Higher cement content mixes are generally easier to pump. The difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete; while sand is abrasive

Rotary kiln - Wikipedia

The refractory selected depends upon the temperature inside the kiln and the chemical nature of the material being processed. In some processes, such as cement, the refractory life is prolonged by maintaining a coating of the processed material on the refractory surface. The thickness of the lining is generally in the range 80 to 300 mm.

Concrete Mix Design Procedure and Example IS456

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
