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.
The type of aggregate, the air content, the admixtures, temperature and the proportions of all the ingredients affect slump. The typical slump used for a driveway is five inches plus or minus one. A pound per square inch (psi) is the unit of measurement used to describe the compressive strength of concrete. The most desirable strength for driveways varies based on climatic conditions. In broad terms, the colder the climate the higher the desired psi.
