- Abstract
- Three different superplasiczers such as PNS (poly naphthalene sulfonate), PNS with additive (copolymer of acrylic acid, acrylic ester and maleic acid), and PC (polycarboxylate) were used to investigate the effect of superplasticizer types on the properties of mortar incorporating metakaolin (MK). When MK was hydrated, diffusion behaviors of aluminate and silicate were examined separately at 1, 3, 7 and 28 days by X-ray diffraction, SEM/EDS and for considerable effect on the hydration rate and hydrates types. The results showed that PNS with additive were effective in promoting pozzolanic reaction. Considering the workability and the compressive strength, it is desirable to use PNS with additive in the production of high-performance concrete incorporating MK.
