era of oil and gas pipelines is enduring an informational renovation to recover enactment, minimalize ruptures and spills, and rise safety, and is fetching to resemble as an example of data-enabled substructure. Pipelines comes to the vision of public cognizance only when leak occurs, prominent to a toxic spill, or result in an explosion that outlays lives. The industry 4.0 is integrating sensing knowledge to monitor pressure, flow rate, pumping station parameters, temperature, viscosity, and other external parameters. The oil industry is habitually alienated into three foremost components: Upstream, midstream and Downstream. The midstream sector encompasses the transportation (by pipeline, rails, tanker or truck), loading, and comprehensive marketing of refined petroleum products. Pipelines can be incorporated to transport crude oil ..... ReadMore

The experimental study on evaluation of seismic resistance of the large-scale model of a two-story fragment of brick building from ceramic bricks on cement mortar was conducted. The dynamic testing of the prototype was carried out on the two-component vibrio plat form, where seismic impacts with the intensity of 7 to 9 according to MSK-64 scale were modelled. During the tests the constant load on floors – 4,5kH/m2 was simulated using dynamic forces to the prototype were simulated. Different options for strengthening of load-bearing brick walls concrete blocks. The dimensions of the two-storey fragment are 2,3x × 1,56 × 3,0m.

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
