| Summary: | 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. |
