Design a mix for a 3,000 psi concrete to be used in an indoor
basement slab. Your gravel is an ASTM C33C #57 stone. Your fine
aggregate grades as follows: No. 4 – 3%, No. 8 – 7%, No. 16 – 20%,
No. 30 – 25%, No. 50 – 20%, No. 100 – 15%, Pan – 10%.
What is your mix and list out what you can do to make a durable
mix that is economically competitive? How would you...
