Abstract
The aim of this study was to utilize ethyl cellulose, mixture of waste engine oil and waste vegetable oil as a binder in the environmental friendly roofing tile production. The waste engine-vegetable oil wasmix together with ethyl cellulose, fly ash, coarse aggregates, fine aggregatesand a catalyst. The Fourier Transform Infrared (FTIR) analysis showed that the oil mixture added with ethyl cellulose has the relatively high binding effect due to the presence of strong carbonyl group especially after being heat cured at 1900C for 24 hours. The mixed proportion of materials with different amount of ethyl cellulose used was studied in the production of tile specimen. The results showed that the ethyl cellulose composed roofing tile specimens passed the transverse breaking strength, durability, permeabilityand the ultraviolet accelerated test. The shrinkage on the tile can be overcome by adding temperature resistance polymer on the exterior of the tile.
Highlights
IntroductionEthyl celluloseoffers an attractive range of physical properties and blended with other materials to achieve intermediate characteristics like roofing tile that used asa binder
2.1 Preparation of the materials Waste engine oil and waste vegetable oil were collected from local car station and restaurant respectively.The waste engine-vegetable oil was blended in the ratio 1:3 and different amount of ethyl cellulose powder were added to the mixture in an orbital shaker at 300 rpm at 1000C for 30 minutes to dissolve it
The ethyl cellulose polymers used werefrom ETHOCEL branded from Sigma-Aldrich.The river sand was used in the mixture to produce tiles
Summary
Ethyl celluloseoffers an attractive range of physical properties and blended with other materials to achieve intermediate characteristics like roofing tile that used asa binder. It provides a green strength to the unfired roofing tile and burnt out clearly leaving no residue after firing. Ethyl cellulose polymer has been widely used in applications like pharmaceutical, personal care, food, specialty applications and others due to their physical and chemical properties [1]. Ethyl cellulose is used as a binder in some clay products, gives good binding strength, and fires out of the ceramic with an ash residue of only 0.5%. A phase separation method is used to mix the rosemary oil with ethyl cellulose microcapsules. The stirring speed of the encapsulation affected the size and degree of sphericity of the microcapsules [4].The polymer ethyl
