Tension Vs. Compression of Concrete | Hunker
Reinforcing. To give concrete tensile strength to support beams in a bridge or building, for instance reinforcing steel is added. Steel has great tensile strength; it bends without breaking. The combination produces the strength needed for bridge girders, roadways, building walls and other construction.
"Effect Of Salt Water On Compressive Strength Of Concrete"
This paper therefore presents the result and findings of an experimental research on the effect of salt water on compressive strength of concrete. For this concrete cubes were cast using fresh wi and salt water for a design mix of M30 1:: by weight of concrete, and water cement ratio.

The most common test is used for quality control of concrete units is the compressive strength test. The main purpose of compressive strength test is to simulate the actual strength that concrete units will withstand in the field. When we extract core or cast cylinder we do not get smooth even surface on one side and for testing of
Role of Concrete Curing
Compressive strength of concrete cured and maintained at 50 degrees Fahrenheit is expected to gain strength half as quickly as concrete cured at 73 degrees Fahrenheit. In hot weather, curing and protection are critical due to rapid moisture loss from fresh concrete.
