SikaCem Fibre 12 is a 12mm long, micro-synthetic, monofilament polypropylene fibre used as an additive for concrete, screeds, renders, and mortars. Its primary purpose is to control and minimize plastic shrinkage and settlement cracking that can occur while cementitious materials are still in their fresh, wet state.
Performance: By forming a dense, interlocking matrix within the mixture, the fibres provide several key benefits:
Reduces plastic and drying shrinkage cracking.
Enhances surface properties and improves durability.
Increases impact resistance.
Reduces permeability and improves waterproofing.
