Product Overview

Sika Fiber-PP consists of specially treated, alkali-resistant monofilament polypropylene fibres that are added directly to concrete at the batching plant or mixer drum. When uniformly dispersed throughout the concrete matrix, these micro-fibres act as a three-dimensional reinforcement network that inhibits the propagation of plastic shrinkage micro-cracks before the concrete has achieved sufficient tensile strength to resist them on its own. This is particularly important in Indian site conditions where hot weather, wind, and low humidity accelerate surface evaporation and promote plastic shrinkage cracking in the critical hours after concrete placing. Sika Fiber-PP also improves concrete toughness and impact resistance in the hardened state. It is compatible with all standard admixtures and concrete mix designs and does not affect compressive strength at recommended dosages. Space Arc Engineering distributes Sika Fiber-PP for concrete floor, roof slab, and pavement projects across Delhi NCR and UP.
