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 HighStrength 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.
