| Abstract: | A simple formula with no fitting parameters is proposed, with which the strength of cement-treated soil can be calculated at any curing time with the known cement-water ratio (the ratio of the cement mass to the mass sum of the water in the soil and the water in the cement paste) of the cement-treated soil and the corresponding strength at a certain short curing time. The results obtained with this formula basically reflect the law whereby the strength of cement-treated soil increases with the curing time. To further facilitate the use of this formula, the conversion relation of the cement-water ratio to the cement-mixed ratio and the water-cement ratio of the cement paste were presented. In such a way, the strength of cement-treated soil can be predicted directly using the common proportioning parameter of the cement-treated soil. In addition, with the known long-term (within 180 d) target strength of the cement-treated soil, its short-term strength can also be speculated through this formula, on whose basis a formulation design for cement-treated soil may be conducted as well. |
