The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"

What is the ultimate strength of concrete?
fy= 4000 to 4500 psi
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
What is concrete mix design?
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
Will strength of concrete mix will decrease if hot water is used?
As long as the water is liquid, the strength of the finished product will not be diminished by the water temperature.
How does concrete and steel complement each other in buildings?
That when the steel and concrete expand in say , a heat wave, the buildings walls dont get fall apart.
What is split tensile test?
Tensile strength is one of the basic and important properties of the concrete. The concrete is not usually expected to resist the direct tension because of its low tensile strength and brittle nature. However, the determination of tensile strength of concrete is necessary to determine the load at which the concrete members may crack. The cracking is a form of tension failure.
Why is strength of concrete so important in construction?
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
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 differences between C30 Concrete and C40?
The number relates to the compressive strength of a cube of concrete when tested (i.e. 30 N/mm2 or 40N/mm2) The higher the number the greater the strength of the concrete. The choice of concrete grade is usually made at the design stage for the strucutre and effects the overall strength and resistance of the strucutre to decay. You would use a higher strength concrete in a more exposed environment. It is important to use the concrete grade specified for the proposed strucutre.
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
What is the minimum thickness concrete can be poured?
any thickness of concrete can be poured however if it contains an aggregate you would be limited to the diameter of the stone. you may also replace the water component with a latex additive that will substantially improve the 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.
Why are there cracks on concrete paths?
Concrete has great compressional strength but very weak torque resistance. That means when the ground underneath concrete paths settles or erodes the concrete will crack. In order to determine where the concrete will crack the constructors leave faults in it. So when the concrete does crack it does so in such a manner that the path is still functional and aesthetic.
