CONCRETE CALCULATOR FORMULA LENGTH X WIDTH X DEPTH DIVIDED BY 27 OF CUBIC YARDS EXAMPLE 18 FEET LONG 18 FEET WIDE 6 INCHES DEEP THIS WOULD BE 18 X 18 X 527 6 The calculator will estimate the number of cubic yards that will be required Note that this is an estimate There is significant variation in fill space among different blocks This

Apr 18 2018 How to Calculate Concrete Needed To Pour a Slab If your slab has sides of unequal measurement or has cutout areas that will not be poured with concrete youll need to calculate the area of the space to be excluded and then subtract it from the total Next multiply the surface area by the thickness of the slab

Since we know the ratio of cement to sand 12 and cement to aggregate 14 Volume of Sand required would be 00352 007 cubic meter cum Volume of Aggregate required would be 00354 014 cubic meter cum Step2 Convert Volume requirement to weights

Feb 09 2006 Best Answer The ratio I have always used is 123 or 124 those being portland cement sand and gravel It works fine to do this by the shovel full or by the bucket full depending on how much concrete you are trying to mix This mixture will make much better concrete than the
