Yes. Read the instructions.
ANS 2 - You can, but it has limited uses as it gets quite brittle.
Aggregate (rocks), sand, and portland cement. And water, initially. That's a typical mix.
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.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
one part hydrated lime, three parts medium grade sand, two parts Portland cement and water as required or needed
well concrete mix is a 1/3 gravel , 1/3 sand and 1/3 portland cement . I hope this helps.

Add the water to the cement, a little at a time as you mix.
Cement, or more correctly, Portland cement, named after the person who perfected making it, is essentially limestone that is burned in a kiln, then pulverized to a fine, fine dust. Think of Portland cement as 'Instant limestone', because when you mix it with water, the water chemically combines with the cement to form a hard, hard product that is durable, has high compressive strength, and resembles limestone. After the Portland cement dust is made, it is mixed with a large proportion of clay -- just plain, ordinary potter's clay -- and also a bit of gypsum and other trace ingredients that all work to make the cement set up harder and faster. In concrete, Portland cement makes the concrete "cure", to set up, that is, to chemically combine with the water. The product is a very durable, very strong, very fast-curing aggregate, using sand and stones to fill in between each other and the cement particles.
If you have added too much water to your mix just add more sand and cement ;but do this right away.
Hydration in concrete provides the means with which to mix Portland cement and the aggregates.
Concrete :- a mix of cement, sand, water, and gravel. Mortar :- a mix of cement, sand, and water
Concrete :- a mix of cement, sand, water, and gravel. Mortar :- a mix of cement, sand, and water
You need sand in it. 1 part cement to 2 parts sand.
