Has anyone had any experience with a 4000 LW w / novamesh 850 mix?

Is it pumpable?  How hard is it on the equipment?  Preferred slump at the pump?

Thanks

liteweight I would suggest no less than a 6 1/2 or 7 at the pump, just depending how much line you have off the end.

You have to make sure they soak the lightweight and it's gotta be wet and it will pump like butter.

It's like learning to pump concrete all over again.Now you have rocks in the mix that suck up water.In ideal conditions the liteweight is soaked in ponds,left in mixer barrels over nite in water,sprinklers on a pile ,never liked that one.If it's not pre soaked, your pump will tell you right off.I would start off with a good 7in slump till you get it out the end of the hose.Hope you got a 1/2 yd of grout to start.It helps.Whatch your pressure gauge priming.The crew on the end of the hose will let you know if it's wet enought.And on liteweight they should take samples at the end of the hose And pray for rain the day before,it pumps great

does the supplier have any experience with lightweight?

When the mud gets there, grab a handful of the rocks out of the mix, throw it in a pail of water, if they float, have them sign your ticket, pack up and go home, it ain't worth the heartache.

Are you talking steel fiber & lite weight?? Or the nylon stuff?

thanks for the replies.  Not worried so much about the LW as much as the nova meash.  It is a combination steel fiber / polypropylene fiber.  has anyone pumped nova mesh? 24lbs

Thanks

I have pumped it b-4, and I think it was nova mesh. Call the Nova rep about the 24 lbs, I cant remember the amount. Do float the lite wght!

Good Stuff,,,,  pumped it thru 100' of 4" line,,,,   With lightweight,, always start wet, then back off on the water on the 2nd or 3rd truck,,,   Always prime with grout when pumping lightweight if you have system layed out
