Technical Data Sheet Safety Data Sheet Description Pieri® Chromofibre 1B-99 is a pre-blended powder additive developed for exposed aggregate concrete. It combines colouring and performance-enhancing characteristics to improve the appearance, durability, and consistency of decorative concrete surfaces. The product imparts a Basalt Black colour to the cement matrix, helping it harmonise with the natural aggregate and creating a more uniform architectural finish. It also improves concrete cohesion, helping to reduce segregation during transport and placement while promoting a consistent exposed aggregate appearance after washing. In addition, Pieri® Chromofibre 1B-99 contributes to improved freeze/thaw resistance, abrasion resistance, impact resistance, and reduced plastic shrinkage cracking. Application areas Pieri® Chromofibre 1B-99 is suitable for: Low-traffic roads Cycle paths Footpaths and pavements Factory and office walkways Pedestrian crossings Public parks Private roads Public squares and urban landscaping Decorative exposed aggregate concrete applications Benefits Enhances the architectural appearance of exposed aggregate concrete Produces a coloured and homogeneous cement matrix Reduces segregation during transport and placement Improves consistency of the exposed aggregate finish Increases resistance to freeze/thaw cycles Improves abrasion resistance Improves impact resistance Reduces plastic shrinkage cracking Supports durable decorative concrete surfaces
