Do you know the working principle of sound insulation mortar?

In recent years, many construction projects have required sound insulation measures to reduce external interference. Building sound insulation consists of two aspects: airborne sound insulation and structural sound insulation. The sound insulation mortar mentioned in this article is a product suitable for building structural sound insulation. As we all know, sound insulation mortar is mainly composed of cement, quartz sand, sound insulation fillers, and high-quality water reducers mixed in specified proportions. It features excellent cohesiveness, outstanding noise reduction and sound insulation performance, strong adhesion to substrates, low shrinkage, and good workability—ready for use immediately after adding water. It offers stable quality, convenient construction, low consumption, and resists cracking and hollowing. During application, add an appropriate amount of water as required, mix evenly, and apply smoothly on the floor to form a sound insulation layer approximately 30mm thick.

Sound insulation mortar is applicable to all places requiring building sound insulation, including common constructions such as schools, hospitals, hotels, libraries, administrative office buildings, commercial office buildings, factories, dormitories, residential communities, villas, etc.

The function of cement in sound insulation mortar is to solidify and bond with other materials to form a stable integral structure. Adding cement to the mortar ensures the sound insulation layer forms a unified whole. Quartz sand is an industrial mineral material widely used in construction, known for its hardness, wear resistance, and stable chemical properties. Incorporating quartz sand into the mortar enhances overall solidity and earthquake resistance. Sound insulation fillers are the core component enabling the mortar's sound insulation function; when combined with other substances, they form a sound insulation layer that achieves the noise reduction effect. Water reducers are chemical compounds that improve the performance of sound insulation mortar and provide a certain degree of carbonation resistance. The above materials combine to form a flexible, integrated sound insulation system—when mixed with water during application, they solidify into a solid block after drying.

The working principle of sound insulation mortar is actually quite simple: it combines sound-absorbing materials with flexible cementitious materials, reinforcing agents, and other performance-enhancing admixtures.

The above is an explanation of the working principle of sound insulation mortar. We hope this information is helpful to you.
