| Description |
Experimental studies have been conducted for the bond behaviour of high performance
concrete (HPC) with fly ash as cement replacement material (CRM). Pull-out specimens as
per IS 2770 (Part-I) and IS 1786 have been used in the study. Three grades of concretes have
been designed by varying water to binder ratio and the results are compared with the
reference concrete, i.e. Ordinary Portland Cement (OPC) concrete. It is observed from the
study that for the selected quality and proportions of materials, specimens of OPC concrete
with 30 percent fly ash as CRM shown 10-15% lower bond stresses compared to the reference
concrete, however, still higher than that recommended by various codes of practices. Since,
fly ash improves the durability properties of concrete and hence increases the resistance of
the cover concrete to splitting. This can be considered as a partial substitution for the
reduction in bond strength.
