Abstract

Foamed concrete as favorable substitution conventional concrete can be used in wide range of constructions. Usage the Polypropylene Fibre (denoted as PF) in this investigation examined contribution of PF on strength of foamed concrete. Mechanical test were performed to measure effect of PF on improving compressive and splitting tensile strength. Results indicate that PF significantly improving compressive and splitting tensile strength. Behavior of PF where drawn into foamed concrete similarly with normal concrete. The fibrillation and interfacial bonding between PF and matrix has been occurred and reduced the micro crack of matrix and prevented propagation crack growth. However influence of porous of foamed concrete is considered. Process of curing continuation 60 and 90 days indicate that interfacial adhesion is wider when cement hydration process is running. Scanning Electron Microscope (SEM) exhibits condition microstructure of foamed concrete added by PF alter the microstructure, especially interfacial bonding between PF and matrix.
