SPECIAL ASPECTS OF THE USE OF FLY-ASH FROM CEMENT PLANTS AS FILLER FOR ASPHALTIC CONCRETE /IN RUSSIAN/

THE RESEARCH CARRIED OUT OVER THE LAST FEW YEARS IN THE USSR ON THE POSSIBLE USE OF FLY-ASH AS A FILLER FOR CONCRETE IS DESCRIBED. THE MAIN CHARACTERISTICS OF FLY-ASH ARE ITS CHEMICAL ACTIVITY AND TENDENCY TO CEMENTATION; A DIRECT RELATION EXISTS BETWEEN THESE TWO PROPERTIES. THE CEMENTATION OF FLY-ASH IS CAUSED BY THE PRESENCE OF FINELY DISPERSED PARTICLES AND SURFACE-ACTIVE MINERALS. CEMENTATION PROCESS IN FLY-ASH IS INEVITABLE AND RESULTS FROM A DECREASE IN DESNITY AND HOMOGENEITY OF THE ASPHALTIC CONCRETE STRUCTURE. THE PRESENCE OF ACTIVE COMPOUNDS IS RELATED TO THE DECREASE IN PLASTICITY OF THE ASPHALTIC CONCRETE. STABILIZATION METHODS ARE PROPOSED. PRELIMINARY TREATMENT OF FLY-ASH IN THE GAS PHASE ELIMINATES ALL PROBLEMS ASSOCIATED WITH ITS UTILIZATION IN ASPHALTIC CONCRETE. THE QUALITY OF ASPHALTIC CONCRETE CONTAINING TREATED FLY-ASH IS THE SAME AS THAT OF ASPHALTIC CONCRETE FLY-ASH IS QUOTED. /LCPC(A) /RRL/
