An Evaluation of Shrinkage Model Based upon Microstructure of Blended Cement Pastes

Abstract:

As shrinkage in concrete leading to the subsequent cracking and reducing durability, the study on shrinkage is quite important. Based on microstructure of pores obtained from Nitrogen absorption method and mechanical testing, a numerical shrinkage model was built. The standard shrinkage test results show consistent in the blended cement pastes with different water-to-cement ratioand admixture content to predict shrinkage values, which confirmes the shrinkage model based upon microstructure of blended cement pastes.
