Poison’s ratio is the ratio between lateral strains and longitudinal strains. Poisson’s ratio, mathematically can be given as: V= – (lateral strain)/(longitudnal strain) When compressive force acts on a specimen then with the increase in …

Strains In Concrete | Strains Amount | Elastic Strains
Strain is the change in length as compared to original length that is before any variation. Strains in concrete are the reduction in volume of concrete after the application of loading then change in volume …

Stress is defined as; ” force per unit area.” Stress is the combination of loads like dead loads, live loads, wind loads that will acts on the structure during construction and during service life. Mathematically …

Mainly water reducing admixtures are divided into two categories depending upon the amount of dose being use in concrete and in result the decrease in the required weight of water. Low range plasticizers or regular …

A type of chemical admixtures that are used as a replacement of water is known as water reducing admixtures. By using that kind of admixtures, amount of required water for a workable concrete will be …
Continue readingEffect Of Air Entraining Admixtures On Strength
Air entraining admixtures affect the strength of concrete up to large extent. Air entraining admixtures have almost 15-25% effect on strength as compared to normal concrete. By using air entraining admixtures strength of concrete diminishes.

A place where weather is not normal (abruptly changing), air entraining admixture is used that protects concrete from different weather actions. Concrete is very weak against frost action in this water penetrates into concrete and …

There are many uncertainties in a reinforced type structures. We assume many things that even not possible in actual.
Continue readingDisadvantages Of Reinforced Concrete
Concrete is said to be reinforced when steel is used along with concrete in combination. That reinforcement gives concrete strength against its weakness I.e. tensile strength, but there are some drawbacks also of that reinforcement.

Concrete is said to be reinforced when steel is being used along with concrete for support against tensile cracking. Concrete is very weak in tension but very strong in compression. In a beam cross-section, there …
