Physical Properties and Microstructure of Concrete with Waste
Therefore, the dust grain size of rock dust is much more important in these cases. Fine dust material acts as an inert filler, which contributes to better filling of the intergranular free space in a composite. This results in a compact cement matrix structure with lower porosity and therefore greater strength and durability [24,33,34].It is seen that use of up to 7.5% of quarry dust as cement slightly enhances the concrete flexural strength when compared to control mix. The trend is same for 7 days and 28 days curing. For above 7.5 % replacement levels there is decrease in tensile strength marginal for 10% and progressing further.Strength Properties of Concrete with Partial Replacement of

Table 5: Sieve analysis of quarry dust. grain size of manufactured sand resulting in better packing of The corresponding values for quarry dust are 0.8 and 5.45, respectively. A well-graded soil has a C u value of 5 or more and a C c value between 1 and 3 [25]. The values indicate that the river sand has a small range of particle size whereas the quarry dust has a wider range of particle sizes.Comparison of physical and mechanical properties of river sand
