how much tensile strength of M20 grade concrete at 28 Days
A concrete strength of 3500 PSI should be just right for a basketball court.
Generally speaking, concrete is rated anywhere from 2000 psi to 10,000 psi. Of course if you do NOT use the proper ratio of aggregate (usually sand) to cement and water you can make concrete that is even weaker. When concrete is ordered from a delivery company, you specify the strength of he mix or pour that you want.
The strength of concrete on the 28th day is considered full strength with regard to the engineering calculations for its use. Concrete continues to get hard for 100 years or more, as long as it has water on it now and then. For a 6-sack concrete mix, its 28 day compressive strength should be at 4,000 psi or greater.

Generally speaking, concrete is rated anywhere from 2000 psi to 10,000 psi.

The weight of concrete is determined by its density, which is typically around 150 lbs/ft³. However, the density of concrete can vary depending on the type and amount of aggregate used, as well as the water-to-cement ratio. Additionally, the weight of concrete can also be affected by the compressive strength of the concrete, with higher strength concrete often weighing more than lower strength concrete. Therefore, the weight of 6,500 psi concrete can vary, but it is typically around 150 lbs/ft

Yes it is. Concrete has almost no tensile strength on its own, which is why some form of reinforcement is used. Generally re-bar, steel shake, or fiber glass is used to improve and reinforce concrete. Epoxy has a tensile strength of at least 2,400 psi. The compressive strength is almost 10,000 psi.

500psi
1 psi = 0.00689475728 MPaAs such the average strength in PSI = (4620 + 4580 + 4400 + 4460 + 4200) / 5= 4452 psiAverage strength in MPa = 4452 x 0.00689475728= 30.69545941056 MPa= 30.7 MPa
3000 psi concrete weighs Approx 3900 Lb/yd3
Concrete is ordered in terms of what strength it will be when it is dried a cured. For instance a typical mixture for an engineered foundation would be 3000 psi. Most driveways are 2500 psi. Check your local codes. Some county's require 3000 psi for the approach and any sidewalk which adjoins their street.
It is exactly 4351 psi but generally referred to as 4500 psi.
