Ultra High Strength Concrete

PCI Journal, 1967
A COMMISSION WAS ESTABLISHED ON METHODS OF ACHIEVING HIGH- STRENGTH CONCRETE TO FIND OUT WHETHER THE EFFECTIVE COMPRESSIVE STRENGTH OF CONCRETE CAN BE SUBSTANTIALLY INCREASED SO THAT PRESTRESSED CONCRETE MAY BECOME NOT MERELY AN ECONOMIC STRUCTURAL MATERIAL OF ATTRACTIVE CHARACTERISTICS, BUT A MATERIAL OF HIGH SPECIFIC STRENGTH AS WELL.

Creep of high–strength concrete and normal–strength concrete

Magazine of Concrete Research, 1991
The development and use of high–strength concrete has been evolutionary. High–strength concrete is used for tall buildings, bridges, long–span structures and offshore platforms. Very little information is available on the creep of high–strength concrete compared with that of normal concrete at room and low temperatures.

High-Strength Concrete in Ultimate Strength Design

Journal of the Structural Division, 1978
The ultimate behavior of concrete structural members was predicted based on the knowledge of the concrete and the steel stress-strain curves and using nonlinear computerized methods. The calculated values of ultimate moment and curvature were compared with some experimental values for beams and columns.

Shear strength of high strength concrete beams

1991
This brief article investigates the shear strength of high strength concrete beams with and without stirrups. Thirty three beams, (of which 12 were without stirrups), having compressive strength in the range of 64 to 90 MPa were tested. The following variables were considered: concrete strength; shear span to effective depth ratio (a/d); and the amount

High Strength Pervious Concrete

Pervious concrete is increasingly being utilised in the construction of driveways, parking lots, and pavement in many industrialised nations. Testing must be done to assess the performance of this new kind of high-performance concrete in order to establish material specifications for pervious concrete. Additionally, the manufacturing of Portland cement

Confinement of High-Strength Concrete

SP-176: High-Strength Concrete in Seismic Regions, 1998
Recent research on confinement of high-strength concrete (HSC) is reviewed. The emphasis is placed on the effects of confinement parameters and related experimental research. A review of analytical models proposed for HSC is also presented. The results indicate that for similar strength and deformability, HSC requires higher confinement pressure than ...

High strength concrete for prestressed concrete girders

1991
This paper illustrates that the use of high strength concrete allows increasing the span of prestressed girders with given cross section. It is also indicated that for a given span length, girder spacing can be significantly increased. These benefits are demonstrated by means of numerical examples, which give formulae to calculate the maximum span ...
