| 摘 要： | 文章对橡胶水泥砂浆的吸声性能进行了研究。结果表明：橡胶的粒度和掺量、砂浆的水灰比、试样的养护方式等因素都对其吸声性能产生了影响。加入橡胶后水泥砂浆的导声系数会减少,其中以混合胶粉的改性效果最好,其导声系数较其他三种粒度的胶粉砂浆为最低,随着橡胶掺量的增加,其吸声效果也在增强,吸声系数越来越低,但当掺量值达到40%时,导热系数值为最少,砂浆的水灰比不同其隔热效果也有很大区别,水灰比为0.5时吸声系数最低。

| Abstract: | The paper researches on acoustic absorption of rubber modification cement mortar.The results show：the rubber particle size and content,mortar to cement ratio,sample conservation and other factors have an impact on theacoustic absorption performance.Mediated acoustic coefficient of cement mortar reduces after adding rubber,in which the modification of mixed rubber powder has the best effect.Compared with other three types of rubber mortar,the mediated acoustic coefficient of the mixed rubber is the lowest,with the enhancement of rubber,the acoustic absorption increases and acoustic absorption coefficient becomes lower and lower.When the doped value reaches 40%,thermal conductivity coefficient is the lowest.Different mortar cement ratio has different insulation effect,acoustic absorption coefficient is thelowest when water cement ratio is 0.5. |
