There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.

The gravel doesn't effect the tensile strength of the concrete unless you add so much there isn't enough cement paste to fill the voids in the finished concrete, and it merely acts as a filler, taking up space. Adding too much gravel can make it difficult to get a smooth finished surface on the cured concrete.
