SHELL CONCRETE PAVEMENT

THIS REPORT DESCRIBES THE TESTING PERFORMED WITH REEF SHELL, CLAM SHELL AND A COMBINATION OF REEF AND CLAM SHELL USED AS COARSE AGGREGATE TO DETERMINE IF A LOW MODULUS CONCRETE COULD BE DEVELOPED FOR USE AS A BASE MATERIAL AS AN ALTERNATE TO THE PRESENTLY USED CEMENT STABILIZED BASES. THE TESTS INCLUDED, COMPRESSIVE, FLEXURAL AND TENSILE STRENGTH, DRYING SHRINKAGE, BOND TO REINFORCING STEEL, FREEZE AND THAW DURABILITY AND DYNAMIC MODULUS OF ELASTICITY . A TOTAL OF TWENTY CONCRETE MIXES WERE EVALUATED, INCLUDING TWO GRAVEL AND SAND MIXES FOR REFERENCE PURPOSES. CEMENT CONTENTS OF THE MIXES WERE 4.0, 5.0 AND 6.0 SACKS PER CUBIC YARD FOR EACH VARIABLE TESTED. THE RESULTS INDICATED THAT A 4.0 SACK MIX USING REEF SHELL AS THE COARSE AGGREGATE PRODUCED THE LOWEST MODULUS OF ELASTICITY. /AUTHOR/
