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

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

Fineness Modulus - an overview ScienceDirect Topics

The coarseness of sand is expressed by fineness modulus ( Mx ), defined as follows: (5.1) M x = A 2 + A 3 + A 4 + A 5 + A 6 − 5 A 1 100 − A 1. The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6.

Effect of Fineness of Sand on the Cost and Properties of ...

To find out the effect of fineness modulus (FM) of sand on concrete, sand of different FM from 2.0 to 3.0 is chosen. Two sizes of coarse aggregate particles: i.e. 20 10 mm, which are generally used in standard concrete mix, were chosen for the investigations.

THE PROPERTIES OF CONCRETE MADE WITH VERY FINE SAND

This article described the effects of sand fineness upon concrete properties. Fine quartzitic sand was used in mixes with two 20-5 mm coarse aggregates, tunstead limestone and croxden gravel. These were supplied in single sizes and combined for every mix to provide various gradings. Ordinary portland cement was used as the concrete.

Fineness Modulus of Fine Aggregate Fineness Modulus of ...

Fineness Modulus of Fine Aggregate: The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm,

Bulking of Sand in Concrete - Cement Concrete in India

Jul 17, 2020  In the case of proportioning by volume, bulking results in a smaller weight of sand occupying the fixed volume of the measuring box, and the mix becomes deficient in the sand and the resulting concrete becomes honeycombed and its strength is reduced. The extent of the bulkage depends upon the percentage of moisture present in sand and its fineness.
