Cement Calculator

Calculator Cement, Material
and Cost, for a Project.

### Entry Form

Length: feet

Width: feet

Thickness: Inches

Cost:\$ Per Bag

### Answer

Cubic Yards: Aggregate

Cement: Bags

Cement:\$ Cost

Tax, sand/gravel not
included in cost.

### Using This Cement Calculator.

This calculator is based on
6 - 94 Lb. sacks of Portland
Cement per cubic yard
(3000psi).

27 cubic feet equals
1 cubic yard.

Enter length, width in feet,
and thickness in inches.

Enter cost per bag of
cement.

Round off answer to next
even higher figures.

This calculator is intended for
approximate guidance.

### Working with Concrete Tips

Only use clean water, sand
and gravel.

Aim for a mix of:
1 part cement, 2 part sand
and 3 parts aggregate.

Cement should have a grey
look, if not add more cement.

Mix the dry cement and sand,
add water, mix, then add
aggregate, and more water
as needed.

Water should not be freely
running on top.

Adjust the mix by adding
more water, cement or
sand as needed.

Concrete must be used
within 1-2 hours of mixing,
depending on temperature.

The sooner you work on it
after pouring, the easier
the job.

Avoid over-working any
poured concrete, as this
will weaken the concrete.

Sand shrinks in volume
when water is added,
so think a little more than
the dry volume.

Best time to work concrete
is early morning or late
afternoon, but be aware
there is a waiting time for
surface water to evaporate,
if you wait too long in the
afternoon to do the job,
it could end up late in the
evening, when you will be
troweling the concrete.

It takes a few weeks for
concrete to reach 90
percent of its final strength.

Concrete that cures too fast
will crack, scale, and flake,
and lack strength and
durability.

If the weather is windy or
very hot, cover the concrete
to prevent the quick
evaporation, which can
cause cracks in the concrete.
