aggregates and grading of aggregates. Results obtained show that the specific gravity value for the sampled river stone is 2.6. The loose bulk density of the river stone is 1474kg/m3. Water absorptions test conducted on the aggregates gave a value of 0.9%. Crushing value of the river stone aggregates was obtained as 34.5.
Quantifying the particle shape and surface roughness of sands
2023323 Tested materials. In this study, four kinds of natural sand, LBS, BS, CS, and CDG, with sizes ranging from 0.063 mm to 2.36 mm were tested. All sands were oven-dried and sieved following the British Standards BS1377-2 prior to test, and their particle size distributions were shown in Fig. 1.For BS, the number of particles finer than 1.18
Particle-scale mechanics of sand crushing in ScienceDirect
2015101 The numerical samples used in this stone are approximately cubical and initially contain 22,246 spherical particles. When crushing is considered, the number of particles increases to more than 40,000 at the end of the shearing simulations at the highest σ 3 '.The particle size distribution (PSD) before crushing is representative of the poorly
Effect of Manufactured Sand with Different Quality on
20211122 High–strength manufactured sand recycled aggregate concrete (MSRAC) prepared with manufactured sand (MS) and recycled coarse aggregate (RCA) is an effective way to reduce the consumption of natural aggregate resources and environmental impact of concrete industry. In this study, high–, medium– and low–quality MS, which were

Trace and major minerals of (natural and manufactured) sand
2021112 Content of magnetic minerals for manufactured sand (mean [s.d.] value of χ = 736 [386] × 10–8 m3 kg−1) is higher than for river sand (χ = 105 [122] × 10–8 m3 kg−1). Such high values of χ seem to be more favorable for properties of concretes, and hence they lead to a better replacement product. Natural granulation of rock into
An investigation on the particle breakage of Indian River sands
2018131 The Particle crushing was quantified in terms of the relative breakage factors (Hardin, 1985) after each stress increment. Again, considering the effect of initial void ratio on crushing of sand samples, tests on the six river sands were repeated for three different initial void ratio i.e. 0.5, 0.55 and 0.6.
