Heavy works

Everyday we have a lot of works to do in NR.
 
We need to take sample pieces every time, at the construction site. There are some types of sample figure. Round, square, plane and so on. One of them give us a pain that pick it up. We call it “A bending sample”.

Why is it? That’s because it’s too heavy to bring alone. The mold is square type and cast in iron. This size is bigger than other round type molds. One testing uses three pieces and it need to check at 7 days and 28 days. So we must take six pieces at least for strength testing.

I weighed it before putting mold and figured sample. It was fifty-five kilograms weight totally. 55 kg is about 120 pounds, you know. This weight is like one man. It was heavy work and real, too.

After take them off from the iron mold, those are put into pool. One week and four weeks later, we will bring them up again from water. A pressure machine needs to set up for bending system, too. Well, it is such a heavy work for us.
