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.
Most concrete achieves 40-50% of its strength (1500 PSI if its 3000 mix and 2000 for a 4000 mix) within 48 hours. The reason most concrete guys like to pull forms the following day is so they can move onto the next job with their forms and the concrete will continue to strengthen.
