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.}, pages = {37--40}, title = {シラスの工業的利用に関する研究 (第6報) : ポリピニールアルコール, 硫酸アルミニウムおよび重リン酸アルミニウムを添加した水硬性石灰モルタル}, volume = {9}, year = {1968} }
