Q: I am a structural engineer in an architectural/engineering office. A contractor has asked permission to use automotive antifreeze in mortar during cold weather, claiming it is a common practice. Our response has been to deny permission because ASTM requires "clean" water. Do you have any information on this practice? What are the effects on the masonry or mortar?
