Peramin® AXL
Peramin AXL - accelerators for mortars and specialty binders
Peramin AXL range of accelerators increase the speed of drying, particularly for formulations containing both calcium aluminate specialty binder and calcium sulfate binders wherein the drying results from the formation of ettringite.
Accelerators are additives that can act in one of two ways, and sometimes both at the same time, they reduce the setting time of mortar or concrete and/or increase the rate of strength development.
Generally speaking, Peramin AXL accelerators are used in fast setting mortars, floor applications and special mortars, in order to reduce construction time. They are also mixed with mortars or concrete that can have longer setting times due to being retarded by another additive, such as cellulose ether, or are placed in cold conditions, in order to avoid freezing before the setting.
There is one main product in Peramin AXL range, Peramin® AXL80. It is specially designed for calcium aluminate specialty binders. Based on lithium sulfate monohydrate it is an excellent alternative to lithium carbonate. It brings faster development of mechanical properties for the same dosage. It confers a better surface aspect, probably due to its higher water solubility.
