How much time for Concrete Truck

**herbieinla** · 03-26-2009, 02:56 PM

Can anyone help me....? I pour concrete from a concrete truck......On the truck ticket it states what the time is when the truck is loaded with concrete. Different types of concrete must be completely poured in a certain amount of time. I am trying to make a spreadsheet where i put in the time of batching, and it will tell me what time it will be when it's time is up. Any help will be appreciated...thanks Herbie

Create a chart that lists concrete types in one column and the Pour-By-Time in the next column.

Then mockup your list entry chart where you'll enter the mix times and concrete type. Post that up and we'll offer you a formula to automatically give you a cut-off time.

What are the different types of mixes, and what are their allowable rest times before pouring?

There is class A concrete = 90 minutes it has to be all poured
class AA concrete = 90 minutes
Minor Structure conc. = 60 minutes
Type B concrete = 45 minutes
there are admixtures to concrete that may retard setting times or shortening that time... different contracts may call for different specs...
There are probably 15 or so types of concrete that we use but most have a rejection time of 90 minutes....
