Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the ...
Compressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

With fair conditions as to the character of the materials and workmanship, a mixture of 1:2:4 concrete should show a compressive strength of 2,000 to 2,300 pounds per square inch in 40 to 60 days; a mixture of 1: 2 1/2: 5 concrete, a strength of 1,800 to 2,000 pounds per square inch; and a mixture of 1:3:6 concrete, a strength of 1,500 to 1,800 pounds per square inch.
In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.
Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.

Mar 20, 2012· Hi all I have a project in which I need to flatten the ends of some 1-1/4 inch SCH 40 (1.66 OD X .140 wall) carbon steel pipe. The flat part needs to be about 4 inches long. My question is how much force will be required to do this? I'm hoping to be able to make a press from a bottle jack to be able to do this but have no idea what size jack will be required.
Although there is additional strength in the bar after yielding (due to Strain Hardening), this additional strength in the bar is not considered in the analysis or design of the reinforced concrete members. In the strength design method, actual loads or working loads are multiplied by load factor to obtain the ultimate design loads.
Jul 04, 2009· However, I came across an Indian code specification that call out this particular 1:2:4 concrete mix as type M15. The number 15 expresses its compressive strength (after a 28 day cure) of 15 N/sq mm, which is equivalent to 2175 psi. What I just stated is that this is the cube compressive strength.

CE 331, Fall 2010 Flexure Strength of Reinforced Concrete Beams 5 / 5 4. Calculate φ (strength reduction factor) φ is a function of the strain in the steel. If the strain in the steel (εs) is at least 2.5 times the yield strain (εy ~= 0.002 = 60 ksi / 29,000ksi = f y / Es), then the max. value of φ = 0.90 can be used.
