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.
M40 is a concrete mix design that typically has a compressive strength of 4,000 psi (pounds per square inch) at 28 days.
psi = pounds per square inch There are (12*12) 144 square inches in a square foot, and you are going from the smaller unit to a larger one, so divide. 3000 / 144 = 20.833 pounds per square foot. ■ ^^^^other guy... wrong... you are not converting from smaller to larger, it is PER inch to PER foot. 3000 * 144 = 432000 lb/ft^2
In the book "Freakling" by Lana Krumwiede, "psi" refers to the main character's telekinetic abilities. In this story, psi is a term used to describe the characters who possess psychic powers, such as telekinesis, telepathy, and mind control. The protagonist, Taemon, grapples with his psi abilities and the society that fears and segregates those who have them.
One standard atmosphere is equivalent to 14.7 psi.
50 psi of air is equivalent to 1145.037 psi of water.
3000 psi concrete weighs Approx 3900 Lb/yd3
If is standard concrete it is usually 3000 psi mix

The number of bags of cement needed for a 3000 psi concrete mix can vary depending on the specific mix design, but a common ratio is approximately 1 bag of cement (94 lbs) for every 1 cubic yard of concrete. A typical mix for 3000 psi concrete might use a 1:2:3 ratio of cement, sand, and gravel. Therefore, for a cubic yard of 3000 psi concrete, you would typically use one bag of cement. However, for precise calculations, it's best to consult a concrete mix design guide or professional.
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.
3000 psi. with 3/4 rock should do it . but you could go higher psi which would be over kill.

I estimate the price of 3000 PSI concrete is central Florida to be around $80- $85 per CY. I live in north Florida and the price is slightly higher here.
It is exactly 4351 psi but generally referred to as 4500 psi.
