CEM III/A 32,5 R
all-purpose cement
All-purpose quick-setting cement with an exceptionally good workability and soundness, designed for all types of concretes and mortars in residential construction.
All-purpose cement for private residential construction
CEM III/A 32,5R is a cement with a faster increase in early strengths with a very good workability. It attains early strengths after 2 days ranging from 12 to 15 MPa and standard 28-day strength of 45 to 50 MPa, meaning that this cement highly exceeds the minimum strengths set by the standard.

- plain concrete and reinforced concrete
- concrete surfaces, subconcrete
- foundations and bed slabs
- the faster increase in the early strengths enables a quick walk-on-ability of the surfaces produced
- its excellent workability facilitates the placing and compaction of concretes and facilitates the smoothing of screeds
- its high plasticity improves the pumpability of concretes, screeds and mortars, and also enables machining
- an optimum combination of the quantities of its components improves the watertightness of concretes and the mechanical bond
- the lower development of heat of hydration predetermines it to working even in warm weather
The quality of cements is supervised by TSÚS Bratislava. CEMMAC holds an ISO 9001:2008 Quality Management certificate and an ISO 14001:2004 Environmental Management certificate.
