Cement
I don't know where the term came from, but it is replacing cement between bricks. Usually, this is on older buildings where the cement has fallen out. Using a pointed trowel, the cement is replaced. This prevents leaks and other structural problems.
Please note that a key correction in terminology is essential before your question can be answered: use the word "concrete" instead of "cement." The answer is to modify your mix (i.e. Portland cement, sand, gravel, and water) by using hydraulic cement to repace part of the Portland cement. The higher the amount of hydraulic cement you add, the quicker the setting time and the impermeability. However, hydraulic cement sets so quickly that you have limit the amount of total mix so as to be able to pour it and form it before it sets.
Before the invention of the rotary kiln, cement production was a much more laborious process. It was usually stirred continuously in a wheelbarrow or other receptacle.
