Abstract:
The effect on the bond strength, as measured in a pull-out test, of strand tension and cement paste content was investigated. Several concrete mixes using a commercial lightweight aggregate with conventional sand were used in the investigation. Results showed that a decrease in prestressing force was accompanied by a slight increase in bond strength while an increase in cement content produced a slight decrease in bond strength over the range of variation of the parameters considered.
