Durability of Green Reactive Powder Concrete

2013
In marine environment, due to the effect of chloride ion, sulfate, magnesium ions, dry-wet cycle, and freeze-thaw cycle, the damage of reinforced concrete bridge pier is extremely serious. Reactive powder concrete, which is considered as a kind of green high performance concrete, has high durability, high strength and presents good environmental ...

Hole Damage in Drilling of Reactive Powder Concrete

Journal of Materials in Civil Engineering, 2011
This study deals with the analysis of hole damage in the drilling of reactive powder concrete (RPC). Attention was first focused on the definition of an original approach on the basis of digital image processing (DIP) to quantify the extent of the damage.

Durability Analysis Testing on Reactive Powder Concrete

Advanced Materials Research, 2013
Reactive powder concrete (RPC) has been proposed as barrier materials for the construction of engineered barrier in Taiwan. The durability characteristics of RPC in such applications become paramount for the success of the containment of the wastes. The adverse environmental conditions at the disposal site could attack concrete barrier and results in ...

Nondestructive Evaluation of Reactive Powder Concrete

AIP Conference Proceedings, 2004
Reactive powder concrete (RPC) has been introduced as a structural material for civil engineering applications. The material consists of a finely graded combination of cement, sand, ground quartz and silica fume which combined with water form a cement paste.

Microstructural analysis of RPC (Reactive Powder Concrete)

Cement and Concrete Research, 1995
Reactive Powder Concretes (RPC) are characterized by high silica fume content and very low water to cement ratio. Granulometry and heat treatment were optimized to obtain excellent mechanical and durability properties. The study of several RPC compositions by Mercury Porosimetry, Thermogravimetric Analysis and X-ray diffraction made it possible to ...

Silica Fume Distribution and Reactivity in Reactive Powder Concretes

"SP-178: Sixth CANMET/ACI/JCI Conference: FLy Ash, Silica Fume, Slag & Natural Pozzolans in Concrete", 1998
Transmission Electron Microscopy (TEM), Scanning Transmission Electron Microscopy (STEM) and Chemical Analysis investigations lead to a fine characterization of Reactive Powder Concretes elaborated under different conditions as pressure application during setting and post-set heat treatment. An abrasive thinning method followed by ionic etching allowed

Flexural Strength of the Reactive Powder Concrete

Solid State Phenomena, 2016
Reactive powder concrete (RPC) is cement composite which is characterized by an absence of coarse aggregate. That resulted in a greater homogeneity of the mixture and thus also in a higher compressive strength. On the other side, the absence of coarse aggregate and typically a large volume of the paste lead to the deterioration of some of the ...
