Apr 23, 2018· Estimating concrete steps. Steps seem tricky to calculate but are not. If there are three steps leading up to a porch: Use the slab calculator to figure the concrete needed for the porch surface. Use the footing calculator to calculate the sides of the porch and the steps; Here is an example:

High strength concrete would be mixed using 1 part cement to 5 parts ballast – this affords the sort of watertight concrete used for building slabs or concrete panels. Mixing 1 part cement to 6 parts ballast creates concrete suitable for driveways, paths and patios, and increasing the ratio to 1:8 gives foundationstrength concrete.

Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. The volumetric mix ratio of M20 concrete is 1::3, hence 1 part of cement, part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete.

To calculate the amount of ballast you will need find the weight of concrete required. To do this multiply the cubic meters by which will give you the weight of the concrete required in metric tonnes. With a standard 3 in 1 sub ground concrete mix, (3 parts ballast to 1 part cement), each 850kg bag of ballast will account for 1150 kg of ...
