Why it is need to use high strength concrete in prestressed concrete?
to offer high resistance in tansion,shear and bond
Why in case of high strength concrete you are getting step snoop of curve after cracking of concrete?
gravitation is inversly proportional to weaight
What is tensile strength of concrete?
The tensile strength of concrete is 10% of it's compressive strength.
How does the moisture affect the strength values of concrete?
the moisture of concrete is main strength for reinforced concrete structure
What is the strenght of concrete?
The strength of concrete is primarily measured by its compressive strength, which indicates how much load the material can withstand without failing. This strength is typically expressed in megapascals (MPa) or pounds per square inch (psi) and varies depending on the concrete mix design, curing conditions, and the materials used. Standard concrete typically has a compressive strength of about 20 to 40 MPa (2,900 to 5,800 psi), while high-strength concrete can exceed 70 MPa (10,000 psi). Other factors, such as the water-cement ratio and the use of additives, also influence concrete's overall strength and durability.
What is high strength concrete?
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.
Why are bridges made of steel and concrete?
Steel is used for its high tensile strength and the concrete is used for its high compression strength.
Is microsilica used in high-strength concrete?
Yes, Silpozz microsilica is commonly used in high-strength concrete to enhance strength and durability, especially for structures that require exceptional performance.
Why it is need to use high strength concrete in prestressed concrete?
to offer high resistance in tansion,shear and bond

What two basic grades of concrete for paths and driveways?
The two basic grades of concrete commonly used for paths and driveways are standard concrete (often referred to as "normal strength concrete") and high-strength concrete. Standard concrete typically has a compressive strength of around 20-25 MPa (megapascals) and is suitable for light to moderate traffic. High-strength concrete, with a compressive strength of 30 MPa or higher, is recommended for areas that experience heavier loads or more intense wear and tear. Selecting the appropriate grade depends on the anticipated load and usage of the surface.

What is strength of the concrete used in Burj Khalifa?
The Burj Khalifa utilizes high-strength concrete with a compressive strength of around 80 MPa (megapascals) to support its immense height and load. In some areas, the concrete strength reaches up to 100 MPa. This high-performance concrete not only provides structural integrity but also allows for the building's innovative design and resilience against environmental factors.
Why in case of high strength concrete you are getting step snoop of curve after cracking of concrete?
gravitation is inversly proportional to weaight
How does concrete behave in fire?
Concrete will react differently according to the temperature experienced. for normal strength concrete nothing will happen at less than 500c but after that it starts losing its strength and cracks will appear will fail from 5-6 hours and it may explode but exploding is less likely to happen but for high strength concrete at a very high 500c-700c it well explode suddenly
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
What is concrete 240 ksc?
"240 ksc" is a unit of pressure measurement typically used to rate the strength of concrete. It means that the concrete can withstand a pressure of 240 kilogram-force per square centimeter, indicating high compressive strength. Such concrete is usually used in structural applications like bridges and high-rise buildings.
