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.

How can you make portland cement as quick setting and water resistance cement?

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.

Why Portland cement is called hydraulic cement?

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.

Why is cement called Portland cement?

In 1824 Joseph Aspdin, a British stonemason, obtained a patent for a cement he produced in his kitchen. The inventor heated a mixture of finely ground limestone and clay on his kitchen stove and ground the mixture together into a powder to create a hydraulic cement-one that hardens with the addition of water. He named the product Portland cement because it resembled a stone quarried on the Isle of Portland, off the British coast. With this invention, Aspdin laid the foundation for today's Portland cement industry.

How does Portland cement differ chemically from other cement?

I assume you are contrasting portland cement with fly ash to portland cement with powdered slag? (Fly ash is from coal furnaces, powdered slag is from oil-burning furnaces). Slag is very similar to portland cement, and can be used to cheaply replace up to 50% of portland cement in concrete. This is less expensive, and the slag makes the hardened concrete more resistant to de-icers. Fly ash is not similar to portland cement, but is also good to resist de-icers. But since fly ash is not similar to portland cement, only 20 to 30% of portland cement can be replaced by it. The main difference in chemistry are the amounts of oxygen-containing elements. (Called 'oxides'). For example, portland cement has 65% of C2O, Slag cement has 45%, and Fly ash contains 25% For SiO2 portland cement 20%, Slag cement 33%, and Fly ash 37% For Al2O3 portland cement 4%, Slag cement 10%, Fly ash 16%. There are other very minor differences in chemistry.

Difference between opc and ppc?

Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
