Quality control of grout for post tensioning structure

The scope of segmental post tensioning construction in India is increasing rapidly in India. Grouting of sheathing duct is a very important activity to protect strand from corrosion. The life span of segmental post tensioning structure depends on the quality control of grout. Several studies reported that failure of post tensioning structure was due to corrosion of grout. This happened due to the presence of voids in the air in the grouting duct. The presence of voids occurred due to bad quality control of grout. Very limited tests are recommended to Indian Roads Congress (IRC) specifications. IRC practice is to be improved to avoid failure of post tensioning structure. Quality control tests of grout are recommended for improving quality control of present IRC practices, including air void destruction tests.
