| Abstract: | Many concrete structures such as dams, canals, roads and floors are
required to have abrasion resistant. Aggregates play an important role on
strength characteristics and abrasion resistance of concrete. Also compressive
strength has a decisive influence on abrasion. In this study, hematite is used
as replacement aggregate for the purpose. This study investigates effects of
different concentrations (10-50% replacement) of hematite on mechanical
properties of concrete. Water/cement ratio and cement content is kept constant
as 0.42 and 400 kg/m3, respectively. It was observed that hematite –
a material with higher density and higher hardness than cement – will increase
both the compressive strength and the wear resistance depending on hematite
content in the mixture. Concrete mixes with adequate workability have been
produced. Correlation between hematite content-compressive strength and wear loss
is equated, and the equation representing wear as a function of cement content
and hematite content provides a high agreement with the experimental results. |
