Concrete \Con*crete"\, v. i. [imp. & p. p. {Concreted}; p. pr &
vb. n. {Concreting}.]
To unite or coalesce, as separate particles, into a mass or
solid body.
[1913 Webster]
Note: Applied to some substances, it is equivalent to
indurate; as, metallic matter concretes into a hard
body; applied to others, it is equivalent to congeal,
thicken, inspissate, coagulate, as in the concretion of
blood. "The blood of some who died of the plague could
not be made to concrete." --Arbuthnot.
