How do you do the treads on a cement staircase?

My house has recently been renovated, I see how our cement cement masters do it, I describe to you, I hope to help you!

The first step is to ask the carpenter to nail out a slope, the second part, cement workers in this slope to tie up the rebar, the spacing of about 20 cm or so square; the third part of the carpentry and then let the shape of the stairs, the fourth part of the cement workers to mix the cement material, roughly crushed stone, sand, cement 1:1:1 ratio it, add water and mix it evenly, and then the material is imported into the nailed wooden mold, and so on solidification. If the weather is good, it will be hard in about 2-3 days. At this time, then scrape the surface with cement, do leveling. Well, finished. After doing so, if it is outdoor, when the weather is hot, water 1-3 times a day, do maintenance, so that the stairs will be firm.
