North End View of Slab One
This morning we poured the first of the slab layers. No blowouts. Only two small leaks of concrete under the forms along the dirt (~1 or 2 cu-ft) and no collapses. It was a very successful pour and we got it done in only about one hour plus a little cleanup time. We were actually ready a day ahead of time so I called up the concrete people (S. D. Ireland the rock group formally known as S. T. Griswold) and they delivered early.

In a few days we’ll do the next layer, while the concrete is still fresh to make a strong bond. I divided this slab into two layers because we’re doing a 16′ unsupported span beam with wooden forms. While the west half is sitting on a previous insulated concrete slab, there’s no earth under the east section which is about 16′ wide by 32′ long of unsupported form work. 19,200 lbs of concrete is now curing on that large span. With multiple pours in mind we left the top of this layer very rough, raking the top to give it extra grab with the next layer. We also left a ring of steel that will join the two layers. Eventually this thin slab will be the bottom part of a super insulated beam who’s spanning members will be 12′ tall, strong enough to carry far greater loads than we’ll ever have.
We couldn’t have had better weather – cool, in the sixties and overcast with some sun. Just right for pouring concrete.
