Rampf Formen presented its new development, the CSi-Nitro concrete block form, with great success at the Big 5 Show in Dubai in late November 2010. Since then, sales of the CSi-Nitro hollow block moulds have risen constantly. The design of the new CSi-Nitro concrete block moulds stands for high standards with regard to resistance to wear, vibration capability and ease of maintenance of steel moulds for hollow and solid blocks.
