Abstract
The high accuracy and the adaptability to the construction control of the strength prediction method of cement-treated soil with volume solid content was shown by the discussion using the mixing test data of the actual project. The strength-time relationships of 3 cement-treated marine clays were obtained by laboratory experiments, and it was shown that the strength increase process can be divided into two stages, the first stage within 3 days after mixing and the second stage 3days after the mixing. For both stages, the equations of the relationship between strength increse and curing time, which have 5 parameters, were proposed. The parameters of proposed equations were determined using the mixing test data of 12 marine clays. Comparing the measured strength with the predicted by the proposed, it was concluded that the equations successfully predicted the relationship of strength-increase with time.
