A Study on Performance of Crusher Dust in Place of Sand
2016-8-4 sand mixes attained high densities, high CBR values (>10%) and shear strength values (ϕ >360).Hence, it is concluded that 30-40% addition of sand to crusher dust yields satisfactory results and can be used as sub-grade and fill materials in various geotechnical construction activities.

A DEM investigation on crushing of sand particles
2020-4-1 1. Introduction. Particle crushing is closely related to many geotechnical engineering problems and is an interesting topic that has been studied intensively in recent decades (e.g., Milligan, 2003, Arslan et al., 2009).Particle crushing is affected by many factors, e.g., size, heterogeneity, morphology, mineralogy and environmental factors (e.g., erosion, fire and flood), making it a

Crushed rock sand An economical and ecological
2016-9-1 It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve. Several studies have been conducted in the past to investigate the effect of partial replacement of Natural River sand with crushed rock sand. Celik and Marar (1996) concluded that partial replacement upto 30% leads to decrease in slump

Aggregate Crushing Value Test Crushing Value Of
2021-11-24 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value..
