I've been told that there are chemical agents that will stop the curing of concrete. I'm also told that adding sugar will stop it/slow. There are defiantly chemical additives (Used in summer heat) that slow it way down.

Stuff happens - when they get back I assume they [pay someone to chip it out. They can buy a lot of help at min wage before paying for a new mixing drum. This was the same site that had an existing refinery next door. The Pres or VP of Tesaco was coming for a visit so they repainted the logo on one of the large holding tanks - they were usually a few hundred feet across 30 feet tall and had a floating roof. Someone forgot to check the valved air pipe - to allow air into the tank as whatever ws stored inside was pumped out. Without the air vent open a vacuum was created and sucked the side of the tank in - right across the logo. Naturally ;-) That facility also had a major explosion & fire during a maintanence outage. Parts of the operating plant were inoperative so repairs could be made. Unfortunately, while welding there was a hydrogen leak nearby and a huge explosion occurred. 5 or 6 died and a dozen + were badly burned. Those with severe injuries were med-flighted to a burn hospital in Houston. Houston has some of the best hospitals in the country. That was in the mid 70s. I was in a trailer adjacent to the plant which exploded - seperated by several retaining ponds - felt like a minor earhquake!

Only if they're delivering or if he didn't have a good place to clean out before returning. I spent a whole summer working on the Casco Bay Bridge. http://en.wikipedia.org/wiki/Casco_Bay_Bridge We sent away many a truck with its drum turning because when we were pouring we'd have ALL the available trucks in the greater Portland area, they'd dump, and turn and burn back ot the plant for another road. Running out of concrete was NOT an option. I actually got dispatched to an accident scene one time to explain to the Portland PD how important it was for traffic to get restarted because we'd have to rip out 200 linear feet (4 lanes wide!) of concrete if the trucks couldn't get through before what we'd already poured hardened. I got permission for the trucks to go the wrong way down a one way street as a detour around the accident scene. BTW I was dispatched because I was one of the few workers who didn't have a DWI and could get on the company's insurance. Anyway at the end of the pour (usually 300-350 linear feet) the trucks would have time to get good and clean (we had running water there) so they'd go back without the drum turning... -Curt Date: Tue, 4 Aug 2009 17:18:28 +0000 (UTC) From: pm7...@comcast.net Subject: [MBZ] O/T Concrete Mixer Trivia To: Mercedes Discussion List <mercedes@okiebenz.com> Message-ID: <31941905.6499651249406308848.javamail.r...@sz0127a.westchester.pa.mail.comcast.net> Content-Type: text/plain; charset="utf-8" Ever notice that whenever you see a mixer moving the drum is turning?
