Concrete

It was an early morning. The first truck showed up at 4:45 am. They were pouring 10 min later. The excavator is just there for the lights.

It was a big scene that morning. We have been doing our best to keep the construction traffic localized to the immediate area around the building site to limit the damage caused by such massive equipment. To be honest, I am quite pleased with the results so far.

Here is the inspector performing a "Slump test." He filled the cone with concrete then removed the cone. Next he measured how far down the concrete fell in relation to the top of the cone. Our concrete fell 3.5 inches. This was good and we passed the test. Over 4 inches and we would have failed.

These cylinders are another test. They are filled with concrete and broken on 7, 14, 21, and 28 days after pouring to test the strength. The concrete we poured was 3000 psi. Everyone on site was confident that it would test stronger than that.

Here is some freshly poured concrete. We poured 42 yards, at 10 yards per truck we had 5 trucks that morning.
