Carbonation of High Strength Concrete
Applied Mechanics and Materials, 2011High 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.

Properties of High-Strength Concrete
Cement, Concrete, and Aggregates, 1986Abstract This paper presents data related to the development of high-strength concrete with special emphasis on the development of high early strength. Both these objectives were achieved by using an ultrafine portland cement with a specific surface of about 750 m2/kg or a high early strength portland cement with about 75% tricalcium ...

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.openaire +4 more sources
High strength concrete for prestressed concrete girders
1991This 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 ...

Extensibility of high-strength concretes
Materials and Structures, 1992This 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 ...

Confinement of High-Strength Concrete
SP-176: High-Strength Concrete in Seismic Regions, 1998Recent 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 cementopenaire +1 more source
