Chloride ion resistance of self-compacting concretes incorporating volcanic materials

Abstract

This paper examines the effect of incorporating considerable amounts of Colombian volcanic material to self-compacting concrete (SCC) as a pozzolanic addition for rheological improvement, including the effects on the mechanical properties and chloride resistance. In particular, the volcanic materials used as parts of binary and ternary concrete mixtures in this study were Tolima (TVM), Puracé (PVM) and Bocayá (BVM). This paper shows that incorporating volcanic materials, both inert (TVM) and pozzolanic (PVM and BVM), results in SCCs with good workability, moderate mechanical properties and high durability in the presence of aggressive agents such as chlorides.
