How to make hydraulic cement.Stir dry in a wheel barrel.
50 lb bag portland
80 lb bag masonry cement
50 lb bag play sand or silica sand
15 lb Plaster of Paris or Molding Plaster
Note: Be sure all the plaster is displaced evenly throughout the barrel.
Scoop out the amount you need and just add water.
Work quickly to mix water with hydraulic material
Stir immediately!
Fast-setting - sets in 3-5 minutes
Performance - instantly stops seepage
Pre-blended - just add water

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.
Hydraulic cements are material that set and harden after being combined with water as a result of chemical reaction with the mixing water, and that after hardening retain strength and stability even under water. Non-hydraulic cement include such materials such as plaster of paris, which must be kept dry in order to gain strength .
Portland Cement is classified as "hydraulic" cement because it cures or solidifies due to its chemical exchange with water, stemming from the building material's ability capability to set under water. In the well industry Portland Cement can be placed or pumped into voids at thousands of feet in depth. As long as the mixture is released or pumped without significant breakdown of the mixture due to water flow the cement will cure just as well we see during ground level applications.
limestone is used to make cement
Am not a 100% sure about this answer but yes it does hold some water in it, the portland cement majorly has its use in well aerated places i.e its mainly used for construction above sea or simply iits used where cement can dry in air but the hydraulic has properties enabling it to harden properly under water. and thats where its mostly used or in places where water really comes around.

hydraulic cement, after the combination is grind ed into a fine powder!

Cementuous materials are not waterproof. Hydraulic cement is the closest they come, but even it becomes saturated.

No. Cement is a mixture of several elements and water. Hydraulic cement is made from limestone, clay, and gypsum.
limestone is used to make cement
A small cement silo works by storing dry cement powder and releasing it into a mixer or conveyor system through a controlled discharge mechanism. The silo typically has an aeration system to prevent clogging and ensure a consistent flow of cement. The cement is loaded from the top and can be unloaded from the bottom through a screw conveyor or air slides.
Limestone is refined to make portland cement.
clay + limestone = cement
