| 要旨 | Nitrogen sorption was measured for a study of the pore structure of low heat Portland cement paste (L-hcp) and high early strength Portland cement paste (H-hcp). The Grand Canonical Monte Carlo method (GCMC) simulated the pore size distribution under various RHs. When relative humidity started to decrease, gel pores gradually disappear. The loss of nitrogen surface area can be explained by C-S-H agglomeration. Based on GCMC, the large capillary pores presented the maximum volume at dried 40% RH. The L-hcp contained the higher porosity than the H-hcp based on the N2 sorption measurements. |
