A New Concrete Failure Phenomena Due to Sulfate Attack

Abstract:

Based on more than 30 Km field survey, many samples has been got from sluice pier which is collapsed due to sulfate attack. The microstructure of sample and mineral component of separated material was analysis by X-ray diffraction (XRD) and scanning electron microscope-energy dispersion X-ray analysis (SEM-EDAX). The test shows the failure mechanism is contact dissolution associating sulfate attack. The contact dissolution gave chance to sulfate attack. The concrete expand due to sulfate attack accelerate contact dissolution. So concrete can be failure quickly.
