- £3.57 - £17.33 ex. VATAlphaChem Accelerator, Frostproofer & Hardener is a heat‐generating accelerator for cement-based mixes. Its principal uses are to facilitate the production of high early strength concrete, cement render and mortar. It is suitable for use as an aid to cold weather working when the heat generated will offset the retarding effect of low temperatures.AlphaChem Accelerator, Frostproofer & Hardener is based on calcium chloride and surfactants and is therefore not suitable for use in structures that are reinforced with steel. Neither should it be used in mortar in contact withSelect options This product has multiple variants. The options may be chosen on the product page
