Study On The Performance Of The Ground Floor Noise Insulation Mortar

Under the conditions of rapid economic development,Energy issues highlighted as an important factor restricting the development, Therefore building energy efficiency has become a worldwide trend. But urbanized and living standard's enhancement also causes the noise pollution to propose the daily agenda. Meanwhile, housing floor residential solid percussive acoustic isolation and poor performance caused a lot of disputes. Impact Sound Insulation between the floors become a major issue addressed as a matter of urgency. Based on the basis of EPS insulation mortar, a research and development of both insulation and acoustic properties of the ground floor, acoustic insulation mortar.Based on the assurances EPS insulation mortar work on the basis of performance, Select floating beads, used tire rubber powder several acoustic insulation materials were incorporation to the mortar, Inspection of its EPS insulation properties of mortar. EPS were different and different size particles of waste rubber powder comparison test. Choose the best content of all types of materials to comprehensive mortar preparation, testing their performance and practical application mortar comparison.This paper identified the basic mortar acoustic insulation formula. Study of floating beads and tire rubber powder insulation properties of mortar. The results showed that the mortar physical and mechanical properties are somewhat lower, but the acoustic properties of mortar larger upgrade; Light-weight use of renewable EPS particles when mortar cost-effective; Different size of the mortar used rubber powder performance of smaller, the greater thickness of mortar, hit acoustic performance, the better. Mortar renewable EPS insulation to add floating beads and tire rubber powder, Prepared to have good performance of the ground floor, acoustic insulation mortar, compressive strength of 0.33 MPa, pressure-shear bond strength of 0.19 MPa, linear shrinkage rate of 0.25%, 4.88% volume of water absorption, thermal conductivity of 0.069 W / m ? K, percussive acoustic noise-evaluation of the Single-value of 65.0 dB. Its comprehensive performance and application of a research and analysis.
