Study of concrete using modified polystyrene coarse aggregate

Mohd Mustafa Al-Bakri, Abdullah; Zarina, Yahya; Norazian, Mohamed Noor; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Rafiza, Abdul Razak (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 ...

Design, processing and characterization of fly ash-based geopolymers for lightweight concrete application

Mohd Mustafa Al-Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Sandu, Andrei Victor; Mohamed, Bnhussain, Prof. Dr.; Zarina, Yahya; Rafiza, Abdul Razak (Institute for Scientific Information (ISI), 2013-04)

The mix design of geopolymers plays important role in obtaining desirable compressive strength. Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the ...

Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete

Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Mohamed, Bnhussain, Prof. Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Rafiza, Abdul Razak; Zarina, Yahya (American Scientific Publishers, 2013-12)

The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...

Effect of palm slag filler size on the mechanical and wear properties of brake pad composites

Che Mohd Ruzaidi, Ghazali, Assoc. Prof.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Mohd Mustafa Al Bakri, Abdullah; Rafiza, Abdul Razak (American Scientific Publishers, 2013-01)

Particle size of filler and other material that involved in brake pad composites are expected to be able to strongly influence the wear properties and performance. Palm slag as a filler in brake pad was investigated in ...

Microstructure studies on the effect of the alkaline activators of fly ash-based geopolymer at elevated heat treatment temperature

Mohd Mustafa Al-Bakri, Abdullah; Omar A., Abdulkareem; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Rafiza, Abdul Razak; Zarina, Yahya; Alida, Abdullah (Trans Tech Publications, 2013)

Fly ash-based geopolymers are new binding materials produced to replace the ordinary Portland cement (OPC) used in concrete. In this research, the effect of alkaline activators on the compressive strength and the microstructure ...

Review on the various ash from palm oil waste as geopolymer material

Zarina, Yahya; Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Rafiza, Abdul Razak (Advanced Study Center Co. Ltd., 2013)

The solid waste from palm oil mill industry has been increasing annually where it has been reported that the palm oil waste was produced 4 million tons/years in Malaysia only. Hence, the solution to overcome the problems ...
