PROPERTIES AND USES OF INITIALLY RETARDED CONCRETE

LOSS OF SLUMP AND WORKABILITY AND HIGHER WATER REQUIREMENT, PARTICULARLY IN WARM WEATHER, OFTEN IMPAIR CONCRETE QUALITY. INVESTIGATION OF CORRECTIVE AGENTS INCLUDED DEVELOPMENT OF A PENETRATION RESISTANCE TEST TO MEASURE RATE AND PROGRESS OF HARDENING WHICH IS DESCRIBED. THE EFFECT OF VARIOUS FACTORS SUCH AS TEMPERATURE, CHARACTER AND AMOUNT OF CEMENT AND TYPE AND AMOUNT OF RETARDING AGENT ON RATE OF HARDENING, EARLY STRENGTH, WATER REQUIREMENT, AND DURABILITY, ARE REPORTED. /AUTHOR/
