WEBSelf-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good …
Highlights The corrosion resistance of self-compacting concrete (SCC) has not been investigated yet. In the reported study the corrosion resistance of SCC incorporating quarry dust powder, silica fume and fly ash was studied. The chloride permeability of the developed SCC was low to moderate and the corrosion resistance …
The outcome of an experimental study to investigate the potential of using this dust in producing self-compacting concrete (SCC) for structural purposes is reported. SCC mixtures were prepared at a constant water-to-binder ratio of 0.45 using five different replacement percentages of cement by WCBPD ranging from 10 to 25% (by cement …
For M30 grade and w/c 0.5, conventional concrete workability is found to be 0.97. For 20% quarry dust workability is 0.94. Further workability is decreased to 0.93 for 30% replaced concrete. For 40% quarry dust concrete workability is 0.93 and for 50% replacement of quarry dust concrete 0.87 compacting factor was observed.
Based on this observation, the potential material-cost savings in Wisconsin due to the use of quarry fines and Class C fly ash in self-compacting concrete are estimated in this section. 53 In this study, it was assumed that about 400,000 yd 3 of self-compacting concrete (SCC) could potentially be produced in Wisconsin yearly (Table 43).
In order to conserve natural sand, quarry dust (QD) as a waste and sustainable material has been incorporated to replace fine aggregate in SCC. In this study, conventional concrete and quarry dust in self-compacting concrete (QDSCC) mixes consist of 0%, 10%, 20%, 30%, 40% and 50% QD were prepared. The workability test …
