Quality
The quality of cements is
supervised by the TSÚS (Building
Testing and Research
Institute), Bratislava.
CEMMAC is a holder of an
ISO 9001: 2008 quality
management certificate
and an ISO 14001: 2004
environmental management
certificate.
The content of tricalcium
aluminate in this cement is less
than 5%.
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.
Characteristics
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 46 MPa.
Usage
- plain concrete and reinforced concrete
- concrete and concrete elements
- concretes of low and medium strength classes
- production of small concrete elements
- underlying concrete and cement screeds
Advantages
- reasonably fast increase in strength
- excellent workability simplifies the placement of concrete and facilitates the smoothing of screeds
- high plasticity improves pumpability and simplifies machine processing of screeds and plasters
- low heat of hydration
- moderately high final strengths
