X-ray microtomography (microCT) of the progression of sulfate attack of cement paste

High-resolution X-ray computed tomography (i.e., microCT or microtomography) was used to study the sulfate attack of cylinders of Type I cement paste cast with water–cement (w/c) ratios of 0.45, 0.50 and 0.60. Damage levels in samples exposed to a Na 2SO 4 solution with 10,000 ppm sulfate ion concen...
