C10/C15
Both
these mixes can be used as foundation or footing mixes, for non-load
bearing walls, garden walls up to 900mm high and footing mixes for
house construction.
C20
This
mix is used for footings in house construction, where the ground is
soft or unstable. It can also be used as the slab foundation for the
floors of houses and bungalows, also as a base for hard-standings and
pathways.
C25
This
level of mix may be required as slab foundation for houses or
bungalows. It is also used when replacing or making good existing
floors. It is also used in farming as a general yard mix, as it is
strong enough to support light machinery and livestock usage.
C30/C35
These
are structural concrete mixes for roadways, access to farms or anywhere
where large, heavy vehicles require access on a regular basis. Durable
mixes to withstand heavy wear and strong enough to withstand the
ever-changing climate, continuous heavy rain, frosts, snow and
prolonged dry periods.
C40/45
Used widely in farming, for the construction of slurry and silage pits.
In this environment it is required to have the strength to contain
tonnes of waste product and a strong mix (i.e. cement content) to
withstand the acids and chemicals produced by the content, which often
stays in the pits for long periods of time.
