In line with our commitment to continuous improvement and meeting user needs, we have developed CEM II/A-LL 42,5 R. In addition to its strength class of 42,5 MPa, this cement belongs to the high early strength class (R). The presence of fine ground limestone enhances the plasticity and cohesion of concrete mixes. It improves flow properties, making pumping and placement easier, especially in high-rise buildings. Additionally, it has a reduced water-cement ratio, which enhances the overall durability of the structure. The addition of limestone (LL) reduces the clinker content, which simultaneously has a positive impact on global CO₂ emissions compared to CEM I (ordinary Portland cement).
Product application
This cement is widely used in the construction of standard structures for any purpose (infrastructure, industry, housing, etc.), both for reinforced concrete and mass concrete structures. Ready-mix concrete plants are the largest users of this cement for concrete strength grades up to C40/50. Its balanced properties (hardness, setting time, heat during hydration) make this cement applicable in all climates and aggressive exposure classes. All standard concrete additives (retarders, plasticizers, etc.) can be used with our CEM II/B-P 42,5 R.
Declaration of Performance and CE marking
Our cements comply with the MKC EN 197-1 harmonized European standard and are subject to assessment and performance verification procedures by a third party (an EU authorized body under System 1+ for assessment and verification of consistency of performance).
The Declaration of Performance on the key product attributes and the CE mark can be found here.
The CE mark is affixed to the packaging and to the shipping documents in accordance with the Construction Products Regulation.
Health and safety
Contact with wet cement, wet concrete, may cause irritation, dermatitis or severe chemical burns. Cement dust coming into contact with bodily fluids (such as sweat or tears) may cause irritation, dermatitis or burns. This carries a serious risk of eye damage. Wear appropriate, impermeable clothing, gloves and eye and face protection. In case of contact with the eyes, rinse them immediately with plenty of clean water and seek medical help. After skin contact, rinse immediately with plenty of clean water. Keep out of reach of children. Contains chromium (VI). May cause allergic reactions, the risk of which is higher if the cement is used past the expiration date stated on the package and the shipping documents.
