REEF SHELL IN PORTLAND CEMENT CONCRETE AND REEF SHELL-BEACH SAND CONCRETE

THIS PUBLICATION CONTAINS TWO REPORTS CONCERNED WITH THE USE OF REEF SHELL AS A COARSE AGGREGATE IN PORTLAND CEMENT CONCRETE. THE USE OF BEACH SAND AS A FINE AGGREGATE IS ALSO EXPLORED. THE RESULTS PRESENTED IN THE TWO STUDIES INDICATE THAT CONCRETE OF SUITABLE STRENGTHS FOR CERTAIN PURPOSES CAN BE PRODUCED FROM REEF SHELL AND BEACH SAND AGGREGATES EVEN THOURGH THESE AGGREGATES DO NOT MEET THE USUAL REQUIREMENTS CONCERNING GRADING, PARTICLE SHAPE, AND ABRASION LOSS. CONCRETE WITH A COMPRESSIVE STRENGTH OF 2500 PSI, FLEXURAL STRENGTH OF 550 PSI, AND ADEQUATE WORKABILITY CAN BE OBTAINED BY COMBINING 40% (BY WEIGHT) OF BEACH SAND, 60% (BY WEIGHT) CRUSHED REEF SHELL, 6 BAGS/CU. YD. CEMENT AND SUITABLE AMOUNTS OF FLY ASH AND AIR ENTRAINING AGENTS. USES COULD INCLUDE RETAINING WALLS, STRUCTURE FOUNDATIONS, SUBPAVEMENTS, AND CONSTRUCTION INVOLVING MASSIVE CONCRETE. /AUTHOR/
