碱矿渣泡沫混凝土的吸声性能试验研究
Experimental Study on Sound Absorption Performance of Alkali Activated Slag Cement Foam Concrete
摘要
Abstract
In order to develop a new type of green and low carbon absorption material, alkali activated slag cement foam concrete was prepared based on chemical foaming.The effect of density, content of alkali and content of fiber on the compressive strength, water absorption and sound absorption characteristic were analyzed through testing.The results show that with the increase of density, the compressive strength of the material increases, the water absorption decreases, the sound absorption performance of the low frequency increases, and the sound absorption performance of high frequency decreases.With the increase of alkali equivalent, the compressive strength is improved, the absorption coefficient is increased after the first reduction, and the absorption coefficient within the range of 50 Hz and 1600 Hz is enhanced.The suitable dosage of fiber can improve the compressive strength of materials, but the excessive content of fiber is detrimental to the development of strength.Moreover, the incorporation of fiber may improve the sound absorption of materials in high frequencies.关键词
