Hi Anthony. Simply specify the required psi when ordering concrete and let them 
know to have the driver bring empty concrete test canisters (two for each 
truckload) with him. Do not pour without the test canisters! This gives the 
concrete company incentive to give you the proper mix. Don't rely on slump...it 
is too qualitative. Then in 30 days have an independent local lab test one 
canister from each load. 

Best regards, 
Scott W3TX
