Mechanical properties of reactive powder concretes

Materials and Structures, 1996
Reactive Powder Concretes (RPC) are a set of ultrahigh-strength concretes reinforced with steel fibers. Their compressive strength is between 200 and 800MPa, and their flexural strength can reach 140MPa.RPC200 has been studied with respect to compressive strength and two-point loading strength to define its mechanical behavior.RPC800, which has been ...

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 ...

Reactive powder concrete with the blastfurnace slag cement

Cement Wapno Beton, 2020
The paper presents the results of tests of the reactive powder concrete [RPC] obtained from the CEM III/A 42.5 N LH/HSR/NA blast furnace slag cement, containing about 60 % of granulated blast furnace slag. The optimisation of the concrete mix composition, aimed at obtaining the largest particle packing in the composite, was carried out based on Funk’s ...

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.

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
