Today, municipal solid waste (MSW), noise pollution and fire attack are three ongoing issues for inhabitants of urban including in Malaysia. To solve these issues, an eco-friendly autoclaved aerated concrete (AAC) containing recycled ceramic and gypsum waste (CGW) as partial replacement for sand with different ratios (0%, 5%, 10%, 15%, 20% and 25% wt) havebeen prepared. Thework density (w) andmechanical properties of samples such as compressive strength (fc) and specific strength (S) havebeen investigated. The functional properties of samples such as sound absorption coefficient(SAC)and direct fire resistance also havebeen carried out. All samples showed normal colorbehaviori.e. grey and free crackwith a wwasin the range of 593.71 kg/m3to 605.29 kg/m3. The fcincreased in the range of 6.10% to 29.88%. The maximum value of fcwas 2.13MPa for 15% wt of CGW. The SAC of samples at low frequency (500Hz) ishigher than reference sample (RS).All AAC-CCW samples are categorized as material class Band Cabsorbers at frequency 500 Hz. Except for RS, the fire resistance results showed the physical surface of the samples had free crack and not burned during direct fire at 950C for 300s. The results showed that CGW havepositive effect on the mechanical and functional properties of AAC.
