EFFECT OF POZZOLANS ADDED TO SAND-GRAVEL CONCRETE PAVEMENT

A MAJOR PART OF KANSAS HAS NO LOCAL SOURCES OF COARSE AGGREGATE FOR CONCRETE. SILICIOUS AND GRANITIC SANDS AND GRAVELS FROM STREAMS OR DRY PITS ARE USED EXTENSIVELY FOR CONCRETE IN THESE AREAS. MANY OF THESE SAND GRAVELS ARE REACTIVE WITH CEMENT AND SUBJECT TO ABNORMAL EXPANSION IN CONCRETE. IN 1949 A SIX MILE EXPERIMENTAL PAVEMENT PROJECT WAS COMPLETED TO EXPLORE THE POSSIBILITIES OF INHIBITING THIS TYPE OF EXPANSION BY ADDITIONS OF VARIOUS POZZOLANS. SECTION WERE CONSTRUCTED USING THESE POZZOLANS AS A REPLACEMENT FOR EQUAL AMOUNTS OF PORTLAND CEMENT AND, AS A BASIS FOR COMPARISON, SECTIONS WITH NO ADDITIONS, AND SECTIONS TO WHICH ADDITIONS OF CRUSHED LIMESTONE WERE MADE. ALL OF THESE TYPES OF CONCRETE WERE CONSTRUCTED IN SECTIONS WITH AND WITHOUT AIR-ENTRAINMENT, AND WITH FIVE BRANDS OF CEMENT WIDELY USED IN THIS AREA. THIS PAPER IS A SUMMARY OF THE OBSERVATIONS MADE, AND DATA ACCUMULATED, DURING THE FIVE YEARS WHICH HAVE ELAPSED SINCE THE CONSTRUCTION OF THIS PROJECT. /AUTHOR/
