THE EFFECT OF FINE AGGREGATE GRADATION ON CEMENT AGGREGATE REACTION

A PILOT STUDY ON THE EFFECT OF THE AMOUNT OF SAND-GRAVEL MATERIAL PASSING THE 30 MESH SIEVE ON THE EXPANSION OF CONCRETE WAS CONDUCTED USING SIX DIFFERENT GRADATIONS AND A HIGH ALKALI CEMENT. FOUR OF THE GRADATIONS CONTAINED ONLY A KNOWN REACTIVE SAND-GRAVEL, THE OTHER TWO GRADATIONS CONTAINED THE SAME SAND-GRAVEL SWEETENED WITH 30% LIMESTONE. THE PILOT STUDY INDICATED THAT AS THE AMOUNT OF AGGREGATE PASSING THE 30 MESH SIEVE WAS REDUCED, THE AMOUNT OF EXPANSION WAS REDUCED. THE EFFECT OF AGGREGATE GRADATION WAS NOT EVIDENT ON THOSE MIXTURES IN WHICH LIMESTONE WAS ADDED. /BPR/
