Portable Concrete Mixers How To Buy[edit]

hello can any one tell me how many times or at what speed drum of mixer should rotate ones it leave the batching plant till it reaches the site?


Hello,

Can anyone tell me what to look for when buying a cement / concrete mixer? I need to do a good amount of work around my home and they are som good size projects. I found this link:

   [1]


But there ar just so many cement mixers to pick from. Which brands are good / sizes?????


I bought the Imer version and it takes about 2-3 60 lb bags at a time. Anything less becomes a bit tedious.

What does a MacGyver episode where he builds a plane have to do with concrete mixers? Just because the motor came off of one? If someone used a bolt from one, would that qualify too? How does that add anything to this article? 173.72.230.166 (talk) 14:59, 9 August 2009 (UTC)

'Ready Mixed' concrete[edit]

This is capitalized. If it's a product name, the generic name should be indicated. Wakablogger2 (talk) 06:17, 4 July 2010 (UTC)

Name for trucks[edit]

I came to this article looking for the name of the trucks that carry concrete/cement. From Googling, it appears they are called a number of things including "concrete mixers," "mixer trucks," "truck mixers" and "concrete trucks." Wakablogger2 (talk) 06:19, 4 July 2010 (UTC)

A pragmatic issue[edit]

What happens when a concrete mixer truck gets stuck in traffic for too long? 87.113.1.169 (talk) 15:42, 25 March 2013 (UTC)

You "lose the load". Additional water may help, but will weaken the final product. In extreme cases 10 or 20 pounds of sugar will delay setting drastically, but again, you lose the load. Worse case, the load sets in the drum, and a couple of laborers go in with air hammers to "chip" it out. Chipping is also done periodically as maintenance, it's very hard to keep the back of the fins clean.Sammy D III (talk) 21:31, 3 June 2013 (UTC)

dynamite[edit]

Has anyone here ever heard of an actual case of dynamite being used to break up concrete in a drum? Has anyone ever read of this in any reliable source? Any Rupert Murdock tabloid? Does this even sound plausible?

In over fifteen years as a ready-mix driver in the U.S., talking with other professionals, quality control engineers, reading trade journals, and listening to "old boy" stories, I have never heard of any thought of anything even similar to this.

I have driven Challenge-Cook Brothers, Rex, and McNelius Truck Manufacturing 10 yard mixers on FWD, Oshkosh, and Mack trucks. In the worst cases, it has never taken more than two working (8 hour) days to "chip a drum" using two men (safety reasons) with pavement breakers (a.k.a. jackhammers). The very idea of using dynamite inside a steel drum sounds obscene.

I am going to wait a short time, then delete this almost certainly complete crap.Sammy D III (talk) 09:15, 4 October 2013 (UTC)

Volumetric mixers[edit]

The picture of a Volumetric Concrete Mixer is of an interesting vehicle. Manufacturer’s site here: [2] It does not mix in transit, it arrives on the site with the materials separate. They are mixed in an auger tube on the rear of the truck. It can mix small amounts on demand, and can be reloaded on the site. Sort of a super hero version of a mixer trailer.Sammy D III (talk) 23:55, 12 January 2014 (UTC)

Laboratory concrete mixers[edit]

Concrete mixers used in laboratories for testing concrete, cement & mortar should be added into this article as well. I would start the section; anyone with expertise in this area could help in expanding.Zamy85 (talk) 15:13, 16 September 2014 (UTC)

I don’t know what you have, very general thoughts.
How much are you making, how many meters or yards? Are you using a screw or dump type drum? Either way, you would want the drum completely clean, no buildup.
You measure dry material by weight, water and liquid admixtures by volume (liters or gallons/ounces). I would think you would want to measure both very carefully?.
In the field you measure slump by mixing X (sometimes 60) revolutions, then discharging more than is needed. You also take the temperature. That is very crude, a test would me much closer?
To make a test cylinder you use a round plastic or cardboard tube with a closed end, like a water glass but the sides don’t taper. When the concrete sets enough, you take the plastic off, leaving a short shaft of concrete. You compress it until it breaks to test strength. You break one at 2 hours, 12 hours, and 24 hours, something like that?
You could make the drum mixing speed exactly what you want? By measuring hydraulic pressure to the mixing motor you can tell slump, sort of. How much pressure does it take to turn the drum?
Is it on wheels or stationary? When you mix, the truck rocks all over the place. You could eliminate that with a solid mounting? On the other hand, if it was on wheels, the rocking should be about the same on all tests?
If it helps you any. Sammy D III (talk) 15:08, 17 September 2014 (UTC)

Added Concrete mixer animated GIF[edit]

I added a GIF animation in the "Concrete mixing transport trucks" section to explain the mixing and discharging processes and the operation of Archimede's screw inside the drum.

Use in Fiction Concrete Mixing Machine[edit]

The Gloppitta-Gloppitta machine features prominently in the 1965 film "How To Murder Your Wife" starring Terry Thomas.

There is a 33 second video on YouTube of the famous setup of the scene: https://www.youtube.com/watch?v=KhXb04Ho0-M

There is a Wikipedia article on the film.:https://en.wikipedia.org/wiki/How_to_Murder_Your_Wife

Pull Quote: Feeling a need to vent his frustrations, Stanley concocts a plot in his comic strip to kill Brannigan's wife by drugging her with "goofballs" and burying her in "the goop from the gloppitta-gloppitta machine" at a construction site next to their home, so that Brannigan can then resume his career as a secret agent. As always, he enacts the events before drawing the strip, but after drugging his wife during a wild cocktail party, he carries her up to bed, then uses a department-store mannequin for the burial.

I would love to insert this myself but I don't know if self referencing (Wikipedia to Wikipedia) is allowed. I was unable to determine any one person as major contributor to help with this entry so I'll let it float here on the talk page assuming someone will see it someday MisterHOP (talk) 00:14, 10 May 2016 (UTC)


Nominate for deletion/update[edit]

Hello, this photograph seems to be advertorial, perhaps it would be better to edit the photograph to remove branding? AjaxFiori (talk) 07:20, 13 August 2016 (UTC)
