Padstone / lintels

Can anyone tell me is it OK to use concrete lintels as padstones to rest a I section UB on? Just seems lot simpler!
If it makes a difference, beam is about 8'x 7"x4". Padstones supposed to be 8"(l)x4"(w)x6"(d).
If OK, what mix should I uses to set them on? Does the beam sit on a mortar mix or just rest on the pads?

Or can I pour them myself within shuttering on the ground a few days prior and then lift them in place? What mix would this be? Any reinforcing necessary?

irose, both your suggestions are common practice.

for beams that sit on a 4" wall at 90deg we always use pcc lintels. usually 2 or 3 courses deep and a projection of 100mm either side of the beam.

and for beams that sit in line on cavity walls we pre cast a concrete block with shutter boards, usually in the corner of an un- finished room.
e.g size: 275x150x250mm.

4-1 mortar will suffice most scenarios.
Thanks for that.

What mix would you recommend for the "on-site" block? Does it need reinforcing or maybe chicken wire?

a standard mix of 6 ballast to 1 cement will do.

don't let the block dry out too quick.

use polythene around the edges of the shutter to keep the moisture in and to stop it sticking to the shutter boards.

if you can let it cure for a week

yes chicken wire would be a good binder.
