Abstract

The use of form concrete as an alternative material in construction industries becomes popular in structure industries due to the low density range, good strength, high serviceability and lightness. Several studies have been conducted to determine mechanical properties and strength of foam concrete. However, the study of fracture energy is still ongoing and it is an important parameter of structural behavior and damage mechanism. Therefore, these studies aim to experimentally investigate the effect of span to depth (S/W) ratio on fracture energy of foam concrete using beam specimens with V-notches through the three-point bending test. Beam specimens were cased and prepared at densities 1600kg/m3. Moreover, three difference S/W ratio was used which is 4, 5 and 6 with 20 mm notch height. The beam specimens were assessed to generate the strength-displacement profiles. Fracture energy then was determined based on Hillerborg, Bazant and Comite Euro-International du Beton (CEB) models. Results show that the span to depth ratio has affected the fracture energy.
