Portland Cement Volume

Calculate the quantity
of concrete you can produce
according to how many bags
of Portland cement you
have on hand.

Simply input number
of bags of cement.

Volume Calculator.

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

27 cubic feet equals
1 cubic yard.

Enter number of bags
of Portland cement or
fraction of bag.

Example: One and half
bag, Enter 1.5

Working With

Hand Mixing

Only use clean water,
sand and gravel.

Aim for a mix of 1 part
cement, 2-1/4 part sand
and 3 parts aggregate.

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

Cement mix should look
gray, not brown, and
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 2 hours of mixing,
the sooner the better.

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

Sand shrinks in volume
when water is added, so
order 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
toweling the concrete.

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

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
