High strength concrete. High strength concrete (HSC) may be defined as concrete with a specified characteristic cube strength between 60 and 100 N/mm 2, although higher strengths have been achieved and used.Strength levels of 80 to 100 N/mm 2 and even higher are being used for both precast and in-situ work in the USA, France, Norway and …

High-strength concrete resists loads that cannot be resisted by normal-strength concrete. Not only does high strength concrete allow for more applications, it also increases the strength per unit cost, per unit weight, and per unit volume as well. These concrete mixes typically have an increased modulus of elasticity, which increases …

For high strength concrete, fly ash is used at dosage rates of about 15 % of cement content. 6.3 Ground Granulated Blast Furnace Slag (GGBFS) Slags are suitable for use in high-strength concrete at dosage rates between 15-30 %. However, for very high strengths, more than 98Mpa, it is necessary to use the slag in conjunction with silica fumes.

Tensile strength of concrete. Tensile strength is the ability of concrete to resist breaking or cracking under tension. It affects the size of cracks in concrete structures and the extent to which they occur. Cracks occur when tensile forces exceed the tensile strength of the concrete.

High-strength concrete permits reinforced or prestressed concrete girders to span greater lengths than normal strength concrete girders. Also, the greater individual girder capacities may enable a decrease in the number of girders required. Thus, an economical advantage is created for concrete producers in that concrete is promoted for use in a ...

There is no definition of high strength concrete in Eurocode 2, but the measures and formulae change when the concrete strength is greater than C50/60 so this seems a reasonable working definition. High-strength concrete columns can hold more weight and therefore be made slimmer than regular strength concrete columns, which allows for …
