Vimalanandan (2019) In this analysis, GGBS used as a partial replacement of cement, crusher dust as a partial replacement of FA, SSW as a partial replacement of CA.However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts. In response to this, this study investigated a range of sands produced by an industry sized KEMCO V7 crushing plant, which reprocesses crusher dusts in a modified impact crusher and classifies the size of An Investigation into the Use of Manufactured Sand as a

The aim of this paper is to evaluate the influence of the crushing process used to obtain recycled concrete aggregates on the performance of concrete made with those aggregates. Two crushing methods were considered: primary crushing, using a jaw crusher, and primary plus secondary crushing (PSC), using a jaw crusher followed by a The replacement level considered for the study were 20, 40, 60, 80 & 100% by weight.
