Natural Pozzolan
Pozza is a natural pozzolan used to increase the strength and durability of air-lime or natural hydraulic lime-based mortars.
General Features
-
High-purity natural pozzolan sourced from Turkey.
-
It replaces lime by weight during mortar preparation.
-
It has a very high amorphous SiO₂ content.
-
It is suitable for use in restoration applications.
-
It is used in green buildings.
-
It has a significant effect on final strength.
-
It reduces capillary water absorption.
-
It is gray in color.
-
It has a high 28-day and 90-day activity index.
-
It has a low chloride content.
-
It has a low sulfate content.
Applications
-
It acts as a binder when mixed with slaked or hydraulic lime,
-
and is used in repairs, joint filling, grouting, coarse and fine plasters, and the preparation of Horasan mortars.
