Abstract

High-Strength High-Fluidity Concrete becomes more and more widely used
in construction of high-rise buildings in the World. In Vietnam this type of
concrete has just been used in some projects like Hanoi Keangnam
Landmark Tower, by a South Korean firm. There are someresearch works
related to theHigh-Strength High-Fluidity Concrete by Vietnamese
researchers which have been publishedwith the results achieved in
laboratory trail phase alone. This paper reports on the test of the High-
Strength High-Fluidity Concrete both in the laboratory and site conditions.
The targets set for High-Strength High-Fluidity Concretewithslump flow
above 600 mm, the 28-day compressive strength >65 MPa and the 56-day
compressive strength >75 MPa without segregation and bleeding have been
achieved.
