[papercreters] Re: mix

Judith, Hello -your flyash is pozzolan or amorphous aluminum silicate, flyash is low reactivity hence your 40% add ratio -that is OK though since flyash is also aggregate. I use high reactivity Metakaolin clay from South Carolina - sometimes its a matter of access. The reaction we are concerned with is that of the un reacted lime, left over from the portland crystalization process. That lime holds water (the enemy of papercrete) - react that lime with pozzolan and you gain high quality alumino-silicate cement voila win/ win. As to wether I am being reactive to moisture problems, only that in a rooms by the night scenario that is a lot of showers and steam in a papercrete room. You are doing great with your flyash - dont breath it - Thank You for being the papercrete Goddess - Clyde
