Re: Angle Of Friction Of Dry Portland Cement
what is the angle that dry Portland cement will slide on a steel surface ( from a horizontal axis) ?
Well, that depends on your Portland cement and your steel surface.
The best way is to measure it yourself, otherwise how will you ever be sure that some answer quoted on a discussion forum, or some figure written in a book, bears ANY relationship to your application.
if I aerated it
Aeration can be a really fun thing to do with fine powders. Some people say it can run like water. My experience is that it runs BETTER than water, and with a "viscosity" less than water ■

Angle Of Friction
So Aeration could give me the flow rate I might need and in a furry.
Do you know where I could find friction angle in a book, for proof to the big cheese?
Also looking for small aeration system and not bladder bag type( coworker wants to use them, but I think we just need a simple 3/4" pipe aeration)
thank you ■

Cement Flow From A Silo
you need a small aeration system. Air-slide fabric pads with a small blower will do. ■

Angle Of Friction Of Dry Portland Cement
Is there a mgf. of this or could a simple 1/2 air pipe work? ■

Angle of Friction of Dry Portland Cement
what is the angle that dry Portland cement will slide on a steel surface ( from a horizontal axis) ?
What is the min. angle?
If it where aerated at 6" intervals, could be min. angle?
I have a hopper 5’x8’x(34.5”From top to center of bottom auger). There is an 11” wall from top down , On the 5’ side I have an 50degree angle and 35 degree angle with open trough at bottom with 6” auger 77” long ( about a 2cu.yd hopper) . Will cement slide on the 35 degree wall.? If not, will it if I aerated it at 6” intervals placed at 1/3 height from bottom at 30psi@60 sec. apart.
Capacity is 65cuyd/hr.
I have found something saying 33 degree is min. angle, can you show publication of your answer.
OK, It occured to me that the cement will flow, but will it flow fast enough?
At a 33 dregree bin wall, how fast will it flow? ■
