Modelling of Creep in High Strength Concrete

Creep is the time dependent deformation of concrete induced by sustained stress. Several different prediction models are currently used throughout the world, however little is known about their ability to predict creep in high strength concretes. Several of these models were designed to be used on normal strength concretes.

Extensibility of high-strength concretes

Materials and Structures, 1992
This paper analyses the extensibility under flexural loads of concretes with 28-day compressive strength levels up to 80 MPa. The major variables studied were loading rate, aggregate type, testing age and the environmental (moisture) conditions. It is shown that extensibility increases with concrete strength but its variation is smaller than that of ...

Superplasticizer for High Strength Concrete

MRS Proceedings, 2015
ABSTRACTIn the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 90 MPa [1]. Over the past two decades, the development of high-strength concrete has enabled builders to easily meet and surpass this estimate.

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 ...

Carbonation of High Strength Concrete

Applied Mechanics and Materials, 2011
High strength concrete consisting of binary and ternary blended cementitious systems based on ordinary Portland cement, pulverised fuel ash and silica fume were investigated for carbonation. PFA up to 40% was used and to these blends 0, 5, 10, and 15% SF was incorporated as partial cement replacement.

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 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
