CEM II/A-V 42,5 R is a Portland cement with pozzolans added (silica fly ash, V). It consists of 80%-94% clinker, 6%-20% high quality fly ash, natural gypsum (to regulate the onset of binding) and up to 5% other minor mineral admixtures. The high percentage of clinker ensures high strength values of the concrete, good workability and durability.
Product application
This cement is widely used in the construction of standard buildings 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. Balanced characteristics (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/A-V 42,5 R.

The CE mark is affixed to the packaging and 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).
