| Abstract: | The effect of rice straw volume content on the performance of magnesium oxysulfide foam lightweight insulation materials was studied.The dry shrinkage,water absorption,thermal conductivity,compressive strength and flexural strength of the magnesium oxysulfide foam lightweight insulation materials mixed with rice straw were tested,and the microscopic pore structure test was carried out.The results show that with the increase of rice straw volume content,the dry shrinkage,water absorption,thermal conductivity and compressive strength of the magnesium oxysulfide foam lightweight insulation materials gradually decrease,but the flexural strength increases within a certain range.The reasonable volume content of rice straw is 15%~45%. |
