A 4" thick concrete slab reinforced with 6 x 6 x 10 welded wire mesh placed over a 6 ml vapor barrier on 6" of levelled and compacted gravel or sand is common for many residential applications.
I'm assuming there are no point loads anywhere in the slab interior and the slab is used for general purposes such as a residential basement, workshop, or garage floor. Any special circumstances should be engineered.
All steps in the process are important, but one often overlooked is that the base needs to be properly compacted and prepared. A good base will be very level and very well-compacted. If the base is poor, the slab may need to be thicker or engineered. Slabs will crack where the thickness changes and stress forces become concentrated while it's curing and then while it's settling. If you have posts coming down anywhere in the field of the slab, be sure to cut control joints around them and across the slab to direct the inevitable cracks during curing and settling. Control joints are best when they are saw-cut to 1/3 the depth of the slab after the slab has set, and generally spaced 10-12' apart is good. Trowelled-in control joints do not work nearly as well as saw-cut.
Also, remember to use an isolation material such as conventional felt strips at the slab edge to prevent mechanical bonding to adjacent walls and allow for slight differential movement.

How many yards of crushed concrete do you need for a 150'x12' driveway?
Crushed concrete is sold by the ton. One dumptruck will haul between 13 and 15 tons. Your driveway should take around 30 tons if covered 4" thick.
How much does 30 square foot of concrete weigh?
It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.
What is m 30 concrete?
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
What area will 1 ton of crushed concrete cover?
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.

How many yards of concrete in a 20ft by 30 ft slab 5 inches thick?
9.3 cubic yards of cement is required for this slab.
How much concrete for a 28 by 30 slab?
To calculate the amount of concrete needed for a 28 by 30 slab, first determine the slab's thickness. For example, if the slab is 4 inches thick (0.33 feet), the volume in cubic feet is 28 ft × 30 ft × 0.33 ft = 277.2 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need approximately 10.3 cubic yards of concrete for the slab. Always consider ordering a little extra to account for spillage and variations in thickness.
How much concrete 30'x40'?
To calculate the amount of concrete needed for a 30'x40' slab, you first need to determine the thickness of the slab. For example, if the slab is 4 inches thick, convert the dimensions to feet (30' x 40' x 0.33' for 4 inches). Then, multiply the length, width, and thickness: 30 x 40 x 0.33 = 396 cubic feet. To convert cubic feet to cubic yards, divide by 27, resulting in approximately 14.67 cubic yards of concrete needed.
How much does a 10' x 30' x 4 slab of concrete weigh?
10-ft x 30-ft x 4-in = 100 cubic ft.That slab weighs 3.7 times as much as 1 "yard" of concrete. (rounded)
How many yards of concrete needed for 24' X 30' X 6 slab?
To calculate the amount of concrete needed for a slab, you can use the formula: volume = length × width × depth. For a 24' x 30' slab with a depth of 6 inches (0.5 feet), the volume is 24 × 30 × 0.5 = 360 cubic feet. Since there are 27 cubic feet in a cubic yard, you would divide 360 by 27, resulting in approximately 13.33 cubic yards of concrete needed for the slab.
How much concrete do you need for a 62ft x 30ft 5 in thick?
To calculate the amount of concrete needed, first convert all measurements to feet. The volume of concrete required can be found using the formula for volume: length × width × height. For a slab that is 62 feet long, 30 feet wide, and 5 inches thick (which is 5/12 feet), the volume is 62 × 30 × (5/12) = 155 cubic feet. Therefore, you will need approximately 155 cubic feet of concrete.
How many yards of concrete it will take to pour a concrete slab that is 30 ft x 10 ft x 4 inches thick?
3.70 yards and you will order 4 yards to have enough. (30 x 10 x 1/3) = 100 cubic feet Divided by 27 = 3.704 cubic yards
How many yards of concrete fo a slab 30x30x4 thick?
If the units are 30 ft x 30 ft x 4 inches, then you have 30 x 30 x 0.33 ft = 300 cubic feet300 cubic ft/27 cu yds/cu ft = 11.1 cubic yards
How many 80 lb bag cement to make 10x12 slab 3in thick?
To calculate the number of 80 lb bags of cement needed for a 10x12 foot slab that is 3 inches thick, first determine the volume of the slab in cubic feet: 10 ft x 12 ft x (3/12) ft = 30 cubic feet. One 80 lb bag of cement typically yields about 0.6 cubic feet of concrete. Therefore, you would need approximately 30 / 0.6 = 50 bags of 80 lb cement to complete the slab.
How many yards of concrete will a 20 by 30 slab need?
To calculate the amount of concrete needed for a 20 by 30 slab, first determine the area in square feet: 20 feet × 30 feet = 600 square feet. If the slab is, for example, 4 inches thick, convert the thickness to feet (4 inches ÷ 12 inches/foot = 0.33 feet). The volume in cubic feet is then 600 square feet × 0.33 feet = 198 cubic feet. Finally, convert cubic feet to cubic yards by dividing by 27 (since there are 27 cubic feet in a cubic yard): 198 ÷ 27 ≈ 7.33 cubic yards of concrete needed.
