Abstract
The extent of modification of the hydration process in a cementitious material by external agents depends on its mix components. In this study, the effect of D-galacturonic acid on the hydration of fiber-reinforced engineered cementitious composites (ECC) and ordinary mortar was investigated. The final setting time was monitored as well as the flexural or compressive strengths during and after 28 days of curing. It was observed that D-galacturonic acid retarded the setting of both materials, and the presence of D-galacturonic acid in the curing water slightly modified their strength attainment. However, in both cases, the extent of the retardation or modification was more severe for the ordinary mortar than the ECC. Moreover, the acid had an insignificant effect on the strength of either hardened ECC or mortar after 28 days of water curing. Therefore, the hydration and resulting modification of ECC by D-galacturonic acid was more tenacious than that of ordinary mortar
