What is Fire Resistance of Concrete? Mechanism and Factors

Fire resistance of concrete is the ability of concrete to withstand fire or to give protection against fire. This involves the ability of concrete structural element to continue perform a specific structural function or confine fire or both.

What is Poisson’s Ratio of concrete?

Poisson's ratio of concrete is the ratio of transverse strain to longitudinal strain in concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of ...

What is Reinforced Concrete? Uses, Benefits, and advantages

Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). This combination is made to use the compressive strength of concrete and tensile strength of steel at the same time, hence, work together to resist many types of loading. ...

Concrete Sweating – Phenomenon, Causes and Prevention

Concrete sweating is the phenomena of accumulation of water droplets on the surface of concrete due to the difference in temperature of the outer environment and concrete. A sweating concrete floor can be a real nuisance that can ...

Role of Calcium Chloride in Concrete

Calcium chlorides is used as accelerator in hydration process of cement, leading to quick set of concrete and to get high initial strength concrete. Maximum permissible limit of addition of calcium chloride is 2% in flake form.
