| Abstract: | Effcets of polycarboxylic water reducer compounded respectively with aliphatic series, melamine series and naphthalene series were studied without low-molecular weight retarder added, hence three kinds of compounded water reducer were prepared. Effects of compounded water reducers on hydration rate of ld hardened cement paste were researched by XRD, SEM, IR analyses. Mechanism of these water reducers was discussed according to elapsed time change of ζ potential on cement particle surface. Some properties of cement paste and concrete with the compounded water reducer were also tested. |
