Decide
whether to mix on the job or order readymixed concrete.
Select
a concrete mix suitable for its intended application.
Use
cement you can trust - Irish Cement is well tried under Irish conditions and is
supported by an advisory service to assist farmers with any technical or practical
queries that may arise.
Concrete is made by mixing stone
and sand with cement and water in carefully selected proportions and allowing the
compacted material to set and harden. As setting and hardening are chemical processes, it
is important that concrete is prevented from rapidly drying out after placing otherwise
strength development may be impaired.
Properties of concrete are to a large extent dependent on the quality of the sand and
coarse aggregate used and for this reason it is important that only materials free from
clay or other forms of contamination be used.
For very small quantities, it may be appropriate to mix concrete on the job, but where
larger volumes are involved readymixed concrete ensures better quality and is recommended.
