Influence of Intermediate-Sized Particle Content on Traditional Dry-Rodded and Vibrated Aggregate Packing
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
The addition of standard intermediate aggregate (IA) content may provide desired intermediate-sized aggregate particle (ISA) content that can enhance the aggregate gradation and predictability of the aggregate packing (k) and Portland cement concrete consistency. This study evaluates the effect of the ISA on the average variation between traditional dry-rodded and vibrated aggregate packing (Δk) results. Gradation factors were determined and plotted on the Modified Coarseness Factor Chart (MCFC) seeking to identify Δk-ISA content correlations and to investigate a relationship between ISA and concrete consistency. The aftermath of 96 tests were grouped in three intervals determined by gradation curve resemblance. The results indicated that when ISA was between 25 and 27 % (by weight), Δk reached its lowest level: 1.7 %. Also, the optimized gradation (B6) displayed ISA = 26 % and fell right at the center of the MCFC’s Workability Box (WB). Lastly, aggregate blends with 10 < IA < 11 % (by weight) translated into 25 < ISA < 27 % and surrounded the WB of the MCFC. The study concludes that adding IA to concrete can increase adherence between concrete design and placement, besides providing better consistency to concrete.
