PublicationApplication of coal bottom ash as raw material for concrete brick in housing construction( 2020-03-25)
;Omar S. Dahham ;Umar M.U.Jaya H.Coal and coal-fired power plants are crucial for supplying global energy demand. However, coal-fired power plants produce significant quantities of bottom ash as by-products. Through these power plants, it produces approximately 18 tons of bottom ash each day. Malaysia has the challenging task of dealing with an increasing amount of waste generated by power plants each year. The high cost of construction and operation of incineration plants coupled with a lack of landfills have given rise to the need for waste minimization and recycling. The use of coal ash in concrete is a new dimension in concrete mix design and if applied on large scale can revolutionize the construction industry, by economizing the construction cost and decreasing the ash content. The used of the coal bottom ash in the concrete brick can reduce the wastage of the coal bottom ash in Malaysia, beside that the cost of the housing can be reduced. In addition, the sustainability in the housing construction in Malaysia can be achieved using the wastage material in the construction. -
PublicationThe sustainability of recycled concrete as green material solution( 2020-03-25)
;Dahham O.S. ;Umar M.U.Johari I.Nowadays, there are lot of concrete waste were produced from demolition, destruction and others. The usage of concrete is not environmentally friendly due to depletion of reserve natural resources, high energy consumption and disposal issues. Construction debris give a large fraction of solid waste disposal problem, and constitutes the large component. By recycling concrete waste for brick production as replacement the other materials, it can reduce the usage of natural resources and disposal problem that have been occur. The aim of this study to determine the sustainability of the recycled concrete by producing a brick using recycled coarse concrete aggregate at nominal size 10mm. An experiment done by comparing the result of the control specimen using 100% natural sand with specimen that have replaced the sand with recycled concrete aggregate for 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. The result showed the optimum recycled concrete to produce a brick is at 90% replacement of RCCA where the compressive strength and flexural was achieved 9.7MPA and 3.53MPA respectively with 16133.33 kg/m3 of density. The water absorption of green brick is 9.23% and the cost of brick have been reduced from Rm0.26 to 0.20.1 -
PublicationThe effectiveness of highway information modeling in Kuala Perlis - Changlun Roadway( 2020-03-25)
;Dahham O.S. ;Umar M.U.Jaya H.Road and highway observation is critical for road engineers to determine the information of the highway itself for the needs of maintenance, rehabilitation and even in construction. This research reviews the efficiency of information of roads and highway by visual and experience. The mean of visual includes the usage of Unmanned Aerial Vehicles (UAV) and on spot observation. It also reveals the image based, photogrammetric and stereo-vision, and mobile mapping systems.The software output has compatibility with known CAD/GIS packages to widen its scope of applications. Methodologies, examples and demonstration related to the use of the developed software and laser scanning data in road mapping for a case study are described. The results showed the flexibilities of the developed software and the proposed method for generating the necessary maps and data for road distresses such as longitudinal cracks, transverse cracks, patch deterioration, potholes, and ravelling. However, the present work shows that using terrestrial laser scanning technologies for modelling the road surface has advantages such as surveying speed, big roads, highways and tunnels. Also it provides the safety for surveyors and the absence of a disruption to traffic. The developed software and methodology are suitable for universities, academic centres and are of great interest to small engineering firms for the generation of road surface maps.1 -

;Tian T.Y. ;Yahya S.S. ;Shahrazel A.A.M. ;Mansor F.M. ;Aziz S.Z.A.Hussain A.S.T.This study investigates the ability of Unmanned Aerial Vehicle (UAV) spraying systems to be used as an agriculture spraying method in Malaysia. The operating height of the UAV was 1.5 m with three different nozzles were investigated within a wind speed of 1.15 m/s to determine spray uniformity and dispersion in the paddy field conditions. The results from these samples were evaluated by using ImageJ software. The results show that the droplet distribution by using an electrostatic centrifugal nozzle has a high average droplet density, which is 134.03 deposits/cm2 for the top area and 153.93 deposits/cm2 for the bottom area. The electrostatic centrifugal nozzle also testified to the high value of total droplet deposit at 3478 for the top area and 3255 for the bottom area.1 -
PublicationFTIR and gel content analyses of LLDPE/Date seeds composites( 2020-03-25)
;Elnaid A. ;Dahham O.S.Umar M.U.The potential of Date Seeds (DS) as a filler was studied. DS were collected, washed and grinned. Three different DS were used, i.e. coarse size (between 700-1000 μm), medium size (between 250-500 μm) and fine size (between 0-125 μm). After that, DS was mixed with linear low-density polyethylene (LLDPE) ar different DS content i.e. 5, 10, 15, and 20 %, and then fed into a twin-screw extruder and subsequently into an injection-moulding machine to produce LLDPE/DS biocomposite. FTIR and Gel-Content analyses were applied in order to study the properties of this composite. It is found that the composites showed five main peaks, at 3345-3347 cm-1, 2910 cm-1, 2847-2848 cm-1, 1462 cm-1, and 718-719 cm-1 respectively. These peaks indicated the existence of LLDPE polymer matrix, DS filler and the interaction between them in the composites. However, there was no significant change in the gel content of the composites compared to LLDPE control, which means the number of crosslinks between LLDPE and DS was limited. The lack of a suitable coupling agent system has effected negatively on the degree of crosslinking of the composite.1 -
