concrete formwork & concete load

[Yihan]

I have a conc wall less than 7'

the eqution for later pressue to the formwork is

P=150+9000*R/T

R-rate of conc placement
T- Temperature
is this applicable to self consolidating concrete?

 

[Ron]

Yes.

Not sure about the units of the formula, but I would have thought you would design wall formwork for "self consolidating concrete" with full hydrostatic concrete pressure.

Make a final check for simple hydrostatic load at 150 pcf.

 

[ErZaZee]

Just a thought, do you consider impact load on this one?

Because SCC is not placed in traditional lifts, and the rate of placement can be high, you should use a much higher than normal form pressure. SCC acts as a fluid, and the self-consolidating nature of the aggregates will result in near-full hydrostatic pressures. If your depth is great, consider accelerating the set (non-chloride accelerator) and placing in lifts.
