REEF SHELL IN PORTLAND CEMENT CONCRETE

THE OBJECTIVE OF THIS STUDY WAS TO DETERMINE IF REEF SHELL, WHICH OCCURS IN LARGE QUANTITIES IN THIS AREA, COULD BE SATISFACTORILY BE USED AS PORTLAND CEMENT CONCRETE AGGREGATE. PRELIMINARY TESTS PERFORMED INDICATED THAT CONCRETE MADE WITH REEF SHELL AND REGULAR SAND WAS UNWORKABLE, BUT THAT WORKABLE MIX COULD BE MADE USING 55 PERCENT CRUSHED REEF SHELL AND 45 PERCENT BEACH SAND 5 1/2 SACKS OF CEMENT AND 150 POUNDS OF FLY ASH PER CUBIC YARD OF CONCRETE. THIS CONCRETE GAVE STRENGTHS OF 3,000 PSI IN COMPRESSION, 550 PSI IN FLEXURE AND 350 PSI IN THE SPLITTING TENSILE TEST. /BPR/
