Abstract
Self compacting concrete (SCC) is a type of concrete which can flow and spread through
reinforcement and narrow sections which fills the empty spaces completely without any mechanical
vibration. This type of concrete requires large quantity of powder, for which either fine pozzolanic
(e.g. fly ash, ground granulated blast furnace slag and silica fume etc) or non-pozzolanic additions
(crushed limestone or sand stone etc) are used. The composition of this blend of cement and filler
material is significant in SCC, as high amount of cement with lower water content may cause
autogenous shrinkage. Therefore, the use of non-pozzolans material with cement needs to be
investigated. The concrete industry is among the largest consumer of raw materials. Limestone fillers
are generally used in concrete. As marble stone is of limestone origin i.e. marble is formed by
metamorphism of limestone. The effect of addition of non-pozzolans powder waste from marble
industry is studied for its suitability in SCC. This was done keeping in view the requirement of fines in
SCC and to find an effective utilization of waste marble powder (WMP). For this, five different SCC
mixes were prepared, one without WMP and four other with varying amounts of WMP. These mixes in
fresh state were tested for their flowability, passing-ability and segregation resistance. Hardened
concrete was tested for compressive and flexural strengths. It was found that the locally available
WMP can be effectively used as filler in developing SCC. Furthermore, it can be concluded that the
addition of WMP up to 15% by cement weight can lead to a desirable SSC properties.
