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.
Concrete. 3000 psi concrete mix is the standard mix that is most widely used and reaches a compressive strength of 3,000 psi (20.7 MPa) in 28 days. This concrete strength is used in most residential and commercial applications. 4000 psi concrete mix reaches a compressive strength of 4,000 psi or (28 MPa) .
