Among which the experiment group using 50% fly ash, 10% silica fume instead of ordinary Portland cement shows rather better durability either in standard curing or the accelerated aging experiment.

Real-time Fourier-transformed infrared spectroscopy (FTIR) was used to monitor the curing process of hybrid sol, indicating the formed imide group decreased with increasing titania content.

Result the effect of the observed group is very obvious, and the curing days are very short, at the same time it also can reduce the chance to damage the brain.
