Shirasu is distributed chiefly in south Kyushu and consists of volcanic ash, pumice and other materials. Shirasu, slaked lime and fly ash were used as raw materials of the porous lightweight autoclaved bodies. The porous lightweight autoclaved bodies were prepared as follow; mixing ratio of shirasu:slaked lime:fly ash =0.7~1.5:1:0~0.5, mixing water(added small amount of NaOH, Al(H_2PO_4)_3 etc.) 65%. Al powder 0.15~0.20%, curing pressure 10kg/cm^2 curing time 8hrs. Results are as follow; bulk density 0.60~0.72, water absorption 48~95%, compressive strength 3.2~22.7kg/cm^2, bending strength 1.5~10.4kg/cm^2.
