I would glue it back together with akepox it made by akemi but is epoxy resin rather than polyester resin to clean it I would sand blast it with soda crystals they are soft enough to clean it with out being harshly abrasive like sand blasting , you could try then resurfacing it with portland stone mix itsca little outside my area of knowledge but its how stone facades are cleaned and resurfaced , it you speak to Gary Bass at Apex grange he would be able to tell you what you need and has all the products needed to do it
