    • Behavior of alkali-activated fly ash through underwater placement 

      Zarina, Yahya; Mohd Mustafa Al Bakri, Abdullah; Li, Long-yuan; Nergis, Dumitru Doru Burduhos; Muhammad Aiman Asyraf, Zainal Hakimi; Sandu, Andrei Victor; Vizureanu, Petrica; Rafiza, Abd Razak (MDPI AG, 2021-11-14)
      Underwater concrete is a cohesive self-consolidated concrete used for concreting underwater structures such as bridge piers. Conventional concrete used anti-washout admixture (AWA) to form a high-viscosity underwater ...
    • A comparative study of solder properties of Sn-0.7Cu lead-free solder fabricated via the powder metallurgy and casting methods 

      Mohd Arif Anuar, Mohd Salleh; Mohd Mustafa Al Bakri, Abdullah; Sandu, Andrei Victor; Norainiza, Saud; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; McDonald, Stuart D.; Nogita, Kazuhiro (Syscom 18 SRL, 2013-07)
      The properties of Sn-0.7Cu solder bulk prepared via the powder metallurgy (PM) method were investigated and compared with solder bulk fabricated through casting. Distinct microstructures were observed in both PM and casting ...
    • 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 ...
    • The effect of various waste materials' contents on the attenuation level of anti-radiation shielding concrete 

      Ali Basheer, Azeez; Kahtan Sadiq, Muhammed, Dr.; Mohd Mustafa Al-Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Sandu, Andrei Victor; Rafiza, Abdul Razak (MDPI, Basel, Switzerland, 2013)
      Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The ...
    • Microstructural analysis of geopolymer and ordinary Portland cement mortar exposed to sulfuric acid 

      Mohd Izzat, Ahmad; Mohd Mustafa Al-Bakri, Abdullah; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Moga, Ligia Mihaela; Che Mohd Ruzaidi, Ghazali, Prof. Madya; Muhammad Faheem, Mohd Tahir; Sandu, Andrei Victor (Revista De Materiale Plastice, 2013-09)
      The vulnerability of ordinary Portland cement (OPC) concrete to acidic attack is a worrying subject regarding the future durability of this binder. On the other side of binder's technology, the new technology of cement ...
    • On the structure of shape memory alloys 

      Cristian Acitei, Dragos; Victor Sandu, Andrei; Mohd Mustafa Al Bakri, Abdullah; Petrica, Vizureanu; Alida, Abdullah (Trans Tech Publications, 2013-12)
      The paper presents the obtaining of shape memory alloys, base copper and a diffractometer and microscopic study on some samples. The study was made on CuZnAl samples, obtained by classic casting and educated. The shape ...
    • Performance of Sn-3.0Ag-0.5Cu composite solder with kaolin geopolymer ceramic reinforcement on microstructure and mechanical properties under isothermal ageing 

      Nur Syahirah, Mohamad Zaimi; Mohd Arif Anuar, Mohd Salleh; Sandu, Andrei Victor; Mohd Mustafa Al Bakri, Abdullah; Norainiza, Saud; Shayfull Zamree, Abd Rahim; Vizureanu, Petrica; Rita, Mohd Said; Mohd Izrul, Izwan Ramli (MDPI AG, 2021-02)
