Abstract：Glutinous rice glue-plant straw-soil-fly ash brick(GPSF brick)was prepared by using plant straw,ramie fiber,soil,fly ash,glutinous rice glue as raw materials,and the influence of NaOH concentration,soaking straw time,glutinous rice glue dosage ratio,curing days,soil and fly ash mixing ratio on the mechanical properties of GPSF brick was studied by orthogonal experiments.The results show that the ratio of fly ash has a significant impact on the compressive strength of GPSF bricks.The concentration of NaOH,soil content,and fly ash content have a significant impact on the flexural strength of GPSF bricks.The optimal mix ratio for GPSF bricks is:NaOH concentration of 7%,straw soaking time of 36 hours,curing time of 21 days,glutinous rice glue,soil,and fly ash content of 100%,125%,and 50%of plant straw mass,respectively.The compressive and flexural strength of the prepared GPSF bricks are 10.03 and 6.67 MPa,respectively.
