Abstract: The objective of this experimental investigation is to study the strength, durability and thermal performance of ferrocement panels for its use in secondary roofing. The variables involved in the study are type of mortar mix viz. ordinary cement mortar, inhibitor admixed mortar; and mesh configuration viz. crimped steel mesh and galvanized steel mesh. Sodium nitrite based corrosion inhibitor was used in the study and added at 2% by weight of cement. The tests such as compressive strength, water absorption test, chloride ion penetration test, rapid chloride penetration test (RCPT) was conducted to assess the strength and durability of control and inhibitor admixed cement mortar. Flexural strength test, accelerated corrosion test and open circuit potential tests were conducted to assess the strength and durability performance of ferrocement panels. To find the thermal insulation efficacy, laboratory and field thermal studies were conducted on secondary roofing system with ferrocement panels. All the tests were conducted as per BIS/ASTM standards / procedures followed in premier research institutions. newline It is found that addition of inhibitor in cement mortar did not offer any negative influence on compressive strength development of cement mortar. There is a significant increase in 28 days compressive strength of the order of 22.4% and reduction in 24 hour water absorption of the order of 33.64% for inhibitor admixed mortar as compared to control cement mortar. Chloride ion penetration test and RCPT test results exhibits appreciably improved resistance against chloride penetration in normal and accelerated conditions for inhibitor admixed mortar as compared to control mortar. Addition of inhibitor in cement mortar did not offer any negative influence on flexural strength development of ferrocement panels irrespective of type of mesh and number of layers used. Ferrocement panels made with a combination of crimped and galvanized wire mesh offered improved load carrying capacity and energy absorption as compared to fer
