摘要
以微孔吸声结构原理为主要设计依据,研究了发泡剂A的掺加工艺,发泡时的养护温度对水泥基多孔混凝土中泡沫胶结料吸声性能的影响,及其掺量对水泥基多孔混凝土吸声性能的影响。结果表明发泡剂A的加入能显著提高水泥基多孔混凝土的吸声性能。
Based on the porous structure, cement porous sound absorption concrete was designed.We investigated the acoustic properties with the factors such as technical and quantity of vesicant, curing temperature.The results show that vesicant could improve the sound absorption properties of cement base concrete promptly.
