Using A.A.C. Block

Hi Kay,

Where in the world are you?

Mike

Pennsylvania... We are still using CMU and concrete I understand there is a particular application for AAC Block in mine shafts is this your experience in ohio? Architects are not specifying this material around here for general construction applications.

AAC (Aerated Autoclaved Concrete) is infinitely better than building something with firewood. However, the basic technology is archaic and there are much better and simpler (think more cost effective) ways to do aerated concrete.

Using preformed foam technology is easier, produces a much stronger AND better insulative product, needs no expensive and environmental damaging autoclave. etc, etc,

Just google aerated cellular concrete.

(By the way, when you look at the strength to density given for the portland based aerated concrete, multiply by ten to see what the strength of aerated ceramic cement is.

Please read the chapter 1 of the book titled Developments in the formulation and reinforcement of concrete Edited by Sidney Mindess, Wood Head Publishing in Materials. This chapter is contributed by Prof. R. Klingner, University of Texas at Austin, USA.

Is the Fly ash is better for AAC or Sand?
