High-Strength Concrete Portland Cement Association

High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.

High Strength Concrete — What, why,how? Nevada Ready Mix

It is a type of high performance concrete generally with a specified compressive strength of 6,000 psi (40 MPa) or greater. The compressive strength is measured on 6 × 12 inch (150 × 300 mm) or 4 × 8 inch (100 × 200 mm) test cylinders generally at 56 or 90-days or some other specified age depending upon the application.

High strength concrete

High strength concrete. The definition of high strength concretes is continually developing. In the 1950s a cube strength of 35MPa was considered high strength, and in the 1960s compressive strengths of up to 50MPa were being used commercially. More recently, compressive strengths approaching 140MPa have been used in cast-in-place buildings.

The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of

High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). In the UK, BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement matrix, which might reduce the strength at the cement-aggregate bond.

Normal Concrete vs. High-Strength Concrete Properties and

The high strength concrete has a lower value of permeability compared to normal strength concrete. This is because the high strength concrete is designed with lower water cement ratio. They commonly use silica fume in their mix. The high strength concrete has a permeability coefficient that ranges from 1 x 10-11 to 1 x 10-13 cm/sec.

Designing a High Strength Concrete Mix| Concrete

The age at which concrete must develop its high strength is an important factor in the design of a mix. If high early strength is required, it can often be achieved by modifying an existing mix design to incorporate: (1) Type III rather than Type I or Type II portland cement; (2) additional cement; (3) an accelerator, such as calcium chloride; and/or (4) a water-reducing admixture.
