Question: May I submit compressive strength results from a threepoint curve instead of from individual mix designs to cover all my structural and incidental mixes designed with the same materials? Answer: Yes, for Class AA, AAbarrier rail, A, B and Bcurb gutter machine mixes only.

The curve is known as the grading curve. Calculation. Fine Aggregate: 1. Suitable size in microns(Di0 sieve opening corresponding to 10%finer in the graph ) = 2. Uniformity coefficient (D60/ D10),D to be recieved from the graph ) = 3. Fineness modulus (Total of cumulative % .

concrete mix. The required fineness modulus was achieved by sieving the crushed stone using automatic sieve shaker to maintain the required quantity of retained crushed stone size on each standard sieve. Fineness modulus of,,, and 3 were prepared for the different concrete mixes.

Question1: What is the FM(Fineness Modulus)? Answer: FM( Fineness Modulus is an empirical figure obtained by summing up the cumulative percentage of materials retained on each of the sieve excluding mm sieve and dividing the sum by 100.

Fineness modulus is a crude measure of grading; two aggregates with the same fineness modulus can have very different gradation curves. The fineness modulus of fine aggregate is require for mix proportioning since sand gradation has

This naturally rounded rock dust (D 50 of 300 µm) provides the bottom end of the gradation curve and improves a manufactured sand's effectiveness as a concrete sand. This product can also be blended with our concrete sand to offer of FMs (Fineness Modulus) from to, making it suitable for beach nourishment projects.

included the specific gravity, water absorption, fineness modulus, surface texture, particle shape and colour. The specific gravity and water absorption were conducted in accordance with the ... curves and the physical properties given in Table 2 indicate the aggregates used for the study were within the accepted range for producing concrete.

100 To calculate the fineness modulus, the sum of the cumulative percentages retained on a definitely specified set of sieves needs to be determined, and the result is then divided by 100.

One of the methods to determine the strength of concrete is to find maturity of concrete. Maturity of concrete is defined as Summation of product of age and temperature (Curing). Concrete Maturity = ∑ (Time x Temperature).

Grain Size Analysis ...

The curve is known as the grading curve. Calculation. Fine Aggregate: 1. Suitable size in microns(Di0 sieve opening corresponding to 10 ...

Aug 13, 2013· By carrying out a mortar analysis, the results of the weight retained in grams on each sieve can be entered into our simple spreadsheet which will then chart the shape of the bell curve. By then adding up the accumulated % retained and dividing by 100, you will find the fineness modulus.

The grading curve for the data, obtained in Table 2, is display in Figure 4. The steep slope of the grading curve, which is from A to B ( between 300600 μm size), indicates the greater proportion of these size particles in the sample.

In such cases where the test aggregate yields higher fineness modulus the blend will be hard and in case where it provides a lower fineness modulus it provides a not very cost effective mix.

2 2. CONCRETE AND COMPRESSIVE STRENGTH Concrete is inert mass which grows from a cementing medium. Concrete is a product of two major components, one is the cement paste and another is the inert mass.
