Efficiency of treated and untreated palm oil fuel ash as a supplementary binder on engineering and fluid transport properties of high-strength concrete
(Elsevier, 2016)The primary focus of this work was to utilize the waste of palm oil industry as a supplementary binder for producing high strength concrete (HSC) whose strength reached 116 MPa. The treatment of ground POFA (GPOFA) to ... -
Flexural Strength Behavior of Composite UHPFC-Existing Concrete
(Trans Tech Publications, 2013)Article Preview Article Preview Ultra high performance fiber concrete (UHPFC) is an advanced formula concrete that is proven to be more superior than conventional concrete because it embrace the qualities of steel and ... -
Improving the engineering and fluid transport properties of ultra-high strength concrete utilizing ultrafine palm oil fuel ash
(Japan Concrete Institute, 2014)Ground treated ultrafine-POFA obtained from palm oil industry was heat-treated to remove excess carbon. The varied proportion (17%, 30% and 40%) of UPOFA was incorporated into the ultra-high strength concrete (UHSC) to ... -
Microstructural analysis of the adhesion mechanism between old concrete substrate and UHPFC
(Taylor & Francis, 2014)The performance of any repaired concrete structure, and thus its service life, depends on the quality of the interfacial transition zone of the composite system formed by the repair material and the existing concrete ... -
Pozzolanic reactivity of ultrafine palm oil fuel ash waste on strength and durability performances of high strength concrete
(Elsevier, 2017)Palm oil fuel ash (POFA) was utilized as a pozzolanic material in varied quantities to produce high-strength concretes (HSCx) of above 90 MPa, with significant improvement in its engineering and fluid transport properties. ... -
PROPERTIES OF ULTRA-HIGH PERFORMANCE FIBER CONCRETE (UHPFC) UNDER DIFFERENT CURING REGIMES
(IAEME Publication, 2017)Ultra-High Performance Fiber Concrete (UHPFC) is one of the breakthroughs in the 21st century in the field of concrete technology where this composite material providing an important improvement in strength, workability, ... -
The role of silica fume in the adhesion of concrete restoration systems
(Trans Tech Publications, 2013)Article Preview Article Preview Article Preview The weak interfacial transition zone between new and old concrete is always paid much attention and controls many properties of repaired concrete, The present work reports a ... -
Workability, Setting Time and Strength of High-Strength Concrete Containing High Volume of Palm Oil Fuel Ash
(2018)Methods: The workability (slump, slump loss, and compacting factor), initial and final setting times and strength in both forms of concrete were investigated. Results and Conclusion: The results showed that HSCu had improved ...
