Re: SB: RE: RE: mistake with lime

[douglasr@softhome.net]

Portland cement mix burning to the bone? Whoa, am I misreading, or just 
possibly dead and haven't noticed? I've poured enough concrete over quite a 
number of years to be able to swear I can hear the truck leaving the cement 
plant 1-1/2 miles away and feel it driving down the road while I am 
frantically driving the last stakes. I have been up to my elbows in the 
stuff, jeans soaked through, etc., spattered and splashed onto my face and 
eyes. I've poured in cold weather, hot weather, everything in between. I'm 
not missing body parts (ok, brain may be slightly damaged) or skin. The 
worst I have ever felt is mild discomfort which has been relieved by washing 
up. 

I don't doubt anyone else's experience but I wonder if I am hearing the same 
thing that others are talking about? I can't see that a standard 
sand/gravel/portland cement/water mix is remotely hazardous or anything 
beyond "not recommended for prolonged skin contact." But again, maybe I'm 
not catching the argument and would be happy to be corrected.
