Coarse sand: its fineness modulus is 3.7-3.1, the average particle size is over 0.5 mm. Medium sand: its fineness modulus is 3.0—2.3, the average particle size is 0.5—0.35 mm. Fine sand: its fineness modulus is 2.2—1.6, the average particle size is 0.35—0.25 mm.
The artificial sand is basically medium-coarse sand, the fineness modulus is between 2.6 and 3.6, the particle gradation is stable and adjustable, and contains a certain amount of stone powder. Also Know, how is sand created? Sand forms when rocks break down from weathering and eroding over thousands and even millions of years.
Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from ...
The fineness modulus of sand differs for each sand quarry. The purpose of this research is to analyze the effect of fineness modulus of fine aggregate (sand) on concrete compressive strength. The sand quarry taken in this study are from three sand quarry in Aceh Tamiang District. They are Johar quarry, Tanjung Karang quarry, and Alur Bamban quarry.
• Plastering Works: finest modulus of fine sand should not be less than 1.5 and silt contents should not be more than 4%. • Concreting Works: coarse sand should be used with finest modulus 2.5 to 3.5 and silt contents should not be more than 4%.
