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.

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.
When was cement invented?
In 1824, Joseph Aspdin, a bricklayer and mason in Leeds, England, took out a patent on a hydraulic cement that he called portland cement because its color resembled the stone quarried on the Isle of Portland off the British coast. Aspdin's method involved the careful proportioning of limestone and clay, pulverizing them, and burning the mixture into clinker, which was then ground into finished cement.
What is Portland cement made of?
Portland cement is made of,CaoSiO2Al2O3Fe2O3MgOAlkaliesSO3
What is suitable for reinforced cement concrete slab ordinary portland cement or Portland Pozzolana Cement?
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
What is difference between portland and hydraulic 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.
What are the different types Cement?
There are three different types of cement,Ordinary portland cementPortland pozzolana cementSpecial cements.There are 3 types of cement,OPC (Ordinary Portland cement)PPC (Portland pozzolona cement)Special Cements.There are many types of cement.

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.
