Cement dust in living space?

I had my cement block foundation replaced with a poured foundation,and it was done in the winter. I was told I could stay in my home, during renovation. I also was told,that the heat would be on.

First off, I ended up in a hospital, sick from a power saw leaking gas, and not venting my furnace or dryer. I left the home, to come back when they were done, to find concrete dust in my air ducts, all over everything in my home, dishes, clothing, walls, furniture, etc.)

I had to get a cleaning renovation company, that cost me, 6,000.00,out of pocket to clean, and still getting dust. I have been told this is standard for pouring a foundation, by another builder. I have also been told, that the contractor should of turned the heat off, sealed the ducts, when he was cutting, etc. to prevent the nightmare I am dealing with. The concrete dust was thick in the basement, as he didn't even clean.

Please advise me. I knew it would be messy, but never thought my health would be compromised, as I know have breathing problems, and had to deal with this mess.

Thanks.
