Effect of Hydration of Unreacted Cement in Hardened Mortar with Low W/C on the Long-Term Strength

Article Preview

Through accelerating the hydration by heighening the curing temperature, the effect of the hydration of the unreacted cement in the hardened mortar with low W/C on the long-term strength was investigated. The results show that in the hardened mortar with low W/C, there exists a lot of unreacted cement at the age of 28 days, and when these cement particles hydrate again at the long age, it is disadvantageous to the long-term strength of the mortar. Moreover, the lower the W/C, the lower the hydration degree at the earlier age, and the more disadvantageous to the development of strength at the long age.
