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 (HSC) is a type of concrete with high compressive strength compared to normal-strength concrete (NSC). Although there is no exact limit of compressive strength that could distinguish HSC from NSC, the American Concrete Institute defines High strength concrete with a compressive strength of more than 6,000 psi.

High-strength concrete and high-performance concrete are not synonymous because strength and performance of concrete are different properties of concrete. High-strength concrete is defined based on its compressive strength at a given age whereas high-performance concrete is
The concrete is manufactured using cement, sand, gravel and water as the main components materials. The active material in concrete is cement which binds other materials physically and chemically with water and solidifies. Sometimes admixtures are used in concrete to enhance its properties. 1. Cement There are various types of cements used for manufacture of

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 ...

High-strength concretes offer a technological breakthrough in the building of columns, beams and shear walls because, with concrete two or three times as strong as ordinary, the concrete cross-sectional area or the amount of steel can be reduced, thus lessening the dead weight of the building, relieving the strain on the lower columns and ...
High strength concrete(HSC) has been feasible with latest generation High Range water Reducing admixture (HRWRA) and high reactive mineral admixtures like Silica Fumes, Matakaolin etc. High strength concrete becomes high performance concrete with right concrete mix design. Applications of High Strength concrete are high rise building (typically ...
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.
Shop QUIKRETE 80-lb High Strength Concrete Mix in the Concrete Mix department at Lowes.com. Properly graded sand and gravel blended with portland cement for use as in general concrete applications. Use for sidewalks, driveways, setting posts,
Mix Design of High Strength Concrete -Procedure. The mean design strength is obtained by applying suitable control factors to the specified minimum strength. For a given type of cement and aggregates used, the reference number corresponding to the design strength at a
Concrete with a PSI rating of 6000 or more is considered high-strength concrete. It is typically found in nuclear power plants and other areas where radiation contamination is possible. High strength concrete has a lower water-cement ratio, giving it additional durability
The global High Strength Concrete market research offers valuable insight into the current state of the local and global markets. Similarly, the High Strength Concrete market study includes a variety of user-friendly presentations and diagrams, such as maps, pie charts, and graphs that depict the percentage of different service providers strategies used in the global market.

The high strength concrete has great advantage in the modern construction scenario as many statistics show that it has not only delivered in the strength aspects but also in terms of economy. Studies show that an approximate increase of 5 times in the strength of concrete will have only about 3 to 3.25 folds increase in concrete.
Ultra high performance concrete is a modern creation that is changing the way we look at construction. While normal concrete has a strength rating in the range of 3,000 to 4,000 psi (pounds per square inch), ultra high performance concrete has a strength rating many times that.
High-Strength Concrete at High Temperature An Overview 4 C/min or 300 C/h. It is noted that the concrete temperature lags the air temperature of the furnace. Figure 3 (b) shows the temperature difference between the surface and center of the cylinder, and the rates of temperature rise on the surface and at the center of the cylinder.
High-strength concrete has a compressive strength greater than 600 kg/cm sq. HSC 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 of the cement- aggregate bond.

May 18, 2020 The most prevalent form of concrete, and the one utilized in most construction projects, is called High strength Concrete, which is usually composed of concrete containing gypsum, cement, sand, slurry, and water. Regular concrete, on the other hand, which can withstand around 10 40 MPa pressure, is mostly used for residential building projects.
May 05, 2017 The type of concrete generally with compressive strength of 6000psi (40MPa) or greater is called as HSC. We need high strength concrete in our modern infrastructures in order to put the concrete into service at much earlier stage, To build up high rise building by reducing column sizes and increasing available space or in case of long span bridges
