Sound absorption characteristics of ternary concrete using SCBA and silica fume as partial replacement of cement in concrete

Abstract

The ambient noise from transportation and in metro politan areas due to tremendous inhabiting density, it promotes infelicitous noise threats, which originates severe health problems to humans and other living organisms. The present study focus on the employment of industrial and agricultural misuse can be adopted in concrete as partly replacement of cement to reduce the cost, also improves the concrete properties and reduce environmental pollution. The main objective is to assess sound absorption of TBASF concrete by partly replace with cement with SCBA (0%, 5%, 10%, 15%, 20%, and 25%) and additionally 10% Silica Fume. Compressive strength, Split tensile strength, Flexural strength tests were conducted for 7days, 28days, and 56days and sound absorption test was conducted for 7days and 28days. The optimum strength obtained for the mix TBASF15 at all the ages. Further, the results of the sound absorption coefficient (α) of SCBA Silica Fume concrete compared with the sound absorption coefficient (SAC) (α) of parent concrete is carried out by using the impedance tube.
