This calculator gives you,
Waist slab (ft) = (√(Riser)2 + (Tread)2)
Number of Riser = Height of stair/Riser
Number of Treads = Length of stair/Riser
Volume of 1 step = 0.5 x Riser x Tread x Width of stair
Volume of Total step = Volume of 1 step x No of riser
Length of Waist Slab = (Number of riser x Tread)
Height of Waist Slab
Slant Height of waist slab = (√(Length of waist slab)2 + (Height of waist slab)2)
Volume of Waist slab = Width of stair x Thickness of Waist Slab X Slant Height
Total volume of stair (cft) = Volume of total step + Volume of waist slab
Total volume of stair (cum) = (Volume of total step + Volume of waist slab)/35.315
Dry volume of Stair in Cum = Volume of stair x 1.524
Dry volume of Stair in cft = (Volume of stair x 35.315)
Cement Volume = (Dry volume x Cement)/sum of ratio)
Cement in kgs = (cement volume x 1440)
No of Cement Bags = (Cement Volume/0.035)
Sand Volume in cum= (Dry volume x Sand)/sum of ratio)
Sand Volume in cft = ((Dry volume x Sand)/sum of ratio)) x 35.313
Sand in Kgs = (Sand Volume x 1550)
Sand in Ton = (Sand Volume x 1550)/1000
Aggregate Volume In cum = (Dry volume x Aggregate)/sum of ratio)
Aggregate Volume In cft = (Dry volume x Aggregate)/sum of ratio) x 35.313
Aggregate In Kgs = (Aggregate Volume x 1350)
Aggregate In Ton = (Aggregate Volume x 1350)/1000

GENERAL GUIDELINES:
1. The respective tread and riser dimensions for all the parallel steps should be the same on the consecutive floor of a building.
2. The minimum vertical headroom above any step should be 2 m.
3. Commonly, the number of risers in a flight should be restricted to twelve.
4. The minimum width of stairs should be 850 mm, though it is desirable to have a width between 1.1 to 1.6 m. Large stair widths should be provided in a public buildings, cinema halls, etc.
5. Staircase angle of inclinations should not more than 40 degrees horizontal.

❓ Frequently Asked Questions (FAQ)
What is the ideal concrete mix ratio for general construction?
For general construction purposes, a 1:2:4 mix ratio (cement:sand:aggregate) is commonly used. However, the specific ratio depends on the structural requirements and the grade of concrete specified by the design engineer.
How long does concrete take to cure completely?
Concrete typically reaches about 70% of its strength within 7 days and achieves its design strength (close to 100%) in 28 days under proper curing conditions. However, curing should continue for at least 7 to 14 days for best results.
