Expanding admixture

Everyday we have a lot of works to do in NR.
 
Sometime our customer wants to mix to fresh concrete another admixture. Fiber, binder, expanding material and so on.

Last day, NR had the case of powder expanding. It is not simple works. It needs to lift many bags up to the batch tower with hoist crane the day before. The work needs two guys at least on the ground and on top.

And more, it needs a man throwing the powder above the batcher mixer while make it. A machine operator gives him a sign, then the powder is thrown to batch. He should do it every batch with dust mask. If he doesn’t put  the mask on, he couldn’t be there only one minute. So that’s very hard and tired work.

We are taking products for customer pleasure. When they got a good job, we got pleasure, too. But it is not an easy way for all of us.
