Effect of Single Fiber Pull Out Test Result on Flexural Performance of ECC

Abstract

Rathod JD

Study of effect of single fiber pull out test result on flexural performance of Engineered Cementitious Composite (ECC) is carried out in the present work. Cement: sand ratios of 1:0.5, 1:1, 1:1.5, and 1:2 are used in composition of ECC. Beams of 20 and 30 mm depth are tested under displacement control and four point loading arrangement. First crack strength, ultimate strength, toughness index, deflection hardening and reserved flexural strength are evaluated. Single fiber pull out test of 6 mm embedded length is carried out to evaluate frictional bond strength. An equation is suggested to evaluate ultimate flexural strength of ECC considering effect of micromechanical parameters in general and frictional bond strength in particular.
