Abstract：Artificial sand within 3 mm particle size and continuous grading is obtained by crushing and screening the sponta-neous combustion gangue,using the sand to confect the mortar with different additives and admixtures,testing its workability,appar-ent density and different age strength by experiment. Selecting an optimal mix proportion to make wall specimen considering vari-ous performances and carry out test with its heat conduction performance and sound insulation performance. The experimental re-sults show that the feasibility of the artificial spontaneous combustion gangue mortar as the material of light wallboard with enough strength for the prefabricated steel building system was approved,and,the property index of heat conduction and sound insulation can meet the basic requirement.
