THE EFFECTS OF SEA-SHELLS IN CONCRETE AGGREGATES

IN JUNE 1968 THE GREATER LONDON COUNCIL (GLC) PUBLISHED A MARINE AGGREGATES SPECIFICATION WHICH LIMITED THE PERMISSIBLE AMOUNT OF SHELL IN AGGREGATE FOR REINFORCED CONCRETE WORK. AS A RESULT THE SAND AND GRAVEL ASSOCIATION UNDERTOOK A LABORATORY RESEARCH PROGRAM TO DETERMINE THE EFFECT OF SHELL ON THE PROPERTIES OF CONCRETE. THE CONCLUSIONS OF THAT WORK ARE REPORTED. THEY DEMONSTRATE THAT AMOUNTS OF EITHER FLAT OR HOLLOW SHELL OF WELL BEYOND TWICE THOSE PERMITTED BY THE GLC SPECIFICATION CAN BE USED IN STRUCTURAL CONCRETES WHILE MAINTAINING ALL THE REQUIRED PROPERTIES. /A/RRL/
