Chromate poisoning from concrete work
Current posting:
A. I read the question about Tracie's husband's skin condition and wanted to reply. My husband, a concrete finisher for over 20 years, had started getting boils all over his body also, and multiple visits to the doctor and ER. I called poison control; they said he was in the second stage of concrete poisoning and said he can never be around it again or it will keep happening, so he had to quit his profession.
After a year or more the boils went away, but unfortunately a terrible nerve condition started happening to where his legs muscle spasm, his feet cramp burn and twitch, he is finally going to see a neurologist, but I am sure he has chromate poisoning. Also he had blood work to check for metals; we don't have results yet, but this has been a long hard road since he doesn't have any income. He had to file for disability but has won his case yet. Wet Portland Cement is highly dangerous.

A. My husband worked in concrete for over twenty years he started developing sores puss filled pockets as they oozed out there was actually grey concrete and small string like fibers coming out of them, I called poison control they said he has chromate poisoning and to never be around Wet Portland Cement again, which he had to quit he also had one by his eye that sent him ambulanced to the hospital with a 5 day stay, if the infection would of gotten in his eye it would of went to his brain and would of caused him to loose his speech, very scary, he was put on lots of antibiotics, and it finally went away, he then continued to get the boils two years after not being around the cement, now unfortunately he has developed a neurology problem and can barely walk, now we are waiting on blood work to come back from metals and hexavalent chromate. We have been through this for over 3 years.

Q. My son works in concrete. He developed a bad skin condition. He had a terrible time with the company they refused him workers compensation and gave him unemployment finally but he wants to know if this is life threatening and how can he get rid of it short of not working in concrete?

A. The doctor is out.
Please don't rely on strangers on the Internet as to whether an illness your son is suffering is life-threatening. Please get him to a dermatologist ASAP.
I didn't know that concrete included chromate until looking into your posting.
I wish a concrete engineer would join this thread because we metal finishers don't know enough about it. I find that, yes, Portland cement contains chromate, and additional chromate has sometimes been added to help protect the reinforcing steel from corrosion. Additionally, ferrous sulfate
⇦ this on
eBay or
Amazon [affil links] s or other reduction agents have sometimes been used to reduce the chromate content. It's complex, and I don't know enough :-) Good luck.

A. The skin problem is most likely an alkali burn due to the high pH of concrete, about 12.5 for cured, possibly higher for the fresh mixture. Some research has been done on concrete additives such as chromates, nitrates, etc. trying to prevent corrosion of reinforcing steel. I am not aware of any commercial usage.

Rest in peace, Ken. Thank you for your hard work which the finishing world, and we at finishing.com, continue to benefit from.
A. I used to work with concrete, from pouring to finishing.
The possible cause of this skin reaction could be the latex that is usually part of certain plasticizers that are added to the mix to improve weatherability. When combined with the high pH value of concrete, this can cause lesions and burns. Try a glycolic acid based skin salve that can be obtained at most pharmacies, if it doesn't work, then you are probably seeing a latex allergy, which is very common.
Good luck!

Q. My husband has been doing concrete for the last 7 years and in the last 3 he has developed sores that develop into puss filled knots. It got so bad that one on his knee swelled to the size of 3 softballs and finally after 2 visits to the family doctor. then a 24 hour trip to the emergency room. in which they admitted him but would not lance his leg to relieve the puss. dismissed him. another trip the following day to another emergency room in which I told the doctor to lance his leg or I would leave him there. they finally did. This was before the 3 trips we made to the dermatologist in which the results came back as staph infection. The antibiotic he was given ($450.00) did not work.
It has been an ongoing thing. he has them all over his arms. legs. one on his ear. chin. etc. There has to be something they are using in the concrete that makes me wonder if eventually this will cause homeowners to have reactions since this is what homes are built with. Kind of like lead and asbestos...? I am at loss on what to do except him change his business but in the meantime other concrete workers are coming up with the same thing. Both of my children have gotten these (weird) since I sleep with him but have never gotten one. So. family doctor. dermatologist. and hospital visits have come up with nothing for a cure. I really think something should be looked into about this since I have noticed when I did research 2 years ago online there was basically nothing and now there are more people coming up with the same stuff in the concrete business. Any info or insight on this is welcomed.

A. Hi, Tracie. Concrete is extremely alkaline (almost like lye), and this would be very bad for anyone's skin. Sorry, I don't know enough about concrete in general or this specific case to have an opinion whether a chromate additive, if any, is accentuating your husband's problems with it.

Q. My husband has been working in concrete for 18 years. His exposure may not have been as great as some because he works most of the time on the curb machine. But now he has started getting odd sores on his hands. They are raised little "knots" that look sort of like blood blisters at first, then they swell up more with puss, bleed, then scab over & heal. Usually about 7 days start to finish. Most of the time, they come out of nowhere, with no previous wound or irritation. He has about 4 or 5 sores at a time, each one at a different stage of development. However this week he scratched his wrist on something and one of the sores started coming up in the middle of it. I could understand a staph infection in the case of the scratch, but I don't understand how it could just come out of nowhere to cause a sore where nothing had been before. He says he's heard from others in the business that it looks like concrete poisoning & he has a doctors appointment scheduled soon. After scouring the internet, it is frustrating to not find any medical information on these sores. But with the number of complaints & inquiries I have seen posted in different places online it's obvious that something to do with concrete work DOES cause some type of sores... It would be nice if someone could get to the bottom of this. From what I have read the doctors are not any help. I would like to ask any others who have experienced this problem to email me with their details and perhaps we can find a doctor willing to help us all. Put "Concrete Poisoning" in the subject line. Thanks!

Q. I do concrete for a living also, but am a driver that delivers it, I have started coming up with these sores, on my arms kind of look like a bug bite that has been itched and itched, I notice if I put a antibiotic on them they go away, but just come back again, They are leaving scars on my arm, I am not sure to what they are? Could any one help me also?

Q. I am a homeowner that purchased 10 yards of concrete on a weekend to pour 3 concrete walls and I suffered severe chemical burns to my wrist, both knees, stomach and inside of my legs. It should be noted that I had lined sweatpants, long sleeve shirt, gloves and boots on unlike the others working with me that had no shirts and shorts on. The doctors treated it as a chemical burn; it has been 3 months and as I expected I have several scars. I did not expect to have recurrent outbreaks of little rashes almost similar to bug bites (that itch) like someone else has previously described. I am waiting to be seen by a reputable Dermatologist but I am skeptical that he will be helpful after having read several other entries. I am also looking for any other helpful information...Thanks.

A. My husband, 55 years old, had worked in concrete and masonry most of his life until we discovered that he has concrete poisoning. He had begun developing blistering on his hands which broke and became painful sores. For several months after he stopped doing concrete work the sores continued. He tried antibiotic cream which helped heal the sores but new ones continued to appear. He tried vinegar ⇦in bulk on eBay or Amazon [affil links] to use at work. If hands dry out use hand cream.
