Comparative Study of Clinker’s Transformation at Different Temperature Zone During Cement Production
(Science Publications, 2007)
Chemical composition analysis using x-ray fluorescence is one of the important quality
analysis for examining of cement and widely used in cement industries for a long time as a tool to estimate phase composition. X-ray ...
A study of comminution-liberation and floatability of Copper from printed circuit boards (PCBs) scrap
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
Printed circuit boards (PCBs) were collected from obsolete or defective computers that are the largest source of the kind of waste. PCBs are composed of different materials such as polymers, ceramics and metals. The studies ...
Comparative characterization of Clinker’s microstructure at different temperature zone during cement production
(Science Publications, 2007)
Temperature is an important parameter for transformation of minerals in clinker during
cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of ...
Concrete Ceramic Waste Slab (CCWS)
(Kolej Universiti Kejuruteraan Utara Malaysia, 2006)
The main focus of this research is to study the strength of concrete with ceramic waste as coarse aggregate. The source of ceramic waste are obtained from industrial in Malaysia. Presently, in ceramics industries the ...
The effect of compatibilizer on tensile properties, swelling behaviour and morphology of Calcium Carbonate filled Polypropylene/Ethylene Propylene Diene Terpolymer composites
(Universiti Kuala Lumpur (UniKL), 2007-11-27)
Calcium carbonate (CaCO3) was used as filler in the polypropylene (PP)/ ethylene propylene diene terpolymer (EPDM) composites in order to decrease cost and change the properties. The composites were prepared by using a ...
Recycling waste tire into concrete-rubber composite
(Universiti Kebangsaan Malaysia (UKM), 2009-10-20)
This research is to recycle waste tire to a concrete-rubber. The objective of this research is to investigate the possibility of using rubber particles as a replacement for the natural aggregates in concrete. These ...
Selective leaching for the recovery of Copper from PCB
(Universiti Malaysia Perlis, 2009-12-01)
This paper reported on the leaching behavior of printed circuit board (PCB) using a new leaching agent of ammonia-ammonium persulfate, to recover copper. Cu and Zn leaching were found to be fast and reached equilibrium in ...
Agregat Ringan Sebagai Bahan Binaan
(Universiti Malaysia Perlis (UniMAP), 2008)
Pengenalan : Penggunaan agregat ringan sebagai bahan binaan di negara ini masih belum digunakan secara meluas. Walau bagaimana pun pengingkatan penggunaan konkrit ringan di dalam industri pembinaan memangkin kepada penggunaan ...
The fabrication of artificial marble from dolomite (Batu Reput)
(The Mineral, Metals & Materials Society (TMS), 2006-01)
Perlis is one of the major producers of "Batu Reput" in Malaysia and majority of the deposits contain of high-purity calcium and magnesium carbonate. The composition of Batu Reput is similar with the ordinary dolomite. ...
Extraction and separation of Cu(II), Ni(II) and Zn(II) by sol-gel silica immobilized with Cyanex 272
(Elsevier B.V., 2009-03)
The extraction and separation of Cu(II), Ni(II) and Zn(II) from aqueous sulfate-acetate solution were carried out using solid phase sol-gel silica containing immobilized Cyanex 272 {bis(2,4,4-trimethylpentyl)phosphinic ...
