EP #172: Is Your Concrete Mix Eating Your Formwork?
K
8:31Ken PrattGUEST
or in ohio we're in ohio so let's use ohio because this is real this winter and normally you get on a podium pro shore titan system you might get seven or eight reuses and after two it's looking very worn out and so those areas that jonas just described that chemical reaction is breaking down that surface tension of that overlay breaking down that phenolic and it's literally eating away at it and we've got dozens and dozens of stories at it but now the contractor who had bought the plywood expecting to get seven he's hoping he now can get seven but the concrete doesn't look very good after two or three because the concrete was so harsh now on that particular story when we were looking at the concrete mix i was nervous about recommending high flow and i wanted to move up to our classic which has a lot more alkali resistance which has a lot more durability can handle these harsher more reactive concrete mixes but contractor chose to stay with the BMAT because that's what they've always done.
