Acoustic Performance of CBA Concrete SpringerLink

Based on the acoustic tests conducted, the sound absorption coefficient of CBA concrete is higher than that of normal concrete. From the impedance tube test, the highest noise reduction coefficient recorded was 0.35 when 100% of CBA was used to replace fine aggregate. Meanwhile, normal concrete has a noise reduction coefficient of 0.20.

Improved performance of coal bottom ash co

The present research aims to prepare concrete by adopting coal bottom ash (CBA) as a replacement of fine aggregate. Various strength and durability tests were performed by replacing fine aggregate with CBA in percentages varying from 0-80%. To achieve workability requirement in specimens with higher CBA content, higher water to cement ratio was adopted, which lead to variation in the water
