PROPERTIES OF COMPACTED SEWAGE ASH
PROPERLY COMPACTED SEWAGE ASH FROM A LOCAL TREATMENT PLANT EXHIBITS SUFFICIENT STRENGTH AND STABILITY TO RECOMMEND ITS USE ON A TRIAL BASIS AS A BACKFILL, LIGHTWEIGHT STRUCTURAL FILL, OR SUBBASE MATERIAL. LIME IS ADDED DURING SEWAGE TREATMENT, AND SUBSEQUENTLY IS CONCENTRATED IN THE ASH RESIDUE AS A RESULT OF INCINERATION. THE HIGH LIME CONTENT OF THE ASH IS LARGELY RESPONSIBLE FOR ITS AGE-HARDENING PROPERTIES AND RESISTANCE TO MOISTURE AND FROST. THE COMPACTION CHARACTERISTICS OF SEWAGE ASH ARE SIMILAR TO THOSE OF A CONVENTIONAL SOIL, EXCEPT THAT MAXIMUM DRY DENSITIES ARE LOWER AND OPTIMUM WATER CONTENTS ABOUT DOUBLE. USE OF COMPACTED SEWAGE ASH IN CIVIL ENGINEERING PRACTICE WOULD SERVE A TWO-FOLD PURPOSE,VIZ., WASTE DISPOSAL ON THE ONE HAND, AND PROVISION OF A LIGHTWEIGHT FILL OR EMBANKMENT MATERIAL. /AUTHOR/
