Chloride-Free Liquid Admixture for Enhanced Mortar Workability. Biokil Crown Mortar Plasticiser is a chloride-free liquid admixture conforming to BS 4887, formulated to improve the workability and durability of bricklaying and rendering mortars. By entraining air into the mix, it enhances frost resistance and reduces the risk of shrinkage and cracking. This admixture is suitable for use in cement, sand-cement, and lime-sand mortars, providing a more cohesive and workable mix.. Key Features & Benefits. Improved Workability: Enhances the plasticity of mortar, making it easier to apply and spread.. Frost Resistance: Air entrainment improves resistance to freeze-thaw cycles, reducing the risk of frost damage.. Reduced Shrinkage: Minimizes the occurrence of shrinkage and cracking in the mortar.. Chloride-Free: Safe for use with steel-reinforced structures, preventing corrosion.. Conforms to Standards: Meets the requirements of BS 4887 for mortar admixtures.. Product Details. Packaging: Available in 5 Litre, 25 Litre, and 200 Litre containers.. Appearance: Brown liquid.. pH: Approximately 6.5–7.5 at 5% dilution.. Specific Gravity: Approximately 1.04 at 20°C..
