In order to recycle industrial waste fly ash and reduce the production cost of cement
based foam insulation board，with ordinary PO 42.5 Portland cement as the main gel material，
add 8% sulfur aluminate cement as procoagulant，plus 7% hydrogen peroxide as foaming agent，
water ash ratio of 0.5，with fly cement instead of Portland cement（replacement of 0，10%，
20%，30%，30%，40%）prepared cement based foam insulation board. The influence of fly
ash incorporation on the physical，mechanical and thermal properties of foam insulation plate is
studied. The results show that when the fly ash incorporation is 20%，the foam insulation board is
the best comprehensive performance，and can also improve the durability of the material.
