Description
Shirasu and slaked lime were mixed with dilute Al(H_2PO_4)_3 or PVA or Al_2(SO_4)_3 solution and press molded. The mortar bodies were prepared as follows; mixing ratio of shirasu:slaked lime=1:1, mixing water 20~30%, addition of Al(H_2PO_4)_3 or PVA or Al_2(SO_4)_3 0.25~1%, press-molding pressure 50kg/cm^2. Results are as follow; apparent density 1.84~2.28, bulk density 1.38~1.52, apparent porosity 28.6~38.7%, water absorption 18.9~27.9% and compressive strength of 28 days curing in the atomosphere 27~123kg/cm^2. The effect of PVA on the strength of shirasu mortar bodies is larger than other agents.
