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.
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.

Is there a special type of cement to repair cracking areas around a pool?
There are two types of Portland cement you could use. (white and grey) The color you use is determined by the area you are repairing.If you are repairing the interior finish you should use Portland white cement.(if it is a colored finish you will need to add dye) If you are repairing concrete,shotcrete or gunite you should use Portland grey cement.Keep in mind these cements will cosmetically repair cracks but will not structurally repair them.

Why cement can hard?
Concrete has Portland cement in it. Portland cement is finely ground limestone that is baked until there is no water in it at all. After concrete is poured, the water in it starts chemically combining with the Portland cement, slowly turning it back into limestone . . . sort of. After 3 days, the concrete is hard enough to use . . . walking on or driving on with a light car, but it takes 28 days for concrete to harden to its full rated strength so it is usable in building, bridges, and so on.
What is the suitable mortar for limestone masonry?
I would use type S mortar for vertical applications and portland cement for horizontal work. Portland will work for either but it is rough on your skin and hands.

Cement used for ceramic floor tiles?
Ceramic floor tiles need an acrylic fortified thinset. The acrylic can be added as a liquid or can be already in the mix. There are premixed thinsets available on the market. These are not preferable since they are often not as strong. _________________________________________________________________________________ The cement used for fixing ceramic tiles is white cement or ordinary portland cement. The white cement gives better bonding than the ordinary cement. The use of white cement will not be economical when compared to ordinary cement.
