| description | The higher material cost of self-compacting concrete (SCC) as compared to
normal vibrated concrete is mainly due to its higher cement content. In order to
produce economical SCC, a significant amount of cement should be replaced with
cheaper material options, which are commonly found in byproduct materials such
as limestone powder (LP), fly ash (FA) and raw rice husk ash (RRHA). However,
the use of these byproduct materials to replace the high volumes of cement in an
SCC mixture will produce deleterious effects such as strength reduction. Thus, the
objective of this paper is to investigate the optimum SCC mixture proportioning
capable of minimizing SCC’s material cost. A total of fifteen mixes were
prepared. This study showed that raw rice husk ash exhibited positive correlations
with fly ash and fine limestone powder and were able to produce high
compressive and comparable to normal concrete. The SCC-mix made with
quaternary cement-blend comprising OPC/LP/FA/RRHA at 55/15/15/15 weight
percentage ratio is found to be capable of maximizing SCC’s material-cost
reduction to almost 19% as compared with the control mix |
