Sound insulation mortar structure

Abstract

A sound-insulating mortar structure comprises: a substrate and a plurality of noise-reducing particles. The substrate is formed by mixing cement and sand in a certain proportion and has a plurality of pores inside. The plurality of noise-reducing particles are uniformly filled in the pores of the substrate. By means of the micropores of the noise-reducing particles, after mixing with a liquid medium to form a sound-insulating mortar, it can effectively block or absorb sound energy and also has a lightweight effect. Accordingly, the sound-insulating mortar structure of this invention utilizes the integrated combination of cement mortar and noise-reducing particles, and can be applied to floor tile laying and wet lightweight partition construction, while solving the problem of poor adhesion of heterogeneous materials and improving living comfort.
