Autogenous Curing of Cold-Bonded Fly-Ash-Aggregate Concrete

Properties of cold bonded quarry dust coarse aggregates and its use in concrete

“…This can be attributed to the inclusion of inclusion of low strength aggregate in the matrix. The observations in the present study corroborates with the study of the fly ash aggregate concrete by Joseph and Ramamurthy [34]. A close up view of concrete cube specimens failed in compression is shown in Fig 7. In weak aggregate weak matrix combination of 250 Q75F10C15, partial splitting of aggregates was observed and is given in Fig 7(a).…”

“…The compressive strength of concrete containing cold bonded aggregate in this study is found to be comparable with the results given in the literature. This indicates that the artificial cold bonded aggregates prepared in this study can be recommended for the various applications as proposed in the case of fly ash aggregate by Priyadharshini et al [21], Gesoglu et al [35], and Joseph and Ramamurthy [34].…”

“…Sivakumar and Gomathy [33] reviewed various materials and the method of preparation of cold bonded aggregate using cement as a binder. Joseph and Ramamurthy [34] reported that artificial lightweight cold bonded fly ash aggregate is useful in preparing concretes of strength up to 52 MPa. The test results of Gesoglu et al [35] indicated that the specific gravity of fly ash-ground granulated blast furnace slag artificial aggregate increases with an increase in the cement content.…”

Cold-bonding process for treatment and reuse of waste materials: Technical designs and applications of pelletized products

“…mist-cured, aircured, and sealed) on LWC made by FA aggregates do not indicate significant differences in terms of compressive strength and degree of hydration. This latter result can be ascribed to the autogenous curing in the cold-bonded aggregates (G. Joseph & Ramamurthy, 2011).…”
