Strength of concrete with ceramic waste and quarry dust as aggregates
(Trans Tech Publications, 2013)This research focuses on a study of the strength of concrete with ceramic waste as coarse aggregate and quarry dust as fine aggregate. The sources of ceramic waste and quarry dust are obtained from the industrial in Malaysia. ... -
Study of concrete using modified polystyrene coarse aggregate
(Trans Tech Publications, 2013)Polymer recycling has received a great deal of attention in recent years. At the present time, small percentages of polymer wastes in Malaysia are being recycled. The recycling process has typically consisted of reprocessing ... -
A study on Hydrogen Sulphide as potential tracer in landfill gas monitoring
(Trans Tech Publications, 2013)Municipal solid waste (MSW) landfills are one of the major source of hydrogen sulphide (H2S) which is the offensive odours potentially creating annoyance in adjacent communities. This project focuses on H2S emission from ... -
Study on radioactivity components, water quality and microstructure characteristic of volcano ash as geopolymer artificial aggregate
(SYSCOM 18, 2013-06)The assessments of radioactivity, water qualitytesting and microstructure characteristic of volcano ash have been examined. The measurement of the 226Ra, 232Th, 40K, and 238U were carried out using radioactive concentration ... -
Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers
(Elsevier Ltd., 2012-10)Kaolin and alkali activator were mixed with the solids-to-liquid ratios in range of 0.60-1.20 (Al 2O 3/Na 2O molar ratio of 0.63-1.27). Sodium silicate and sodium hydroxide ranged between 0.16 and 0.36 (SiO 2/Na 2O molar ... -
A study on the synthesis of fly ash-based lightweight aggregate geopolymer concrete
(American Scientific Publishers All rights reserved., 2013-01)The experiments conducting for current investigation aimed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) and explore the significance and limitations of the activator content on the ... -
Tensile and morphological properties of low density polyethylene/ spear grass composites
(Trans Tech Publications, 2014)The spear grass content on the tensile properties, morphology of low-density polyethylene (LDPE)/spear grass was investigated. The compatibilising effect of epoxidised natural rubber (ENR 50) LDPE and spear grass was mixed ... -
Tensile properties and FTIR analysis of HDPE/soya spent powder in oven aging
(AENSI Publisher All rights reserved, 2013-10)This investigation involves pure HDPE and then HDPE with addition of soya spent powder with different weight percentagesbefore and after exposing in the oven aging. The characteristics of pure HDPE and HDPE/ soya spent ... -
Tensile properties LLDPE/soya spent powder blends: Oven aging
(Trans Tech Publications, 2013)Linear low-density polyethylene (LLDPE)/soya spent powder blends with different blends ratio were prepared by using internal mixer. Soya spent powder was varied from 5 to 40 wt. The thermal degradability was assessed by ... -
Tensile properties, swelling, and water absorption behavior of rice-husk-powder-filled polypropylene/(recycled acrylonitrile-butadiene rubber) composites
(Society of Plastics Engineers, 2011-09)The effect of rice husk powder (RHP) on the tensile properties, swelling, water absorption, and morphology of polypropylene (PP)/[recycled acrylonitrile-butadiene rubber (NBRr)]/RHP composites was studied. Composites ... -
Thermal properties of linear-low density polyethylene (LLDPE)/soya spent powder blends with the addition of epoxidised natural rubber
(Trans Tech Publications, 2013)Soya spent powder as an inexpensive and renewable source has been used as a filler for linear-low density polyethylene (LLDPE) in this study. Linear-low density polyethylene (LLDPE)/soya spent powder composites were prepared ... -
Thermogravimetric analysis and the optimisation of bio-oil yield from fixed-bed pyrolysis of rice husk using response surface methodology (RSM)
(Elsevier B.V., 2011-03)The effects of pyrolysis temperature, heating rate, particle size, holding time, and gas flow rate were investigated to optimize bio-oil yield from rice husk pyrolysis. Thermogravimetric analysis showed thermal degradation ... -
