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.
âThe results of field and laboratory testing indicated that the compressive strength of the silty clay ranged between 0.5 to 2 tsf.â âThe compressive strength is directly related to the density (lower density equals lower strength) and ranges from as low as 250 psi up to more than 3000 psi.â âThey also have much higher compressive strengths than the concrete mix you are thinking of using.â
