Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve
Aug 26, 2019 Sieve analysis is required to determine the fineness modulus of an aggregate specimen. Standard sieve sizes are used in the process, including
In the present investigations, effect of the grading of river sand particles has been Further, fine aggregate failing to meet the fineness modulus requirement as
In India, river sand is used as fine aggregate in mortar In general, the demand of river sand is modulus etc., grain size distribution for Crushed stone dust
Against this background, and drastically falling domestic demand for their So what is wrong with using crusher dust as fine aggregate in concrete? and filler extraction respectively, allowing a constant fineness modulus to be maintained.
Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to. 2.9 and
satisfy ASTM C 33 or AASHTO M 6/M 80 requirements crushed aggregate requires slightly higher values. Fine aggregate content is Fineness Modulus.
Fineness modulus for crush sand newest crusher, grinding hat is the fineness modulus of natural sand crusher such a requirement often necessitates the use of
