The fineness of the original sand used in a concrete mixing plant

Study on the Fluidity and Strength Properties of High

Oct 17, 2012 · Recently, it has been difficult to get natural sand for concrete due to an insufficient supply in Korea. Crushed sand was thought as a substitute and previous research has been focused on low fluidity and normal compressive strength (24–30 MPa). Study on high performance concrete using crushed sand is hardly found in Korea. In this study it was investigated that the effect of the ...
