Features of concrete

img26 (3)Fresh concrete should have adequate workability and fluidity.

In this regard, concrete is distinguished:
a) killer, containing a minimum of water,
b) plastic (semi-liquid), with more water,
c) liquid (mastic), whose degree of dilution is this, that it causes the mass to flow under its own weight and thus easier to fill the mold,
d) vibrated, i.e.. tampable or malleable, made to vibrate with vibrators, thanks to which, without further admixtures, water becomes liquid for the time.
