Table 1 Setting Time of Concrete at Various Temperature

Effect of TiO2 Nanoparticles on Physical and Mechanical

It was found that low temperature delayed the process of cement hydration while TiO2 nanoparticles had a positive effect on accelerating the cement hydration and reducing the setting time in terms of the results of the setting time test, hydration degree
