AF / Antifreeze additive (ANTIFREEZE)

• Accelerates the hardening process of the composition
• Can be used at temperatures down to -15°C
• Can be added to SAKRET products - BE, BH, ZM, GMS, RM
• Can be used in reinforced concrete constructions for building mortars and concretes
• Does not contain chlorine ions
• Above 0°C acts as a hardening accelerator
• Lowers the freezing point of water
• For mortars with class higher than M5

Processing 

Surface preparation

• We recommend performing a thermal calculation of the construction to be concreted
• Building elements (blocks, lintels, etc.) must be cleared of ice and snow. The surface temperature must be higher than 0⁰C
• The temperature of mortar or concrete aggregates/binders (sand, crushed stone and cement) should be above 0⁰C
• The temperature of the substrate and formwork should be such that the concrete does not freeze during hardening before reaching the critical or calculated strength

Usage

• The use of the additive does not exempt you from observing the concreting rules in winter conditions
• Mix the antifreeze additive thoroughly before use
• The additive is added together with the water intended for the preparation of concrete or mix
• In the water-cement ratio, calculate the amount of antifreeze additive as part of water
• The temperature of the concrete/mortar mixture at the time of application should be ≥ +8 ⁰C
• After adding the additive, it is recommended to apply the concrete/mortar within 30 minutes if the air temperature is positive
• At negative air temperatures, the start of hardening will be delayed
• Concrete and masonry structures must be immediately covered with waterproofing and heat-insulating material
