A typical mixture of concrete will be 10 to 15% cement, 60 to 75% aggregate, and 15 to 20% water.
It depends on the mixture of concrete. some concretes can float and some are extremely dense. The density of a concrete is dependent on the material it is made from, typically the aggregate. So without a known density for the concrete this cannot be answered.
4000% of 4000 =4000/100 * 4000 =160,000
That's going to depend on many things you haven't mentioned, including how deep/thick you need it to be.
1403.5% of 4000= 3.5% * 4000= 0.035 * 4000= 140

Start with 2000 of P then add 1000 of S an at the end add 1000 of I mix it very good .After about 45 days you will have 4000 p,s and I which stand for 4000 PSI
Aprox. 485 lbs. per Cubic Yard
there is no such thing. psi is how much oxygen is in a certain amount of space (mostly used for deep divers
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.
Concrete is a mixture
3000 psi concrete weighs Approx 3900 Lb/yd3
Concrete is a mixture not a compound.
Concrete is a heterogeneous mixture.
It is exactly 4351 psi but generally referred to as 4500 psi.
