The research and practice on strengthening of RC & brick wall structure with ferro-cement laminates in the home and abroad are discussed. It is developed for the mechanism and behaviour of RC flexural members strengthened with the ferro-cement. The main problems of strengthening buildings with the ferro-cement,which should be solved in the future, are presented for strengthening engineering.
