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.
How do you measure poured concrete PSI? Your best bet would be to find a small concrete contractor or someone that works for a contractor since it is not a big job. - Check around loacally or the yellow pages. He should have saw to cut out the existing and remove the excess soil. Then he can pour using bagged concrete mix (3000 psi would be adequate). If you really need them 3' square, put 3 or 4 rebars (1/2) each way. Judging from the size of what you have got listed, a 3 thick floor would be a little marginal.
