Super-Pozz® is a highly reactive ultra-fine pozzolan which improves workability, strength and lowers permeability. Tests have shown that Super-Pozz® can produce concrete with comparable strength and durability performance to that achieved with other highly reactive pozzolans such as silica fume.

What Super-Pozz® is not?
Super-Pozz® is more than just another pozzolan. With its unique chemistry, high reactivity and ultra fine particle size, Super-Pozz® can produce concrete with superior technical performance. Unlike silica fume, which increases water demand, Super-Pozz® actively reduces water demand producing higher strengths. This property coupled with its high pozzolanicity and efficient cementitious binder packing, produces a dense, impermeable concrete with improved durability.Super-Pozz® reacts with the free lime (calcium hydroxide) produced by hydrating cement; resulting in the formation of additional calcium silicate hydrate (CSH) gel.

Super-Pozz® can be used in various cementitious applications like high performance concrete, precast concrete, ready-mix concrete, pre-bag formulations, self-compacting and sprayed concrete applications.

The Main benefits of using Super-Pozz® are:
»Reduced water demand of a concrete mix
»Use of more cost effective admixtures dosages
»Improved workability and flow characteristics
»Higher early strengths resulting from lower w/c ratio
»Better ultimate strengths
»Increased durability
»Good surface finish
»Reduced shrinkage
