Allow 625g per person. Roast for 15 minutes per 450g. Roast at 230Â°C/fan210Â°C/gas 8 for the first 20 minutes, then decrease the oven temperature to 180Â°C/ fan160Â°C/gas 4 for the remaining cooking time. Allow 575g per person.
the 5,000 psi is the amount of pressure the concrete can withstand  before it will crush. it has nothing to do with water proofing. to  find out if you need water proofing y â¦ ou need to know how poores the  concrete is and how quickly the ground out side will drain water.
A: The density of normal concrete is about 145 pounds per cubic foot. The density of concrete is determined largely by the type of aggregate used in the mixture. The density of the cement used in the mix can also affect density, with compressed, vibrated cement creating a denser concrete mix.
