CEB Prototype IV Calculations

Basics

• Recommended pressing force depends on brick area
• Recommended force is ______________ for 2", 4", 6" thick brick

pi r squared for the cylinder pressure at 3000 psi yields

3.14 * 2.5^2 * 3000 = 58875 lb

According to Powell and Sons, we need 1200 psi on the brick to press 4" tall bricks - 8x12 bricks

or 1200*12*8 = 115,000 lb

Former work - we made 6x12 bricks - or 86,000 lb
