I put some "how to" videos on my build thread if you want to take a look.

I'm planing on making my own live rock. Would it be okay to use just Portland cement with no oyster shells or crushed coral? Or will that just cause the rock to be very heavy?

Real Live Rock comes from a reef somewhere and contains real animals that can be a real surprise. It is called "Live" because it is and it needs to be kept wet until it is placed in an aquarium for "seasoning". It's value is it's ability to filter water in a salt tank better than any other material.
When you use some man-made material you can do whatever you want. If you are not building a salt tank, I do not think it matters. I cannot speak to the weight of either as I have a salt tank with 600 lbs. of real live rock.

i dont see why you couldnt use the same stuff. i would definetly use white portland thou for fw cause you wont have the coralline algae to change the look of it.

The white cement looks way better I can't find it anywhere in nh tho
