Do we need a water chiller plant for RMC plant?

To maintain temperature yes you may need a water chiller plant. If concrete is needed to travel a long distance during a hot afternoon then you can use ice flakes. Ice flakes is the best way to maintain concrete temperature. These flakes should be added just before pouring the concrete into the transit mixer. The concrete temperature will be cold until the flakes are added, it will get colder when the ice melts. The transit mixer generally reaches the site during this process of melting ice. Hence the temperature of concrete is very well maintained and colder than expected at the site. After the ice has melted the water content of the concrete mix design changes hence that needs to be considered before the preparation of mix design.

Opposite end of the year has same issue, plants in some places here in UK need/use hot water feeds, as concrete mixed when it's below (IIRC) 4 deg C doesn't go well without some heating. — Preceding unsigned comment added by 94.173.237.188 (talk) 22:34, 8 April 2019 (UTC)

“The ready mixed concrete company is required” is not accurate. There are plenty of companies who do not have pumps (sort of specialty equipment), up to date equipment (look at the top picture), and certainly not “visualized production management software and also PLC controller”. Some do not even have their own plants. This is an economic deal, relating to the market they are in.

The screw graphic is cool, but shows discharge only, not charge and mix. My words are lame, a graphic guy could do better. The words match the graphic, but I suspect that drums in rhd countries may rotate the opposite direction. The mix side of the drum is normally heavier, and I think it is deliberately on the inside.

On ASTM Specs, This comment is wrong!

(After seeing the article I saw there was a lot of miss information and confusion about the main types of batch systems. ALL concrete is held to the same ASTM standards. There is ZERO difference in quality between the batch systems.) (undo) (Tag: Visual edit)

There are 2 ASTM standards regarding batch concrete. I hear all the time from uninformed engineers and building inspectors that "auger trucks" are not astm compliant. They are wrong. A quick and unconfirmed search tells me ASTM C94 is weight based "barrel" truck specifications, and ASTM C685 is the volumetric based standards. I'll try to get some time to head back and fix this if nobody else does.

RMC

Can you provide RMC history? Akshay Bacchewar (talk) 16:07, 15 December 2017 (UTC)

• The Birmingham Historical Society newsletter (link) mentions that the Sloss Ready-Mix Concrete Plant in Birmingham, Alabama, built in 1924, was the "first strictly commercial central concrete mixing plant in the world," but I'm not sure where that claim originated or to what the qualifiers refer. --Dystopos (talk) 16:27, 30 July 2019 (UTC)
