what is mean by design concrete

Answer Posted / misbauddin mohammed

There are three stages in concrete's life that need to be
considered when developing the mix: the fresh concrete, the
newly completed concrete, and everything after that for the
rest of its life. The requirements for good performance in
each of these three stages can actually conflict.so we need
to design the concrete acoording to strength reqired for
all the three stages of concrete.
