Inquiry (采购产品): extender Dear Sir, The goal is to locate an extender to mix with concrete to produce a finished product for the ornamental garden industry. The finished pieces should be able to withstand outdoor use, be lightweight, relatively strong and possibly accept colorants. The process needs to be accomplished here in the USA and must be as non toxic as possible in the production phase. Do you have a suggestion? Thank you.
