Effect of lactic acid on the hydration of portland cement

Effect of pH on Sealing Ability of White Mineral Trioxide Aggregate as a Root-end Filling Material

“…Malic acid (25) and tartaric acid (26) retard, whereas lactic acid (27) accelerates the hydration process of Portland cement. Because of the similarity of MTA and Portland cement, these effects might happen to MTA as well.…”

Effect on Concrete Surface Water Absorption upon Addition of Lactate Derived Agent

“…Instead, this indicates a change in material properties during hardening, supported by the fact that cement heat of hydration was affected. Whether this is caused by chemical interaction of HA with the cement matrix [24] is interesting to explore in future work. Further interesting is to assess whether the densification also has a reducing effect on durability-related mechanisms such as freeze-thaw damage with salt scaling or chloride ingress, as is expected for cement containing a minimum of 50% of clinker [25].…”

Improvement of the Properties of Mineral Trioxide Aggregate by Mixing with Hydration Accelerators

“…CLG is currently a premium salt in the rapidly growing functional and fortified food industry owing to its excellent solubility and neutral taste. A CLG solution consists of a hydration retardant (calcium gluconate) (21) and an accelerator (lactic acid) (19), but few studies have examined its effect on the setting properties of MTA.…”

“…Because calcium silicate hydrate gel and calcium hydroxide evolve by crystallization after a hydration reaction, hydration accelerators, such as glucose (17), low-dose (0.1%) citric acid (18), lactic acid (19), and calcium chloride (CaCl 2 ) (20), accelerate the setting reaction.…”
