(0.45/2)2 x pi x 2 = 1/3rd of a cubic meter
It depends on the depth to which the area is filled.

I'll make the assumption that 150 is meant to be metres. 150x6 is 900, x 2.5 is 2250
You can use a concrete crack filler to fill concrete cracks.
A cubic meter of concrete is equivalent to 1,000 liters. An 8-inch form has a cross-sectional area of approximately 0.44 square meters (since 8 inches is about 0.203 meters). Therefore, a cubic meter of concrete would fill an 8-inch form for about 2.27 meters in length (1,000 liters / 0.44 square meters).
You can use a concrete patching compound or a concrete caulk to fill in cracks in concrete. These products are specifically designed to repair and seal cracks in concrete surfaces.
We need to know the dimensions of the tube. The diameter AND the length of the tube. It takes o.465 yards per foot of length for a tube 4 feet in diameter. .
The volume in the pipe is pi times diameter squared/4 times the length. Eight inch diameter = 2/3 ft so volume is 59.31 cubic feet. Since 27 cu ft = 1 yard then that is 59.31/27 = 2.2 yards of concrete
With a concrete crack filler
To fill 0.2 cubic meters, you will need about 21.6 bags. According to the site at the related link, a 20 kg or 40 lb bag of premixed concrete should fill an area of 1/3 cubic foot, which is 1/106th of a cubic meter. There is also a separate estimate of 108 20-kg bags per cubic meter, which provides essentially the same result.
