CEM II/B-P 32,5 N

Portland pozzolana cement consisting of clinker and natural pozzolana. Best suitable for all kinds of mortars and general construction work. Suitable for low and moderate-strength concrete.

65% ≤ Clinker ≤ 79%;
21% ≤ Natural pozzolana ≤ 35%;
Additional minor constituents ≤ 5%;
Calcium sulphate as setting regulator.
(Natural Pozzolana: Regional Product of the Azores).

Compressive strength

​​

• Low development of early strengh;
• Continuous strength development until 28 days.

• Attend the standard minimum cement content and maximum water/cement ratio;
• Provide adequate protection and cure according to correspondent standards;
• Keep framework and scaolding in place until required compressive strength is obtained;
• Under aggressive environments, strictly follow standard recommendations and technical information about the subject.

• Pre-stressed concrete;
• Rapid hardening concrete;
• Concrete in cold weather.

• Wear proper protective clothing, gloves and eye/face protection equipment;
