RHEOMAC AS 180 

RHEOMAC AS 180 is a dry, highly reactive pozzolanic powder formulated to produce concrete with special performance qualities.  It improves the hardened characteristics of concrete in two ways.  Firstly, RHEOMAC AS 180 is a very fine material that, when added to concrete, physically fills the voids between cement particles.  Secondly, RHEOMAC AS 180 is a pozzolan, which reacts chemically within the concrete to increase the amount of calcium silicate hydrate gel formed.  These physical and chemical changes produce concrete, which has higher strength, low chloride ion diffusion, increased resistance to aggressive materials and reduced permeability.  A strong and extremely durable concrete is the result.
