Inquiry (采购产品): Foaming agent for grout We are looking for a foaming admixture to make foamed concrete backfill with a strength of about 2000 psi fro a mine excavation. Do you have a product that when added to a lean cement/sand /water grout creates a low density high volume fill. If so please provide info and a quote. **** Hidden Message ***** Chris Gill OH 44113 USA Company: Cargill Deicing Technology E-mail: chris_gill@cargill.com **** Hidden Message ***** chris_gill@cargill.com
