What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
What is the strength of steel reinforced concrete?
The reinforcment will have little or no effect on compressive strength. It will however impact tensile strength. It depends on the concrete mix design and amount of reinforcment, what the tensile strength impacts will be. The question needs to be a lot more detailed to provide a specific answer.
What would be the effect of a concrete beam if the cover provided becomes more than specified?
strength will be reduced
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 effect of hydration on strength of a concrete?
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
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 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 the effect of age of concrete upon the water-cement ratio and strength curve?
The age of concrete significantly affects its water-cement ratio and strength. As concrete matures, its strength generally increases due to the ongoing hydration of cement particles, which leads to a denser microstructure. Initially, higher water-cement ratios may lower strength but are essential for workability; as concrete cures, the effective water-cement ratio decreases, contributing to strength gain over time. Ultimately, strength curves show that concrete continues to gain strength well beyond the initial setting period, often achieving substantial increases up to several months or years, depending on conditions.
