Effect of Curing Time on the Pore Structure of the Portland Cement Concrete
In this paper,the influence of curing time on the compressive strength and pore structure of the Portland cement concrete was investigated.The phase composition and morphology of hydration products of Portland cement were analyzed with X-ray diffraction (XRD).In addition,the porosity and pore distribution of the concrete were also researched using mercury intrusion porosimetry (MIP),surface area and porosity analyzer (BET).The results show that the influence of curing time on the compressive strength and pore structure of the concrete is obvious.With curing time increasing,the compressive strength of the concrete increased and the porosity decreased.The corresponding fractal dimension of the pore and the microstructure were changed,as well.With time increasing,more hydration products were produced.
