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.
The force required to break concrete depends on various factors such as the type of concrete, its age, and the specific conditions of the concrete. In general, the compressive strength of concrete is measured in pounds per square inch (psi). For typical concrete mixes, the compressive strength can range from about 2,500 psi to over 10,000 psi. Therefore, the force required to break concrete can vary widely, but it typically takes thousands of pounds of force to break through concrete.
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.

fy= 4000 to 4500 psi
A concrete strength of 3500 PSI should be just right for a basketball court.
Concrete 3000 psi means that the concrete has a compressive strength of 3000 pounds per square inch (psi). This measurement indicates how much pressure the concrete can withstand before cracking or breaking. A higher psi value generally means stronger and more durable concrete.
The force required to break concrete depends on various factors such as the type of concrete, its age, and the specific conditions of the concrete. In general, the compressive strength of concrete is measured in pounds per square inch (psi). For typical concrete mixes, the compressive strength can range from about 2,500 psi to over 10,000 psi. Therefore, the force required to break concrete can vary widely, but it typically takes thousands of pounds of force to break through concrete.
C-40 concrete has a characteristic compressive strength of 40 MPa (megapascals). To convert this to psi (pounds per square inch), you can use the conversion factor where 1 MPa is approximately equal to 145.038 psi. Therefore, C-40 concrete is equivalent to about 5,800 psi.
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 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
M40 is a concrete mix design that typically has a compressive strength of 4,000 psi (pounds per square inch) at 28 days.
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.
500psi
8000 psi (pounds per square inch) is a measure of pressure that indicates a very high strength level, commonly found in materials like high-strength concrete or specialized steel. For context, standard concrete typically has a compressive strength of around 3000 to 4000 psi, making 8000 psi significantly stronger. This level of pressure can withstand heavy loads and is often used in construction and engineering applications requiring durability and resilience.
