Effects of thermal damage on physical properties and cracking behavior of ultrahigh-performance fiber-reinforced concrete

open access: yes, 2016
International audienceIn this work, we study the impact of thermal damage on the physical and mechanical properties of ultrahigh-performance fiber-reinforced concrete (UHPFRC), especially on their cracking process under compressive loading. Four mixtures

Shrinkage Cracking Propensity of UHPC

open access: yesSecond International Interactive Symposium on UHPC, 2019
It is widely accepted that ultra-high performance concrete (UHPC) provides better mechanical and durability properties than high performance or conventional concrete. The high cementitious materials and fiber contents are key to its change in properties, making this type of material suitable for a wide range of structural applications. However, because

Cracking Behavior of UHPC Slabs

open access: yesEngineering and Technology Journal, 2015
The combination of fibers with traditional reinforcement may be a very interesting design solution to achieve more durable and economical structures. In this study, a total of seven slabs; six ultra high performance concrete (UHPC) slabs and one normal strength concrete slab were tested previously by the Author to observe the crack spacing and number ...

Modular constructions made of UHPC [PDF]

open access: yes, 2013
CNC-machine. The dry joints of the arch construction remain under compression in SLS. The assembling of the arch lasted only two weeks by applying swivel-in method of arch construction. For the design of the arch the development of new calculation models and a lot of experimental tests including also full scale tests was required.

Physical properties of concrete containing graphene oxide nanosheets [PDF]

open access: yes, 2019
Concrete made from ordinary Portland cement is one of the most widely used construction materials due to its excellent compressive strength. However, concrete lacks ductility resulting in low tensile strength and flexural strength, and poor resistance to
