Learn MoreA comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich, if the cement is included in the modulus figures.

Learn MoreAccording to the fineness modulus (MX), the specifications of machine-made sand can be divided into 4 types: coarse, medium, fine and extra fine: 1. Coarse Sand: the fineness modulus is 3.7-3.1, and the content of particles larger than 0.5mm exceeds 50% of the total weight, and the average particle size is 1mm-0.5mm. 2.

Learn MoreSep 01, 2014 · What is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Fineness Modulus of Sand Why to Determine Fineness Modulus? Fineness modulus is generally used to get an ...

Learn More28. Relationship Between Fineness Modulus and Screen Size. At present, the general requirement of fineness modulus of artificial sand is 2.6-3.0, and the screen size is generally recommended to be 3.0mm or 3.5mm. If the content of stone powder is large, 2.8mm sieve can be used.

Learn MoreFor the adjustment of stone powder content, the fineness modulus can be reduced and the fine particles can be increased by means of reducing the feeding amount of rod mill and increasing the steel rod amount. The stone powder content of artificial sand can be increased by recycling equipment such as hydrocyclone. 2.
