As it is developed through a coating process, it does not only help to increase fertilizer's efficiency, but also minimize the loss of nutrients into the soil and environmental pollution. There are many types of coating materials that have been extensively studied as well as applied in everyday life from pharmaceutical industry to engineering industry such as in pharmaceutical tablet, road construction and corrosion control of steel structures like offshore platforms. In this research, the alkali-activated material composite has been developed as a new coating material and is introduced as the main coating material for the CRU. In term of environmental friendliness, alkali-activated material (AAM) is considered better than sulphur and polymer. However, the combination of fly ash and sodium hydroxide (NaOH) solution producing the AAM paste needs further research since it can be categorized as a novel coating material for CRU. It is also to ensure the suitability of it to be used as a coating material on urea fertilizer. A significant coating thickness along with good hardness strength can produce promising coated urea granules characteristics. Two parameters have been studied for this research to identify its effect towards coating thickness and hardness strength of coated urea granules which are inlet air pressure and spraying rate. These two parameters are identified to be crucial in enhancing the characteristics of coated urea granules. © 2018 Authors. date: 2018 publisher: Science Publishing Corporation Inc official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85082373846&doi=10.14419%2fijet.v7i3.26.17457&partnerID=40&md5=879083240c981410e9e6c741ee6f1dfc id_number: 10.14419/ijet.v7i3.26.17457 full_text_status: none publication: International Journal of Engineering and Technology(UAE) volume: 7 number: 3 pagerange: 33-37 refereed: TRUE issn: 2227524X citation: Luqman Hakim, H. and Ku Zilati, K.Z. and Muhammad Harris, N.
