What are recommended mix proportions for good concrete?
Good concrete can be obtained by using a wide variety of mix proportions if proper mix design procedures are used. A good general rule to use is the rule of 6's:
HINT: 1. A minimum cement content of 6 bags per cubic yard of concrete 2. A maximum water content of 6 gallons per bag of cement 3. A curing period (keeping concrete moist) a minimum of 6 days 4. An air content of 6 percent (if concrete will be subject to freezing and thawing) 5. All of the above
