Strength results are also used for evaluating mix designs. Cylinders are usually tested in pairs to verify results and to rule out erroneous information based on unsatisfactory breaks. The objective of compressive-strength testing of concrete cylinders is to determine the amount of force it takes to break a cylinder of concrete. A test

The design (target) binder content is shown in the JMF. The design binder content mixed with the design aggregate structure should result in mix volumetrics that meet specifications. The JMF must have an allowable tolerance on the binder content, usually on the order of ± 0.3 percent to ± 0.4 percent. Are the results reasonable?

concrete. A properly proportioned concrete mix should possess these qualities: 1. Acceptable workability of the freshly mixed concrete 2. Durability, strength, and uniform appearance of the hardened concrete 3. Economy Understanding the basic principles of mixture design is as important as the actual calculations used to establish mix proportions.
