In conventional Portland cementitious material, the hydration products of Alite play an important role in providing early strength, however the system with imperfect early strength will crack in service due to shrinkage, which is the main reason that impair the durability of concrete and limit the combination of supplementary ementitious materials (SCMs).Yeelimite(C4A3$) has a fast hydration rate and shows extraordinary early strength along with low sintering temperature, proper expansion in the hydration process and other merits.If introduced into Portland cement clinker to form Alite-Yeelimte system,C4A3$ will significantly improve the performance of traditional Portland cement only if take full advantages of both mincrals which dont coexist during sintering due to different stable temperatures.
