Abstract

It is carried out a quality assessment on lightweight aggregate of the stacked self combustion coal gangue in GaodeMine of Fuxin in Liaoning according to the national standards. On the basis of satisfying the demands of national criterion of lightweight aggregate through all kinds of indexes, taking the crushed self combustion coal gangue as coarse aggregate, polypropylene fiber as reinforced materials, ten sets of self combustion coal gangue concrete specimens are designed by uniform test, and lots of tests of compressive strength, splitting strength and flexural strength are also carried out. The research results show that because self combustion coal gangue coarse aggregate in Gaode Mine of Fux in matches with the strength and Yang's modulus of a matrix, and itself strength is less than natural macadam, but it sufficiently displays coordination effect between aggregate and matrix, which can produce C40 concrete with excellent property whose early stage strength develops more perfectly.
