How is RCC slab area calculated?
In M20 mix concrete M is stand for mix and numerical figure 20 is stand for characteristic of compressive strength 20N/mm2 after mixing and casting of roof slab, quantity of material in slab formation it calculated by M20 mix in which ratio of sand cement and aggregate is 1: 1.5 :3.
What is the area of a slab of concrete?
The amount of concrete you need varies by project. One 80lb-bag covers an area of about 2 square feet, for a slab 4 inches thick. Two 60lb-bags of concrete cover an area of about 2 square feet for a slab that is 6 inches thick.
How is two-way slab calculated?
If the longer span of the slab is ly and the shorter span is lx, then for a two-way slab, ly/lx is less than 2. If the ratio is greater than 2, it is identified as a one-way slab. The two-way slabs distribute the loads in both directions. Hence, the reinforcement is provided along shorter and longer sides of the slabs.
How can I get one way slab?
How do we calculate a one way or two-way slab? If the L/b ratio is greater than or equal to 2 or then it is considered a one-way slab. If the L/b ratio is less than 2 then it is considered a two-way slab.
How do you calculate slab thickness?
Standards like ACI 318 have specified the minimum thickness of the slab based on the span of the slab.
- Simply Supported Slab = Span / 20.
- One End Continuous Slab = Span / 24.
- Both End Continuous Slab = Span / 28.
- Cantiliver = Span / 10.
How do you calculate a concrete slab?
A concrete slab calculator works by calculating the amount of concrete needed in cubic feet by multiplying together the values in feet for the length, width and depth of the concrete slab. The result is divided by 27 to get cubic yards.
How to measure concrete slab?
Determine how thick you want the concrete
How do you figure a concrete pad?
Figure the amount of concrete in a concrete pad. Concrete pads are usually poured for the purpose of parking or for a base for a storage building. To figure the yards of concrete necessary to pour a concrete pad, take the square footage of the pad (length time width) and multiply that by the thickness of the pad.
How do you calculate concrete pad?
Determine the Pad’s Area. Measure the length and width of the top surface of the concrete pad in inches and then multiply them to get the pad’s area in square inches. For example, the length is 20 inches and the width is 15 inches, the area is 300 square inches.
