Cement IV/B(V) 32.5N

CEMENT CEM IV /B (V) 32.5N ACCORDING EN 197-1 DATA SHEET

Cement is a binder, a finely ground inorganic material which, when mixed with water forms a paste that sets and hardens by means of hydration reactions and processes and, once hardened, retains its strength and stability even under water.
