concrete formwork & concete load

concrete formwork & concete load

concrete formwork & concete load

(OP)
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?

RE: concrete formwork & concete load

Yes.

RE: concrete formwork & concete load

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.

RE: concrete formwork & concete load

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

RE: concrete formwork & concete load

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

RE: concrete formwork & concete load

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.
