Will be leaving it for a little over a week before we mark out our ICF wall positions, and chemset in internal wall starter bars. By the time we load up the slab, it will have cured for around 4 weeks. I asked the concreter about curing in Melbourne in the middle of winter. They did add a small amount of accelerant to the 33 cubic metre mix as it would take hours for the pour to stiffen up for bull floating, troweling & using the helicopter. Otherwise, they don't do terribly much different provided the concrete pour is suited to the temperature range. I saw the difference with the accelerator when they were a little short on the concrete and ordered a small amount. This was barrowed in but the accelerant wasn't used. They had to wait quite a while for it to firm up. Eventually everything was smoothed over and over and over to a really nice, flat finish, using the laser level at multiple points throughout the process. After they finished, it drizzled, giving the slab a nice shine. No ill effects from the rain after it dried. Just waiting now. When you get a chance watch the last couple of videos. The cracks are pretty bad, it's almost as though he hasn't put any reo in that corner and hasn't compacted/levelled… 2 3358 You are fine. The concrete is never going to explode. Worse case scenario is that it develops a crack from different rates of expansion but hopefully it's got some… 5 4507 |
