Alite (approximately Ca 3 SiO 5) provides almost all the "early strength" (strength up to seven days of curing) of cement and a moderate amount of late (>7 days) strength. Belite (approximately Ca 2 SiO 4) provides very little "early strength" and a large amount of late strength.So it can be seen that these small compositional changes have a large effect
