Elevated-Temperature Performance, Combustibility and Fire Propagation Index of Fly Ash-Metakaolin Blend Geopolymers with Addition of Monoaluminium Phosphate (MAP) and Aluminum Dihydrogen Triphosphate (ATP)
Khairunnisa, Zulkifly; Cheng-Yong, Heah; Yun-Ming, Liew; Bayuaji, Ridho; Mohd Mustafa Al Bakri, Abdullah; Shamsul, Ahmad; Stachowiak, Tomasz; Szmidla, Janusz; Gondro, Joanna; Jeż, Bartłomiej; Mohd Suhaimi, Khalid; Garus, Sebastian; Shee-Ween, Ong; Wan-En, Ooi; Hui-Teng, Ng (MDPI AG, 2021-04-15)Thermal performance, combustibility, and fire propagation of fly ash-metakaolin (FA-MK) blended geopolymer with the addition of aluminum triphosphate, ATP (Al(H2PO4)3), and monoaluminium phosphate, MAP (AlPO4) were evaluated ... -
Optimizing of the cementitious composite matrix by addition of steel wool fibers (chopped) based on physical and mechanical analysis
Akrm A Rmdan, Amer; Mohd Mustafa Al Bakri, Abdullah; Liew, Yun-Ming; Ikmal Hakem, Aziz; Wysłocki, Jerzy J.; Muhammad Faheem, Mohd Tahir; Sochacki, Wojciech; Garus, Sebastian; Gondro, Joanna; Hetham A, . R. Amer (MDPI AG, 2021-02)The demand for durable, resistant, and high-strength structural material has led to the use of fibers as reinforcing elements. This paper presents an investigation into the inclusion of chopped steel wool fibers (CSWFs) ... -
Self-Fluxing Mechanism in Geopolymerization for Low-Sintering Temperature of Ceramic
Faizul, Che Pa; Hasmaliza, Mohamad; Wan Mohd Arif, W. Ibrahim; Amonpattaratkit, Penphitcha; Gondro, Joanna; Sochacki, Wojciech; Norfadhilah, Ibrahim (MDPI AG, 2021-03-10)Kaolin, theoretically known as having low reactivity during geopolymerization, was used as a source of aluminosilicate materials in this study. Due to this concern, it is challenging to directly produce kaolin geopolymers ... -
Tool wear and surface evaluation in drilling fly ash geopolymer using HSS, HSS-Co, and HSS-TiN cutting tools
Mohd Fathullah, Ghazali; Mohd Mustafa Al Bakri, Abdullah; Shayfull Zamree, Abd Rahim; Gondro, Joanna; Pietrusiewicz, Paweł; Garus, Sebastian; Stachowiak, Tomasz; Victor Sandu, Andrei; Muhammad Faheem, Mohd Tahir; Erdi Korkmaz, Mehmet; Mohamed Syazwan, Osman (MDPI AG, 2021-03-26)This paper reports on the potential use of geopolymer in the drilling process, with respect to tool wear and surface roughness. The objectives of this research are to analyze the tool life of three different economy-grade ...
