Low-Frequency Sound Proof Cement-Based Syntactic Foam

Norwanis Hasan, Syed Fuad Saiyid Hashim, and Zulkifli Mohamad Ariff
Abstract—A low frequency soundproofing cement based material has been developed in this study. This closed-cell composite material basically consists of a cement matrix embedded with in-house developed Cement Spheres (SC) and Cement Hollow Sphere (CHS) or macrospheres. The produced foams known as Cement Syntactic Foam (CSF) were characterized for its’ properties including stress-strain behaviour. Acoustic Transmission Loss (TL) test was conducted on two types of CSF, namely CSF-CS and CSF-CHS and the results were compared to plain cement (PC). It was observed that the CSF showed a good mechanical properties and better sound TL in a low frequency range. The significant improvement in the TL was shown by CSF with incorporating CHS. However, no significant increase in the TL was observed with the increasing sample thickness. Overall, it was discovered the produced CSF has potential in the application of lightweight soundproofing material substituting common barrier material.

Index Terms—Soundproofing cement based material, closed-cell composite, cement syntactic foam, transmission loss.
