UNIVERSAL 32,5 R
Portland-composite cement
The ideal cement for general and minor concrete works where normal final strengths with
medium fast onset are required. The lower development of heat of hydration predetermines
it also for concreting in warm weather.
Universal for general concrete works
CEM II/C-M (S-LL) 32.5 R is a cement made by finely grinding Portland clinker, gypsum and limestone
with blast furnace granulated slag (36-50% according to STN EN 197-5). It achieves a 2-day strength in the range of 14 to 18 MPa and a normalized 28-day strength of 42 to 47 MPa.
