Abstract EN
Experiments have been conducted to study the effect of addition of fly ash, copper slag, and steel and polypropylene fibres on compressive strength of concrete and to determine the hierarchical order of influence of the mix variables in affecting the strength using cluster analysis experimentally.
While fly ash and copper slag are used for partial replacement of cement and fine aggregate, respectively, defined quantities of steel and polypropylene fibres were added to the mixes.
It is found from the experimental study that, in general, irrespective of the presence or absence of fibres, (i) for a given copper slag-fine aggregate ratio, increase in fly ash-cement ratio the concrete strength decreases and with the increase in copper slag-sand ratio also the rate of strength decrease and (ii) for a given fly ash-cement ratio, increase in copper slag-fine aggregate ratio increases the strength of the concrete.
From the cluster analysis, it is found that the quantities of coarse and fine aggregate present have high influence in affecting the strength.
It is also observed that the quantities of fly ash and copper slag used as substitutes have equal “influence” in affecting the strength.
Marginal effect of addition of fibres in the compression strength of concrete is also revealed by the cluster analysis.
