Sand Grading Influence on Air Entrainment in Concrete

Generally the percentage of air entrained in concrete increased with decrease in fineness modulus of sand. Quantity of air appears to be a function of the quantity of No.30-No.50 sand. Effect of grading and quantity of sand on other properties of fresh and hardened concrete is noted.

What Is Fineness Modulus of Sand? - Civil Lead

Fineness modulus = (Summation of cumulative % of weight retained up to 150 microns) / 100. Fineness modulus = 240/100. Fineness modulus = 2.4. So, in our case, it is Fine Sand.

What is Fineness Modulus of Sand (Fine Aggregate) and ...

31-07-2016  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 analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.

The Importance of Fineness Modulus Concrete

01-01-1994  ASTM C 33 requires the FM of fine aggregate to be between 2.3 and 3.1. The higher the FM, the coarser the aggregate. Fine aggregate affects many concrete properties, including workability and finishability. Usually, a lower FM results in more paste, making concrete easier to finish.

What Is Air-Entraining Admixture And Its Effect On Concrete

It was established that the quantity of air increased from the lowest fineness modulus 07 sand to a peak at about F.M. of 2.5, and, thereafter, decreased sharply. Sand having a size of about 300 and 150 microns showed a significant effect on the quantity of air entrainment.

The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6. And if M x is within 3.7 ~ 3.1, it is coarse sand; if M x is within 3.0 ~ 2.3, it is medium sand; if M x is within 2.2 ~ 1.6, it is fine sand; and if M x is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is

Air Entrainment in Concrete: 10 Factors Concrete

It has been established that the quantity of air increases from the lowest fineness modulus of sand and attains the peak value at fineness modulus (F.M) of about 2.5 and afterwards decreases sharply. The sand fraction of 300 and 150 micron has shown a marked effect on the quantity of air entrainment.
