What is the difference between Structural Concrete and Non structural Concrete?
Structural concrete is used in the construction of buildings, bridges, dams, etc. Typically there are more codes governing the use of concrete as a construction material and the concrete used has higher strength. Non-structural concrete is typically defined as being used for the construction of non structural elements. These could be parking lots, sidewalks, handicap ramps, etc. A lower strength concrete can be used and there are less rules pertaining to its use.
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?
Is the characteristic strength of a concrete the same as the compressive strength?
Yes, the characterisrtic strength of a concrete is the same as the compressive strength
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.

What is hardened concrete?
Concrete that is in a solid state and has developed a certain strength. reaction continues with time and produced hard, strong and durable solid material.
How long strength of concrete can rise and when will start to reduce?
The strength of concrete will continue to rise logarithmically forever. The rated strength is normally the 28-day strength, because at this point it will be at about 95% of its eventual strength, but it will continue to rise.Structural concrete is normally reinforced with steel. The concrete provides the compressive strength while the steel provides the tensile strength. It is a composite material, with the steel and concrete working together, but the steel can start to deteriorate compromising the strength of the composite structure - perhaps this is what you meant? When the steel corrodes the entire structure is weakened, since it relies on the tensile strength from the steel.As for when the will corrode, that is completely dependant on how it was constructed. The concrete cover over the reinforcing steel, the structural strength of the concrete, how the concrete was finished and cured, what elements the concrete is exposed to, the orientation of the concrete, the climate where the structure is built, whether there are any protective coatings on the concrete or not, the condition of the steel at the time of construction, whether or not the steel has any protective coatings or not, and many other factors all relate to the condition of the structure. If well designed, well build, and well maintained, a reinforced concrete structure can last 50 years or more with little to no signs of deterioration; however, with poor design, construction, workmanship, and maintenance, the structural integrity can me compromised in only months.If you're thinking about a future construction, make sure that it is well designed and built, and if you're talking about an existing structure and you have concerns, get it checked by a structural engineer.

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.
How do you estimate the placing of rebars?
The placement of steel reinforcing is dependent on the requirements of the strength and load-bearing of the concrete. A structural engineer should be contacted in this regard.
What is an example of compressive strength?
Concrete's capacity to withstand compressive forces is an illustration of compressive strength. A concrete structure, like a column or a beam, experiences pressure when it is subjected to a load. Concrete's capacity to withstand this pressure without breaking or deforming is measured by its compressive strength. For instance, structural concrete must have a compressive strength of at least 25 megapascals (MPa), which indicates that it can withstand significant compression without breaking. In determining the structural integrity and durability of various building materials, compressive strength is a crucial factor.
What is tensile strength of concrete?
The tensile strength of concrete is 10% of it's compressive strength.
Is the characteristic strength of a concrete the same as the compressive strength?
Yes, the characterisrtic strength of a concrete is the same as the 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 relation between tensile strength and compression strength in concrete?
tensile strength is approximately between .08 to .15 of compression strength in concrete
