Hi Guys,
We are in the process of converting an old barn into a workshop and are about to put down the concrete floor. It will be going onto shale with hardcore on top, and be 150mm thick. The paln is that the workshop will have a number of reasonably big machines - some woodworking but also some metal working machines. Some of these will be quite heavy, at least 500kg, so the guys who we are looking at getting the concrete from suggested 'CP35 mix' which is supposed to be very strong, and adding polymers (that give a similar effect to adding lots of glass fibres in that they strengthen it further). The polymers were only £5 per cubic m extra, so we will probably go for that (anyone have any experience of these?).
Anyway, the question is, should we add regular farm pig netting to the concrete slab to try and strengthen it up? We have a mass of it just sitting about from some recent fencing jobs and could shove it in there as a sort of poor man's rebar. Some of the rolls are better than others - some have bits of rust - would including these be disastrous? Moreover, would the zinc coating on the rest of it react in any strange ways with the concrete? I have googled to try and find out if other people have done this, but not much luck, so I would be grateful for any input on this...
