| description | Ground granulated blast furnace slag–pulverized fly ash (GGBS-PFA)
cement concrete is widely used in the contemporary concrete industry. But both
GGBS and PFA are incompatible with polycarboxylate (PCE) polymers as reported
in previous studies. It can be seen by the segregation effect and bleeding of ternary
blended cement concrete containing PCE in its fresh state. As such, the ratio of α-
methoxy-ω-hydroxy-poly(ethylene glycol) (M-PEG) to methacrylic acid (MAA) was
adjusted to reduce the water demand of the GGBS-PFA ternary blended cement
concrete while maintaining favorable segregation and bleeding resistance. This study
was conducted to investigate the effect of PCE polymers with varying main chain
densities (M-PEG) and side chain densities (MAA) on fresh and hardened of GGBSPFA
ternary blended cementitious composite properties. A total of five PCE
polymers were designed and synthesized with various main chain densities (M-PEG)
and side chain densities (MAA) for use in concrete fabrication. Before concrete
fabrication, the mix design parameters for the concrete fabrication were optimized
with respect to binder compositions, ratio of coarse aggregates to fine aggregates
(CA/FA), PCE polymers dosage and the designed water-binder (w/b) ratio. The
fabricated concrete was tested in terms of workability, strength development and
durability performance while the properties of the GGBS-PFA cement paste with the
synthesized PCE were accessed. Furthermore, an analysis of PCE polymer
characteristics was carried out using Fourier Transform Infrared Spectroscopy
(FTIR) and Nuclear Magnetic Resonance (NMR). |
