Assessment of adhesion between RPC overlay and existing concrete substrate
(Trans Tech Publications, 2015)Article Preview Article Preview The number of existing structures under repair and rehabilitation has extensively increased over the past two decades; these structures typically require performance enhancements including ... -
Characterization of the interfacial bond between old concrete substrate and ultra high performance fiber concrete repair composite
(Springer Netherlands, 2013)The interfacial bond characteristics between normal concrete substrate as old concrete and ultra high performance fiber concrete as repair material have been investigated. Normal concrete substrates were first subjected ... -
Compressive Stress-Strain Behavior of Composite Ordinary and Reactive Powder Concrete
(2012)Accepted in Revised Form: March 30, 2013) Abstract: The deterioration of reinforced concrete structures is a major social problem. To minimize this problem and ensure effective structural management, the number and extent ... -
Effect of different curing conditions on the mechanical properties of UHPFC
(2012)(Received: Match 20, 2013; Accepted in Revised Form: June 22, 2013) Abstract: Ultra-High Performance Fiber Concrete (UHPFC) is a new class of concrete. Because of its distinguished mechanical properties, UHPFC is considered ... -
Evaluation of bond strength between normal concrete substrate and ultra high performance fiber concrete as a repair material
(Elsevier, 2013)In recent years premature deterioration of concrete structures due to salt damage has become a serious social problem. Repair and strengthening in order to improve the durability of these structures has become critical. ... -
Existing concrete textures: their effect on adhesion with fibre concrete overlay
(Thomas Telford Ltd, 2014)This paper quantifies the roughness parameters of existing normal concrete substrate surfaces and evaluates their effect on adhesion strength with ultra-high-performance fibre concrete overlay. Three types of substrate ... -
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 ... -
Mechanical and permeability properties of the interface between normal concrete substrate and ultra high performance fiber concrete overlay
(Elsevier, 2012)As a rule of thumb, the interfacial bonding between deteriorated concrete structures with a newly overlay repair material is one of the most important factors for structural functionality and safety as well as durability ... -
Mechanical properties of old concrete—UHPFC interface
(CRC Press, 2012)The uniqueness of Ultra-High Performance Fiber Concrete (UHPFC) is its extremely low porosity gives its low permeability and high durability, making it potentially suitable for rehabilitation and retrofitting reinforced ... -
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 ... -
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 relationship between substrate roughness parameters and bond strength of ultra high-performance fiber concrete
(Routledge, 2013)The bonding that exists between the old concrete and the new concrete depends largely on the quality of substrate surface preparation. The accurate representation of substrate surface roughness can help determine very ... -
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 ... -
Utilization of ultra-high performance fibre concrete (UHPFC) for rehabilitation–a review
(Elsevier, 2013)Under normal circumstances, reinforced concrete structures (RCS) show excellent performance in terms of durability and structural behaviour except for the zones that are subjected to severe mechanical or cyclic loading and ...
