I was always learned it can not, but today we took the chance and proved it can.

What did you do flood it with water, you must like cleaning hose.

What was the %, was it 1 1/4 - ? That's impressive it either will or won't! Seems to be the design at the end.

It was 50% big rock and 50% pea gravel and very high in the cement 5 inch slump, and as bonnus somme fly as. c28/35 xf4 Whe did a parking dek with pea gravel. and for a inclined plane there was an other mix. so whe had the choice, chaince hose or give it a try.

i done that before trick is dont drown it with water pump it tight about 4 inch slump worked for me

50 50 1 1/4 and sand, wow!

Everybodys stone pile is different.  I've had 1 1/4 mix that is so stoney the S tube won't move.

Hey Superdoffer you would only use river pebble where you are not crushed aggregate isnt it ?

mainly river peble, some crushed rocks for the finnes. but whe have also mixes whit a pers. reciceld concrete. 

Haha. I could have told you it would work. Here in Norway we always use 3'' for the big rock. But 25% redused rock amount. For the nutgravel we use 2,5'' hoses. The hoes man can just keep the end in his hands. And for filling cracks we have 2''. But than you need concrete without rock. Last week I had some 4'' hoses again because we had a mix that couldn't be redused. It was a bridge. But MY GOD those 4'' are heavy!!! I can't understand how we managed!!! Good luck ;-)

Hey dipstick 4"hose isn't havy if you know howe to handel it. I think  you mis the men in red, and the G boys. L.O.L. They are the only one's who can handel 60 cubic meter an hour whitout soaking it whit water.
